Granola vs Wispr Flow: AI notetaker comparison

There's no denying the similarities between Granola and Wispr Notetaker, the AI notetaking arm of the Wispr Flow platform. Both record your meetings from your laptop or phone without sending a bot into the call, then hand you a transcript and summary when it ends. But, look closer, and differences start to emerge. People are increasingly finding reasons to switch to Wispr Notetaker, including:

  • Accuracy. Granola made 32% more meaningful errors than Wispr Notetaker in testing involving 18,000 words and 13 diverse content segments.
  • Post-meeting QA. Every transcript gets a second look after the call to catch mistakes before your summary is written.
  • Speaker identification. Speakers get their real names in Slack huddles, and in conference rooms when people are mentioned, not just "Me" and "Them."
  • A personal dictionary that evolves with each use. It learns your colleagues' names and your company's jargon from your calendar, Slack, Gmail and the corrections you make, so there's no word list to keep up.
  • Caters to a broader audiences.  With Wispr Flow, you can sign up with any email address, not just a Google or Microsoft account. Currently, some future Granola users trying to sign-up with a non-professional email are wait-listed.
  • Stronger customer reviews. G2 reviewers rate Wispr Flow Notetaker 4.8 out of 5 across 41 reviews, compared with Granola's 4.6 across 197.
  • Wispr Flow dictation for every app comes included.

How Wispr Notetaker and Granola compare, feature by feature

The two tools record the same way, so the differences come down to what the transcript says, who it names and what you can do with it afterward.

Granola details checked against granola.ai and docs.granola.ai on November 7, 2026.

Who said what: where each tool gets speaker names

Verdict: Wispr Notetaker for Slack huddles and in-person meetings. On Google Meet, Zoom and Teams, both tools name speakers.

Granola reads names from the meeting app

Granola's speaker tags pull display names from Google Meet in Chrome and from the Zoom and Teams desktop apps. Everywhere else on desktop, including Slack huddles, Webex and in-person meetings, the transcript shows "Me" and "Them." Granola's help center also notes that it can't tell apart several people speaking through one conference-room device.

Wispr Notetaker builds names from context

After each meeting, Wispr Notetaker names speakers using your calendar invite, your personal dictionary and cues in the conversation, such as someone saying "thanks, Priya," and it works in Google Meet, Zoom, Teams and Slack huddles, and in person when people are mentioned. Webex and Discord calls get numbered speakers for now. If anyone is still unlabeled, you name them once and the label applies across the transcript.

When tested, Wispr Notetaker separated speakers that Granola bucketed together as "Them"

When we played 13 recordings to both tools at once and compared the transcripts, Granola labeled every line "Me" or "Them." Wispr Notetaker separated speakers in 7 of the 8 multi-speaker recordings, often matching the official transcript turn by turn. Because the audio played aloud from a speaker rather than through a meeting app, the test mirrors an in-person meeting, where Granola's platform-based speaker tags can't apply.

Accuracy test results: Wispr Notetaker vs Granola

Verdict: Wispr Notetaker, with its biggest lead in unscripted conversation.

In November 2026, Wispr Flow ran Wispr Notetaker and Granola side by side on 13 recordings totaling about 18,050 words, then checked both transcripts against transcripts published by each source. The test measured transcription accuracy, not the quality of each tool's summaries.

Granola made 32% more meaningful errors than Wispr Notetaker. The more the source material mirrored real human interactions, the bigger Notetaker's lead.

A meaningful error is one that would leave a reader with a wrong or unreadable version of what was said, such as a wrong word that changes the meaning, garbled text, an invented line or a dropped line. See the full methodology.

When there was simple narration, Wispr Notetaker and Granola performed the same

With one narrator reading clean, published text, there was almost nothing to separate the two tools. Neither made a meaningful error in The Sun Also Rises, The Secret of the Old Clock, The Painted Veil or the children's story Stone Soup. Where they differed, it came down to a word or two: Wispr Notetaker's transcript of The Sun Also Rises matched the book exactly, while Granola's transcript of The Secret of the Old Clock was closer to the text by two words. The only meaningful errors on either side were two in Wispr Notetaker's transcript of Babbitt.

