Best privacy-focused AI notetaker for Windows in 2026
Wispr Notetaker is the best privacy-focused AI notetaker for Windows in 2026 for most people. It runs on Windows, records on your device so nothing joins the call, and keeps retention and model-training controls in your own settings. Granola, Otter.ai, and Fireflies.ai win specific privacy cases below.
How we compared these notetakers
We compared four tools on what a privacy-minded Windows user can check. How the tool gets into the meeting. What happens to the audio. Who sets transcript retention. Whether model training is a setting you hold. What an admin can enforce. Which certifications the vendor publishes.
Competitor facts come from each vendor's own pricing, security, privacy, help-center, and blog pages, read on September 14, 2026; prices are quoted as of that date. Wispr Notetaker's details are the ones we publish about our own product. Where a vendor states something in their words, that wording is kept rather than paraphrased into something tidier. Where a vendor says a feature is coming, it is listed as coming, not as shipped.
Quick picks for Windows in 2026
Windows is the deciding constraint for a lot of this. All four run on Windows 10 or later. What changes between them is how much of the privacy story you control yourself versus how much you ask an administrator or an account manager to configure for you.

What privacy actually means in a meeting notetaker
Most privacy pages answer a question nobody asked. The questions that matter in a meeting are narrower, and there are five of them.
- What joins the call, and what does everyone else in the meeting see
- What happens to the audio once the transcript exists
- Who sets how long transcripts live, you or someone else
- Whether your meetings are used to improve models, and whether that is a setting you can reach
- What an administrator can enforce for the whole organization
Some of those you control yourself. Others only an administrator can set. The first one, what the room sees, is the one people actually feel. A bot in the participant list is a notification to everyone on the call that the conversation is being captured, which is useful and also changes how people talk.
One thing worth separating out: recording without a bot changes what the meeting platform displays, not what you owe the people in the room. Tell everyone on the call you are recording, whichever tool you end up using.
Wispr Notetaker
Wispr Notetaker takes notes on the meeting you are in, on Windows, without anything joining the call. It works across Google Meet, Zoom, Microsoft Teams, Webex, and even a Slack huddle, because it captures on your device rather than sending a participant. It hands off cleanly between back-to-back meetings, notices ad-hoc calls that were never on your calendar, and ends on its own when the meeting does. Wispr Notetaker keeps a "get consent when transcribing others" notice in front of you the whole time it records.
On the data questions: meeting audio is encrypted and kept only temporarily to build your transcript, let you resume a meeting, verify quality, and troubleshoot, then it is automatically removed. Transcripts are yours to set, kept indefinitely by default or auto-deleted after 1, 7, 30, 90, 180, or 365 days. Deleting a meeting is permanent and applies across every signed-in device. Wispr Notetaker builds no voiceprints or biometric profiles of anyone on the call, and your content is never sold. Model training is a choice under a setting called "Improve the model for everyone", on by default for Flow Free and Pro, off by default for Enterprise, and changeable any time.
The tradeoff: Wispr Notetaker is not available on a BAA account, so if your Windows fleet handles protected health information, this is not the tool for that work yet. Mobile is on the roadmap, not shipped, and transcription covers 21 languages.
Granola
Granola takes notes without sending a bot, and it is popular with founders and investors. Word accuracy is its strong suit. On Windows it runs as a desktop app and captures your system's combined audio stream rather than joining the call.
Granola's audio is deleted from its systems once transcribed. Transcripts are kept indefinitely by default with an auto-deletion period you can set from a day to a year, per user, and workspace-wide on Enterprise. Data sits on US-hosted AWS, encrypted at rest and in transit. Anonymized data may be used to improve its models by default, with an opt-out on every plan and Enterprise opted out. Its transparency settings can post a chat notice into Meet, Zoom, or Teams, or show a watermark on your video while it transcribes, and Enterprise admins can require them.
The tradeoff: its docs ask you to have Granola open and be in a note, and to hit stop between back-to-back calls or the two meetings can land in one transcript. On the free Basic plan, notes older than 30 days are stored but not accessible in the app until you upgrade, and ISO 27001 is not currently available.
Otter.ai
Otter has been doing this the longest, and its default is a bot in the call. It is now selling mostly to sales teams. Its Otter Notetaker bot auto-joins Zoom, Google Meet, and Microsoft Teams by default. A bot-free desktop app is the secondary route. The Windows desktop app runs on Windows 10 or later, and its bot-free recording is opt-in per app, with "Remind me to record" as the stated default.
On governance, Otter is the most mature of the four. Enterprise gives you SAML SSO, directory sync, domain capture, enforced pre-recording emails to guests, custom retention, and the ability to disable external sharing, and Business adds activity logs. Several of those are switched on by your Otter account manager rather than by you. Deleted conversations sit in Trash for 30 days before permanent deletion, and a workspace retention policy is requested through that same account manager.
The tradeoff: Otter's privacy policy, effective June 16, 2026, says it trains its proprietary AI on de-identified audio recordings and on transcriptions, and no user-held training opt-out is published on its pages. Its free Basic plan stops a conversation at 30 minutes, allows 300 minutes a month, and keeps only your 25 most recent conversations (Otter pricing, September 2026).
Fireflies.ai
Fireflies sends a bot to the call and is built for sales and ops teams rolling it out across a lot of seats. Its Fireflies.ai Notetaker bot joins as a visible participant, and its bot-free modes label speakers generically and keep no audio or video. The desktop app runs on Windows 10 and later.
