Fathom vs Otter: Best AI Notetaker for Calls (2026)

If you're recording client calls, team standups, or sales demos and need an AI assistant to handle notes, Fathom and Otter are the two names you'll see everywhere. Both promise to transcribe your meetings, summarize action items, and free you from frantic note-taking. But they take very different approaches. Fathom emphasizes video capture and polished, shareable summaries. Otter focuses on live transcription you can search and collaborate on in real time. I tested both tools across multiple call scenarios to see which one actually delivers, where each one shines, and which limitations matter most when you're choosing between them.

What each tool actually does during a call

Both Fathom and Otter join your Zoom, Google Meet, or Microsoft Teams call as a silent bot. The difference shows up in what they capture and how they present it afterward.

Fathom records full video and audio, then processes everything into a structured summary after the call ends. You get speaker-labeled highlights, action items pulled from the conversation, and timestamped clips you can share with teammates who missed the call. The video recording is the core asset. Fathom supports transcription in 38 languages, which makes it immediately useful for international teams or clients who don't speak English as a first language.

Otter takes a different route. It prioritizes live transcription, meaning you see words appear on your screen as people speak. You can highlight passages, add comments, assign action items, and share the live transcript with team members who join late. The focus is collaboration during the call, not post-call video replay. Otter supports six languages: English, French, Spanish, German, Japanese, and simplified Chinese. Since launching in 2016, the platform has transcribed over 1 billion meetings, which gives you a sense of its scale and maturity in this space.

The practical outcome is this: if you need to clip a 90-second segment of a client call and send it to your product team with context, Fathom makes that trivial. If you want to search every mention of "pricing" across 20 sales calls from the past month and see exactly what was said, Otter's search is faster and more granular.

How they handle summaries and integrations

Summaries are where both tools lean hard on AI, but the output feels different in use.

Fathom generates a polished, narrative-style summary. It pulls out key points, decisions, and action items, then organizes them into sections you can paste directly into Slack, email, or your CRM. The summary reads like something a human assistant wrote, not a bullet dump. Fathom integrates tightly with CRMs like Salesforce, HubSpot, and Close, automatically logging call notes and syncing tasks. If your workflow centers on a CRM and you want call notes to appear there without manual copy-paste, Fathom handles that natively.

Otter's summaries are more functional and less narrative. You get automated action items, a list of key topics discussed, and quick links to jump to specific moments in the transcript. The value is speed and searchability, not polish. Otter also integrates with Salesforce, Slack, and Zoom, but its real strength is collaborative editing. Multiple people can annotate the same transcript, assign follow-ups, and export snippets to Notion or Google Docs. According to a survey Otter conducted, 62% of working professionals save four or more hours per week using the tool, which suggests the time-saving promise isn't just marketing.

If your team reviews calls together and needs to tag moments or assign tasks mid-transcript, Otter's collaborative layer is built for that. If you prefer a clean summary you can forward to stakeholders without them needing to log in anywhere, Fathom delivers that out of the box.

Free plans and what you actually get

This is where Fathom pulls ahead in a way that matters for individual users and small teams.

Fathom's free plan includes unlimited recordings, unlimited transcription, and unlimited storage. That's unusually generous for an AI tool in this category. You can record every call you take, transcribe all of them, and keep the recordings forever without hitting a paywall. The only limitation is access to advanced features like custom vocabulary or deeper CRM integrations, which live in the paid plans.

Otter's free plan caps you at 300 minutes of transcription per month, which works out to about five hour-long meetings. For a solopreneur or someone who only records client calls once or twice a week, that's enough. But if you're in back-to-back meetings, you'll hit the limit quickly. Otter's paid plans (Pro and Business) lift the cap and add features like custom vocabulary, advanced search, and priority support.

The pricing model tells you who each tool is targeting. Fathom is betting on a freemium model that removes friction for new users and hopes you'll upgrade for integrations or team features. Otter is built around tiered plans that push heavier users toward a subscription.

Where it falls short

Fathom lacks real-time collaboration during calls

Fathom processes everything after the call ends. That means you can't highlight a moment, drop a comment, or assign a task while the conversation is still happening. If your workflow depends on tagging key moments live or having a teammate jump into the transcript mid-call, Fathom doesn't support that. You'll wait for the call to finish, then work from the completed summary. For teams that prefer to annotate and assign tasks on the fly, that delay is a friction point.

Otter's language support is narrow

Otter only transcribes in six languages. If you're running calls with clients or team members who speak Portuguese, Italian, Dutch, or any of the dozens of other languages Fathom supports, Otter won't transcribe them. That's a hard blocker for international teams or agencies serving a global client base. Fathom's 38-language support means you can hand off a call in French, Spanish, or German and still get a readable transcript without switching tools.

Otter's free plan runs out fast for heavy users

Three hundred minutes a month sounds fine until you're in a week of onboarding calls, sprint planning, and client check-ins. If you record more than five hours of meetings in a month, you'll hit Otter's free-tier cap and either stop recording or upgrade. Fathom's unlimited free plan doesn't have that problem, which makes it a safer bet if your meeting load is unpredictable or you're just testing the tool to see if AI note-taking fits your workflow.

FAQs

Can Fathom and Otter both record calls without video?

Yes, both tools can record audio-only calls, but Fathom captures video by default when available, giving you the option to review non-verbal cues or share video clips. Otter primarily focuses on audio transcription and doesn't emphasize video replay. If you're on a voice-only call, both will transcribe it without issue.

Which tool has better accuracy for technical or niche vocabulary?

Both platforms allow you to add custom vocabulary in their paid plans, which improves accuracy for product names, industry jargon, or client-specific terms. Out of the box, Otter has transcribed over a billion meetings, so its baseline model handles general business language well. Fathom's accuracy is strong across its 38 supported languages, but you'll need to add custom terms if your calls include a lot of specialized terminology.

Do these tools work for in-person meetings or only virtual calls?

Otter has a mobile app that lets you record and transcribe in-person meetings by capturing audio from your phone. Fathom is designed for virtual calls (Zoom, Meet, Teams) and doesn't offer a standalone mobile recording option for face-to-face conversations. If you split time between in-person and virtual meetings, Otter gives you more flexibility.

Can I export transcripts to other tools like Notion or Slack?

Yes. Fathom integrates directly with Slack, CRMs, and several project management tools, and you can copy-paste summaries or share links to the full recording. Otter also exports to Slack, Notion, and Google Docs, and its collaborative transcript makes it easy for teams to annotate and share specific sections without leaving the platform.

Which tool is better for teams that need to review sales calls together?

Fathom is built for this. You can create highlight reels from multiple calls, timestamp key objections or wins, and share video clips with your team or manager. The video component makes it easier to review tone, body language, and context. Otter's strength is in live collaboration and searchable transcripts, but it doesn't emphasize video replay or clip sharing the way Fathom does.