When the content was conversational or unscripted, Wispr Notetaker outshone Granola

To reflect the conversations real users have every day, we tested a wide range of unscripted audio, including:

  • Podcast interviews with several guests
  • A live, in-person interview in front of an audience
  • A podcast mixing hosts, experts and archival clips
  • A congressional hearing
  • Supreme Court oral arguments

The messier the content, the more the gap between Wispr Notetaker and Granola grew. That matters because most meetings are far from perfect: people talk over one another, backtrack mid-thought and lean on filler words.

Case in point: Freakonomics Radio's live interview with novelist Harlan Coben had all of these characteristics. Granola dropped short lines from the back-and-forth and made about 32 meaningful errors to Wispr Notetaker's 20.

Full results for each recording are in the appendix.

Examples of meaningful errors

  • In the House Science Committee hearing, Granola wrote "Banana centers" for "for nine centers."
  • In the Vox Explain It to Me episode, Granola wrote "Chris and Boots" for "Puss in Boots."
  • In the Freakonomics Radio episode on hamburger prices, Granola wrote "He said" for "You said," turning the host's quote of his guest into a quote of someone else.
  • In the Freakonomics Radio interview with Harlan Coben, Granola dropped Coben's line "No, not making big big bucks," so the transcript reads as if he agreed he was.
  • In the same Coben interview, Wispr Notetaker wrote "jala na fail" for "how did I not fail."
  • In the FCC v. AT&T argument, Wispr Notetaker wrote "interim effect" for "in terrorem effect."

To see how both tools handle your own meetings, run them side by side on one call.

Wispr Notetaker vs Granola: Signing up, free plans and team controls

Verdict: Wispr Notetaker. It takes any email address, and its free plan includes transcripts in AI tool access.

This is where the two tools differ most for people outside a single corporate account.

Granola signs you in through Google or Microsoft only

Granola offers three ways to sign in: a Google account, a Microsoft account or enterprise SSO. There's no option to sign up with an email and password, and Granola's help center says Gmail users may be sent through a waitlist step while it finishes allowing Gmail accounts. That's built for people with one company account. It's a poor fit for students, for anyone using a notetaker personally, and for freelancers juggling several clients.

Wispr Flow accepts Apple, Google, Microsoft, SSO, or any email address with a password.

Granola's free plan hides older notes

Granola's free Basic plan records unlimited meetings, but only notes from the last 30 days stay visible in the app. Older notes are stored until you upgrade or export them. The same 30-day window applies when you connect Claude or ChatGPT: Basic reaches your own notes from that window, without transcripts.

Wispr Notetaker's free plan caps recordings at 50 a week instead. Only meetings of 5 minutes or longer count, and imports don't count. Transcripts, summaries and notes all reach your AI tools, and Wispr Flow dictation is included. Pro removes the weekly limit and keeps your full Notetaker history.

Teams get a consent check before recording

Neither tool sends a bot, so participants may not know they're being transcribed unless someone tells them. Granola can post an automatic notice in the meeting chat. One company we spoke with that evaluated both tools found it lacked a manual confirmation step, which Wispr Notetaker offers.

On Wispr Notetaker, admins can require people to confirm they've obtained consent before a recording starts, available on request. Notetaker can also post a consent notice in supported meeting chats or add one to the calendar event.

What a sales team found running both

In one 46-person sales team pilot where reps used both tools, 61% said they'd choose Wispr Notetaker going forward and 35% chose Granola. On transcription and speaker accuracy alone, opinion was close: 32% rated Wispr Notetaker better, 30% rated Granola better, and the rest saw no difference.

Using your meetings in Claude, ChatGPT and other tools

Verdict: Split. Wispr Notetaker gives AI tools more on the free plan; Granola has more built-in integrations.

