Fathom and Otter are both AI meeting transcription tools, but they’ve developed distinct identities. Fathom is a meeting notetaker built around highlights and action items. Otter is a transcription-first tool that also handles meeting summaries and integrates with a wider set of platforms.

Quick verdict

Choose Fathom if you primarily use Zoom and want the cleanest meeting summary and highlight experience. Choose Otter if you need broader platform support or a free tier with more generous transcription minutes.

Key differences

• Meeting highlights: Fathom lets you bookmark key moments during a call with a single click, which then appear in the summary. Otter’s highlighting is more manual post-meeting.
• Platform support: Fathom is primarily built for Zoom with Google Meet and Teams support. Otter works across Zoom, Google Meet, Microsoft Teams, and Webex.
• Summary quality: Both produce AI summaries with action items. Fathom’s summaries are generally tighter and more actionable. Otter’s are more verbatim-heavy.
• Free tier: Otter’s free plan offers 300 minutes/month. Fathom’s free plan is genuinely unlimited for Zoom meetings — a significant advantage.
• Team features: Both offer team plans with shared transcripts. Fathom’s team workspace is newer; Otter’s has been around longer and has more admin controls.

When to use Fathom

• Most of your meetings are on Zoom
• You want clean, concise AI summaries with action items
• You want a genuinely free unlimited tier without minutes caps
• You value the real-time highlight feature during calls

When to use Otter

• Your team uses multiple video platforms beyond Zoom
• You need longer verbatim transcripts for compliance or reference
• You want to search across a large archive of meeting transcripts
• You need OtterPilot integrations with HubSpot or Salesforce

Bottom line

For most operators using Zoom as their primary meeting tool, Fathom is the better experience — especially since it’s free with no meaningful limits. Otter is the right call if you need cross-platform coverage or a mature team admin setup. Try Fathom first; switch to Otter only if you hit a gap it can’t fill.