Fireflies states that meeting content, including audio, video, transcripts, and summaries, is never used to train any AI models, and names zero-retention agreements with its AI vendors. With Flow, training is a choice shown at onboarding and changeable any time in Settings. Storage is 256-bit AES at rest and TLS 1.2 in transit, US-hosted by default, and Enterprise can put storage in your own AWS or Google Cloud bucket in a region you pick. Workspace privacy defaults and record-restriction rules by keyword, email, or domain are available on every plan; SSO, SCIM, audit logs, and a rules engine sit on Enterprise.
The tradeoff: automatic retention windows, from one week to one year, are described as exclusive to Enterprise, so on other plans you delete meetings you own by hand. AskFred and other AI features run on monthly credits, and its billing docs say a paid user who runs out is automatically subscribed to the next higher credit tier, from 50 credits at $5 a month, renewing monthly unless paused. Downloading your own transcripts, summaries, and recordings needs Pro or higher.
Where each tool wins on privacy
No tool here wins every row, and the honest answer depends on which of the five questions matters most to you.
Read that bottom row carefully if you are in healthcare. Otter and Fireflies both offer a BAA on Enterprise today and Wispr Notetaker does not, so that segment belongs to them.
Choosing by what your Windows setup needs
If you want the fewest moving parts, pick the tool where the privacy controls are in your own settings rather than in a support ticket. Wispr Notetaker and Granola both put transcript retention and a training choice in the user's own settings rather than behind a support request. Otter's retention policy goes through an account manager, which is fine in a managed enterprise and slow if you are one person trying to lock something down this afternoon.
If an administrator has to prove what is happening across a whole Windows fleet, Otter and Fireflies have the longer governance lists, and Fireflies is unusual in offering record-restriction rules by domain on every plan. Wispr Notetaker is covered by SOC 2 Type II and ISO 27001 on every plan rather than behind an enterprise tier, which matters when procurement asks for a report and you do not want to buy a tier to get one.
If you want notes you can still use later in the week, that is the case for Wispr Notetaker: you can ask questions across every meeting you have kept and get an answer with a citation back to the source, and you can pull your transcripts and summaries into Claude, ChatGPT, or another compatible AI tool to write the follow-up. That connection exposes your Wispr Notetaker meetings, notes, summaries, and transcripts, and never your dictations. All of that is included on Flow Free. Try Wispr Notetaker for free.
Switching without losing your history
The usual reason people stay put is the archive. Coming from Granola or Otter, import into Wispr Notetaker is live, so your history comes with you. Coming from Fireflies, there is no import; the route is to connect both tools to Claude, where Fireflies' connection needs a paid Claude plan, and name both in the prompt so one chat searches your old archive and your new notes together.
Nothing here asks you to delete anything or cancel anything first. Run both notetakers on one real meeting, read the two transcripts and the two summaries side by side, and check the three things you actually care about: where the audio went, how long the transcript will live, and who can change that setting.
Healthcare work goes to Otter or Fireflies today. Everyone else on Windows should start with the tool whose retention switch is in their own settings. Record one meeting in Wispr Notetaker and check where the audio went.
Frequently asked questions
Does Wispr Notetaker work on Windows?
Yes. Wispr Notetaker runs on Windows 10 and 11, and takes notes on Google Meet, Zoom, Microsoft Teams, Webex, and Slack huddles without joining as a participant. It needs 16 GB of RAM and 2 GB of free storage, which is more than Wispr Flow dictation requires. iPhone and Android are on the roadmap.
Is there a free privacy-focused notetaker for Windows?
Flow Free includes Wispr Notetaker, with a weekly usage allowance, answers across your meetings with citations, Outlook and Google Calendar connections, use of your notes in Claude and ChatGPT, and the option to opt out of model training at any time. Quick recordings under five minutes do not count toward the weekly limit.
What does not come across when I import from Granola or Otter?
Import from Granola and from Otter brings your notes, summaries, and transcripts. It does not move your old tool's sharing settings, templates, or integrations, so anything you had wired up there has to be set up again in Wispr Notetaker. Fireflies has no import path. Ask about both archives from one AI assistant instead.
Is Wispr Notetaker HIPAA compliant?
No. HIPAA-ready is a Wispr Flow dictation claim and requires a signed BAA, which an individual can accept in Settings. Wispr Notetaker is not available on a BAA account, so it should not be used for protected health information. If HIPAA coverage for meeting notes is a requirement today, Otter and Fireflies offer a BAA on their Enterprise plans.
Do meeting participants know I'm recording?
Nothing joins the call, so the meeting looks normal and recording happens on your device. Wispr Notetaker keeps a "get consent when transcribing others" notice in front of you the whole time it records, and links out to guidance. Your organization can require you to confirm consent before recording starts, and you can add a Wispr Notetaker notice to your calendar invites.
Does Wispr Notetaker train AI models on my meetings?
You choose during onboarding, and you can change it at any time in Settings, under "Improve the model for everyone." The setting covers dictation and meetings together. On Enterprise it is off for everyone by default, and admins can enforce that org-wide alongside retention policy.
Can I delete my meeting transcripts?
Yes. You can delete any meeting, transcript, or note at any time, and deletion is permanent across every signed-in device, taking the notes, summary, and transcript with it. You can also set transcripts to auto-delete after 1, 7, 30, 90, 180, or 365 days, or keep them indefinitely, which is the default.