Both tools connect to AI assistants through MCP, so you can ask Claude or ChatGPT what was decided last month or have it draft a follow-up from what was actually said. The difference is how much of your meeting history each plan lets through, and where your notes can go without an AI tool in the middle.

Wispr Notetaker connects to Claude, ChatGPT, Gemini, Cursor and other MCP tools, and the free plan sends transcripts, summaries and notes. If you're moving from Granola, you can keep Granola's connector running alongside Wispr Flow's, so one prompt searches old and new meetings together.

Granola's MCP works on every plan. Basic reaches your own notes from the last 30 days without transcripts, and Business at $14 per user per month opens your full history, transcripts and public workspace notes. Granola also has more built-in destinations: Slack on the free plan, and Notion, HubSpot, Attio, Affinity and Zapier on Business, plus an API with webhooks. If you want notes landing in your CRM automatically, Granola does more of that today.

Team collaboration: sharing meetings with your team

Verdict: Split. Granola is better for organizing a shared team archive; Wispr Notetaker is better for getting the full record to the right people after each meeting.

Both tools keep notes private until you share them, and both let teammates read shared meetings and ask questions across them. The difference is how that sharing is organized.

Wispr Notetaker shares meeting by meeting, with the transcript when you want it

  • Share a note with only the people you invite, with anyone who has the link, or, on enterprise accounts, with everyone at your company's domain. You can set the default for new notes.
  • An email invite gives teammates the full transcript as well as the summary, while a link shares the summary alone.
  • Auto-share can send notes to calendar attendees after each meeting, and the calendar event can carry a link to the notes.
  • Notes shared with you land in a Shared With Me tab, show up in search, and feed Ask Wispr, which answers questions across your meetings and teammates' shared notes with citations.
  • On Pro, your team shares one dictionary and set of snippets, so the names and terms one person adds work for everyone.
  • Anyone you share with can open the notes in a browser without a Wispr Flow account.

Granola organizes shared notes into spaces and folders

Every Granola workspace has a Team Space, plus custom spaces for departments or projects, with folders inside them. Notes from a recurring meeting can file into a folder automatically, and on Business, folder rules can post summaries to Slack and sync them to HubSpot. Granola Chat answers questions across a whole space or folder, and people without a Granola account can read shared notes and chat with them, though web viewers don't see transcripts.

If your team wants a shared library organized by project, Granola's spaces and folders are more built out. If you'd rather share meeting by meeting, give the right people the full transcript and keep one shared vocabulary across the team, Wispr Notetaker covers it.

Dictation: Wispr Flow vs Granola Voice Typing

Verdict: Wispr Flow. It's a full product on every device, while Granola's Voice Typing is a desktop beta.

The Granola vs Wispr Flow question now reaches beyond meetings. In late October 2026, Granola added Voice Typing, which types what you say into any app on your computer.

Granola Voice Typing is a free beta on Mac and Windows, with mobile coming soon. You hold a key and speak, and it pastes cleaned-up text where your cursor is, removing filler words, adding punctuation and adjusting to the app you're writing in.

Dictation is Wispr Flow's core product, and it works in any app on Mac, Windows, iPhone and Android, in more than 100 languages. It learns the names and jargon you use, keeps a personal dictionary you can add to, saves snippets for text you repeat and lets you set styles so a text sounds casual and an email sounds formal.

  • Wispr Flow dictation works on your phone today, while Granola's is desktop-only for now.
  • Wispr Flow dictation is a full product, while Granola labels Voice Typing a beta.
  • Granola's Voice Typing is free on every plan, while Wispr Flow's free plan has a weekly word limit that Pro removes.

Pricing and free plans

Verdict: Wispr Flow. Billed annually, Pro costs less than Granola Business and includes unlimited meetings and dictation. Month to month, Granola is $1 cheaper.

Billed monthly, Wispr Flow Pro costs $15 per user and Granola Business costs $14. Wispr Flow Pro drops to $12 per user per month when billed annually.

