Fathom vs Otter.ai (2026): The Free Plan Decides It

Start with the numbers, because they decide this comparison for most people.

Fathom's free plan includes unlimited meeting recordings, transcription, and core AI summaries. There is no monthly minute counter. A consultant running six calls a day pays nothing, forever — fathom.ai states the no-cap policy explicitly. Its paid plans add features rather than lift limits: Premium ($20/month) adds AI action items and follow-up emails, and Team and Business add collaboration and CRM field sync. Fathom became part of Superhuman in September 2026 and says nothing changes for users.

Otter's free plan includes 300 transcription minutes per month, capped at 30 minutes per conversation, plus three lifetime file imports — current limits are on the official pricing page. Three hundred minutes sounds generous until you map it to a real calendar: five one-hour meetings, and a week-and-a-half of a busy schedule consumes the entire month's allowance. The Pro plan at $16.99/month raises the caps substantially.

This is a deliberate strategy difference, not an accident. Fathom monetises teams and gives individuals the product free; Otter monetises individuals who outgrow a trial-sized free tier. Neither is wrong — but if you are an individual deciding where your meeting notes should live, one of these free plans covers you completely and the other runs out mid-month.

Both tools join Zoom, Google Meet, and Microsoft Teams calls as a visible bot participant, and the usual recording-consent obligations apply in both cases — the Fathom review covers the etiquette and legal side in more detail.

Otter is not just a capped Fathom — it does three things Fathom does not attempt.

Live transcription is the headline. During a meeting, Otter's transcript scrolls in real time, and participants can read along, highlight moments, and drop comments as the conversation happens. For accessibility (following a fast meeting in a second language, hearing-impaired participants), for journalists in interviews, and for anyone who wants to mark "that quote, right there" in the moment, this is the feature that matters — and Fathom has nothing like it. Fathom's marked moments exist, but the transcript itself arrives after the call.

File uploads are the second. Otter transcribes pre-recorded audio and video — phone interviews, voice memos, webinar recordings. Fathom processes only live meetings it attends as a participant; hand it an MP3 and there is nothing it can do. If your work involves recorded material and not just calendar meetings, Otter is the only one of the two in the running (though for heavy file-transcription workflows, Descript does that job with an editor attached — see the full transcription tools guide).

Search is the third, quieter advantage. Otter's archive search — every word of every meeting, filterable by speaker and date — is more mature than Fathom's. If the value you want is "a searchable record of everything said in a year of meetings", Otter's transcript-first design shows.

If the deliverable is a summary someone actually reads, Fathom produces the better one. Its summaries arrive within minutes of the call ending, structured into topics and decisions (AI action items, accurate enough to paste into a task manager, are on Premium). Otter's summaries are competent but consistently need more editing — its architecture centres the transcript, with the summary as a layer on top, and it reads that way.

Fathom's highlight clips deserve a specific mention because nothing else in the category does them as well: mark a moment during the call, and afterwards you get a shareable video snippet of exactly that exchange. "Here's the 90 seconds where the client explained the requirement" lands very differently in Slack than a paragraph of notes. For customer-facing teams, this quietly becomes the most-used feature.

Transcription accuracy on clear English is comparable — both sit in the same band, good enough for reference and search, short of verbatim-quote reliability. Accents, crosstalk, and bad audio degrade both similarly. Neither has a meaningful edge here, which is why the comparison gets decided by everything around the transcript.

One workflow note: Fathom includes basic HubSpot and Salesforce sync even on its free plan (up to three users per domain), while automatic record updates need its Business plan at $34/user. If CRM logging at the lowest price is the requirement, look at Fireflies at $10/month, which undercuts both, as covered in the Fireflies vs Otter comparison.

Choose Fathom if you are an individual who wants meeting notes handled automatically and completely free. Unlimited recordings, the category's best summaries, and highlight clips — with the only real limitations being no file uploads and no live transcript. For most solo professionals, this is the correct default, and switching costs nothing to verify.

Choose Otter.ai if the live transcript matters to how you work — accessibility, interviews, marking moments in real time — or if you need to transcribe uploaded recordings, which Fathom cannot do at all. Its Pro plan at $16.99/month is the price of making those capabilities your daily infrastructure.

If you are choosing for a team rather than for yourself, the calculus shifts toward CRM integrations and per-seat pricing — Fireflies at $10/user/month is the strongest team option and gets its own comparison against Otter. And if your recordings are content (podcasts, videos) rather than meetings, skip both for Descript, where transcription comes with the editor you will need anyway.