Free plans

Wispr Notetaker's free plan costs $0 and allows 50 recordings a week, with AI tool access and Wispr Flow dictation included. Granola's free Basic plan also costs $0 and records unlimited meetings, but only the last 30 days of notes stay visible.

Plans for individuals and teams

Wispr Flow Pro costs $12 per user per month billed annually, or $15 monthly, and adds unlimited meetings, unlimited Notetaker history and unlimited dictation. Teams that need SSO and admin controls can move to Wispr Flow Growth, at $18 per user per month billed annually ($23 monthly) for dictation only, or $26 ($33 monthly) with unlimited Notetaker access added. Granola Business costs $14 per user per month and adds full history, integrations and full MCP access.

Plans for large organizations

Wispr Flow Enterprise is priced on request and adds admin controls, with no model training on meeting data. Granola Enterprise starts at $35 per user per month.

Prices checked on Wispr Flow's pricing page and granola.ai on November 7, 2026.

Privacy and your data

Verdict: Tie. Granola deletes audio as soon as it transcribes; Wispr Flow keeps it briefly but adds admin controls and BAA support on Growth and Enterprise.

Wispr Notetaker encrypts meeting audio and keeps it only for a limited period, long enough to create your transcript, let you resume a meeting and check quality, then deletes it automatically. Transcripts and summaries are stored in Wispr Flow's cloud, and you can delete any meeting, transcript or note at any time. Notetaker doesn't create voiceprints or biometric profiles of anyone on your calls.

On Free and Pro, a setting lets Wispr Flow use your content to improve its models; it's on by default, and you can turn it off in settings. Model training is disabled for every Enterprise account. On Growth and Enterprise, organizations with a signed HIPAA Business Associate Agreement can use Notetaker, with some sharing features restricted. Full details are in the privacy policy.

Granola caches meeting audio only while it transcribes, then deletes it from its own systems and any third-party services, so there's no recording to replay. On its Basic and Business plans, Granola uses anonymized meeting data to train its own models by default, and you can opt out on any plan. Enterprise workspaces are opted out by default, and Granola contractually bars third-party AI providers from training on your data. Details are in Granola's security and privacy FAQ.

Granola's bright spots

Granola is a well-liked product, and the teams we spoke with who use it rarely had harsh words for it. These are the areas where it's stronger today:

  • Languages. Granola transcribes 32 languages on desktop, and it switches between them within a meeting. Wispr Notetaker supports 21.
  • Built-in integrations. Notion, HubSpot, Attio, Affinity and Zapier connect directly on Business, without an AI tool in between.
  • Recipes and templates. Teams we spoke with leaned heavily on Granola's recipes, saved prompts that shape summaries for interviews, sales calls and other meeting types. One field sales rep in a pilot told us he relied on them for his customer visits.
  • The notepad. If you like typing your own notes during a call, Granola builds its summary around them, keeping what you wrote and filling in the rest.
  • Snapshots. On Mac, Granola automatically captures shared slides, dashboards and documents into your notes.
  • More ways to capture away from a laptop. Granola has an Apple Watch app and can transcribe outbound phone calls you place through its own dialer.

Wispr Flow's bright spots

Wispr Notetaker is the newer product, and it already leads in several places that matter day to day:

  • Accuracy in real conversation. In our side-by-side test, Granola made 32% more meaningful errors, and the gap was widest on a live, unscripted interview.
  • Speaker names beyond the meeting app. Notetaker names speakers from your calendar invite, dictionary and the conversation, including in-person meetings, and you can fix any label once across the whole transcript.
  • A second pass on every transcript. After each call, Notetaker reviews the recording again to catch mistakes before it writes your summary.
  • Open sign-up. Apple, Google, Microsoft, SSO or any email address all work, so freelancers and students aren't shut out.
  • Your meetings in AI tools, free. The free plan sends transcripts, summaries and notes to Claude, ChatGPT and other MCP tools.
  • Built for back-to-back days. Notetaker detects calls that aren't on your calendar and hands off cleanly between consecutive meetings.
  • Dictation everywhere. Wispr Flow dictation works in any app on Mac, Windows, iPhone and Android, in the same subscription.

Switch from Granola and get up to 12 months of Wispr Flow free

If you're paying for Granola, switching doesn't mean losing the time you've already bought. Wispr Flow covers whatever is left on your paid Granola plan with Wispr Flow credit, then adds up to three bonus months, for up to 12 months free. Upload your Granola receipt on the Granola switch page to claim it.

Your meeting history comes with you, too. Wispr Notetaker imports Granola's export, so past notes, summaries and transcripts stay searchable next to new ones. If you're on Granola's free plan, its export includes notes older than 30 days, so the meetings Basic hides become searchable again in Wispr Notetaker. Speaker labels and audio don't carry over, so the sharper transcripts start with your very next meeting.

From there, you get meeting notes with speakers named and dictation in every app, in one subscription, on your laptop and your phone. Claim your free months and let Wispr Notetaker take your next meeting.

Frequently asked questions

Is Wispr Notetaker more accurate than Granola?

In our side-by-side test of 13 recordings and about 18,050 words, Granola made 32% more meaningful errors than Wispr Notetaker (about 49 vs. 37) and 35% more errors overall. Granola edged ahead on audiobooks, while Notetaker led on most conversational recordings, including a live interview and a congressional hearing.

Does Granola label who said what?

Yes, on Google Meet in Chrome and in the Zoom and Microsoft Teams desktop apps, on Mac and Windows, where it reads the names those apps display. Elsewhere on desktop, including Slack huddles, Webex and in-person meetings, its transcript shows "Me" and "Them." Wispr Notetaker names speakers from your calendar invite, dictionary and the conversation in Google Meet, Zoom, Teams, Slack huddles and in-person meetings.

Can I sign up for Granola with a personal Gmail account?

Granola signs you in through a Google or Microsoft account or enterprise SSO, with no email-and-password option. As of November 2026, its help center says Gmail users may see a waitlist step while it finishes allowing Gmail accounts. Wispr Flow accepts Apple, Google, Microsoft, SSO or any email and password.

Does Wispr Notetaker work on iPhone and Android?

Yes. Wispr Notetaker runs on Mac, Windows, iPhone and Android. On your phone, it's part of the Wispr Flow app and records meetings through your phone's microphone, so if you already use Wispr Flow for dictation, Notetaker is in the app you have.

Can I move my Granola notes to Wispr Notetaker?

Yes. Wispr Notetaker imports Granola's CSV export, bringing over titles, dates, notes, summaries and transcript text. Speaker labels, audio and attendee lists don't come across.

Is Wispr Notetaker free?

Yes. Notetaker is included in Wispr Flow's free plan, with 50 recordings a week, AI tool access and dictation. Pro costs $12 per user per month billed annually, or $15 monthly.

Does Wispr Notetaker train AI models on my meetings?

On Free and Pro, a setting that lets Wispr Flow use your content to improve its models is on by default, and you can turn it off at any time. Training is disabled for every Enterprise account.

How do Wispr Notetaker and Granola handle security?

Wispr Flow encrypts your data in transit with TLS 1.2 or higher and at rest with AES-256, and recording happens on your own device with nothing joining the call. Its dictation service holds SOC 2 Type II and ISO 27001 certifications; Notetaker launched after those audit periods, so it wasn't part of them. Your content is never sold, and Wispr Flow's agreements bar its third-party AI providers from training on your data. Enterprise adds SSO, user provisioning, audit logs and managed deployment, and admins can set privacy rules that members can't override. Granola takes a different route with the most sensitive piece: it deletes meeting audio as soon as transcription finishes, so no recording exists, and its Enterprise plan adds SSO, org-wide training opt-out and transcript retention policies. For the full breakdown, read Is Wispr Flow safe?, or request Wispr Flow's audit reports through its Trust Center.

Which apps does Wispr Notetaker integrate with?

Wispr Notetaker connects to Google Calendar and Outlook Calendar, plus Slack, Gmail and Notion, which give it context for summaries, meeting chat and pre-meeting briefs. It detects calls in Zoom, Google Meet, Microsoft Teams, Webex and Slack huddles, and you can record any other app by starting a note yourself. Claude, ChatGPT, Codex, Gemini and Cursor connect in one click through MCP, and any other MCP tool can connect with a server URL; that access is read-only. You can also import past meetings from Granola and Otter, and admins can switch off individual connections for their organization.

Appendix: accuracy test methodology (November 2026)

Wispr Flow ran this test in November 2026 to compare the transcription accuracy of Wispr Notetaker and Granola on identical audio. The same rules applied to both tools.

Recording setup

  • Granola and Wispr Notetaker each ran on its own MacBook Air with the same audio capabilities.
  • Audio played from a third device placed at an equal distance from both laptops, so both tools recorded the same sound at the same time.
  • Each recording was tested once.

Source material and reference transcripts

The 13 recordings covered single narrators, interviews and fast multi-speaker exchanges. Each tool's transcript was compared against a transcript provided by the source:

  • Audiobooks and the children's story: The published text of each work, from Standard Ebooks, Project Gutenberg and American Literature. The audio came from commercial audiobook recordings, such as those from Simon & Schuster Audio and Blackstone Audio.
  • Podcasts: The official transcripts published by the CDC, Freakonomics Radio and This American Life. For the Vox Explain It to Me episode, the reference was the episode's production script.
  • Congressional hearing and Supreme Court arguments: The official transcripts published on congress.gov and by the Supreme Court.

How transcripts were compared

  1. The two tools' transcripts were aligned word by word against each other.
  2. Every place they disagreed was checked against the reference transcript.
  3. For audiobooks, each tool's transcript was also scored directly against the full book text.

What counted as an error

An error is a word a tool got wrong, added or left out compared with the reference transcript.

These differences were not counted:

  • Spellings of names, including people, places, companies, court cases and products
  • Numbers written as digits instead of words, such as "6" for "six"
  • British versus American spelling
  • Filler sounds such as "um" and "uh," stutters and restarted sentences
  • Contractions, such as "there's" for "there is"
  • Foreign-language passages, and dialogue a book spells phonetically to show an accent
  • Ads, and words missed because a recording started late

When both tools agreed against the source

If Granola and Wispr Notetaker independently wrote the same thing and the reference said something else, the speaker most likely said it the way both tools heard it. Those differences were counted against neither tool. For example, both tools wrote "in the Tuscan hills" where the book reads "on the Tuscan hills."

Checks against the audio

Reference transcripts are sometimes lightly edited. Where a tool's transcript differed from the reference in a way that suggested the reference had been cleaned up, the audio was replayed. In This American Life, Episode 856, the speaker said "in a woman's prison" and "the first couple lines," while the official transcript reads "women's" and "couple of lines." Wispr Notetaker matched the audio and was counted correct.

Meaningful errors vs. minor differences

Each error was sorted into one of two groups, based on whether a reader would come away with a wrong idea of what was said.

  • Meaningful errors: Wrong words that change the meaning, unreadable garble, invented content, and lines dropped or attributed in a way that changes who said what.
  • Minor differences: Small connecting words and fillers, tense, rephrasings that keep the meaning, and sound-alike words a reader would see through, such as "wrapped" for "rapped." These count toward total word errors but not meaningful errors.

Limitations

  • Small sample: The test covered 13 recordings, each tested once on one hardware setup.
  • No meeting app involved: Audio played aloud from a third device, so Granola's speaker tags, which read names from Google Meet, Zoom and Teams, couldn't apply.
  • Imperfect references: Published transcripts are often lightly edited, which is why the results separate meaningful errors from minor differences.
  • Judgment calls: Sorting errors into meaningful and minor required judgment, applied with the same rules to both tools.
  • Run by Wispr Flow: Wispr Flow designed and scored the test, applying the same rules to both tools.
