Pick Fathom (Free) if you're on Zoom, speak English, and want unlimited recording with zero cost
Pick Otter.ai (Free–$30/month) if you need real-time live captions during meetings, collaborative note-taking, or support for Google Meet and Microsoft Teams on the free plan (Fathom's free tier is Zoom-only)
Both are honest meeting recorders, neither does pre-meeting briefing, post-meeting follow-up email drafting, or action-item tracking into a task system. That's a different tool category (alfred_ for the post-meeting workflow layer, not a replacement for either)
Language coverage: Otter supports ~3 languages (English, Spanish, French); Fathom supports 38. For truly multilingual teams, Happy Scribe (150+ languages) outperforms both
Price asymmetry: Fathom is free forever for individual Zoom users with unlimited recording, a rare genuinely-unlimited free tier. Otter's free tier caps at 300 minutes/month, which is ~5-6 meetings before you hit the wall
The decision splits cleanly by platform: Zoom-only + English = Fathom every time on cost alone. Multi-platform (Meet/Teams) or need for real-time live captions = Otter. The edge cases where you'd pay for Otter Pro instead of using Fathom free: you need live captions during the meeting (Fathom doesn't do this), you're on Google Meet or Teams primarily, or you need collaborative annotation during the call.
The short answer: if you’re on Zoom and speak English, Fathom: free, unlimited, no storage cap. If you need Google Meet or Teams coverage, real-time live captions, or heavier collaborative note-taking, Otter.ai. The decision is usually that simple.
This post walks through the specific scenarios where each wins, the free-tier comparison (where most people actually land), and the honest overlap with workflow tools like alfred_ that aren’t meeting recorders at all.

Both tools cover the core meeting-recorder job well. The meaningful differences are platform coverage (free tier), live captions (Otter only), and file transcription (Otter only).
When Fathom Wins
You’re on Zoom, Fathom’s free tier is unlimited on Zoom. Nothing else matches this.
You speak English, 38 language support sounds good but English is the primary use case; for multilingual work look at Happy Scribe.
You don’t need real-time captions, most post-meeting transcription use cases don’t.
Your meeting volume is heavy, 300 min/month Otter cap is ~5-6 one-hour meetings. Fathom is unlimited.
Solo or small-team use, team features are better on Otter, but for individuals Fathom costs less.
When Otter.ai Wins
You’re primarily on Google Meet or Microsoft Teams, Otter free covers both; Fathom free doesn’t.
You need real-time live captions during calls, accessibility use case, or to read what’s being said in noisy environments. Otter is significantly better here.
You collaborate on notes live, multiple people annotating the transcript during the meeting. Otter supports this natively; Fathom doesn’t.
You need to transcribe uploaded audio/video, client interview recording, webinar, recorded phone call. Otter handles file uploads; Fathom only transcribes live.
You work on shorter meetings, 300 minutes covers ~10 half-hour meetings, which is plenty for many roles.
What Neither Does Well
Both tools are honest meeting recorders. Neither is designed for the broader post-meeting workflow:
Pre-meeting context briefs, neither assembles your email history + open commitments + prior meeting notes before a call
Action items → task system routing, both give you action items in the transcript; neither automatically routes them to Todoist, Asana, or alfred_’s task list
Follow-up email tracking. They can draft the follow-up; neither tracks whether you actually sent it
Cross-meeting pattern detection, if the same client asks the same question across three meetings, neither flags it
This is where alfred_ sits, not as a meeting recorder replacement, but as the pre/post-meeting workflow layer that sits alongside whichever recorder you pick. alfred_ does not record meetings. It handles the email and task layer around them. For comprehensive meeting workflow, the common pattern is Fathom OR Otter for the meeting itself, plus alfred_ for what happens before and after.
The Honest Multilingual Caveat
Both Fathom and Otter are English-first products. If you work across languages, a German team with French-speaking clients, for instance, neither tool handles non-English meetings well enough for reliable use. Happy Scribe (free tier available, Pro from $19/month billed annually) covers 150+ languages at 95%+ accuracy and is the correct tool if language coverage is your bottleneck. This post assumes English-primary use.
Bottom Line
Zoom + English + free → Fathom
Multi-platform + free → Otter
Real-time captions → Otter
Multilingual → Happy Scribe (neither)
Post-meeting workflow (not recording) → alfred_ + your recorder of choice
The choice between Fathom and Otter shouldn’t feel hard. Platform + cost + feature-gap (live captions, file transcription) determines it in under a minute.
Keep client work from slipping through the cracks
alfred_ is an AI assistant for client-facing teams. Each teammate gets help with email, calendar, replies and follow-ups.
Yes, for individual Zoom users with unlimited recordings and no storage caps. This is one of the most genuinely generous free tiers in the meeting AI space. Fathom makes money on their paid tiers: Premium ($20/user/month monthly, $16 annual) for individuals, plus Team ($19/user/month) and Business ($34/user/month monthly, $25 annual) above it, which add Google Meet and Microsoft Teams support, team sharing, and CRM integrations. But for solo Zoom users, the free tier has no artificial limits designed to force an upgrade.
What's Otter.ai's free tier limit?
300 minutes/month of transcription on the free plan, with a 30-minute cap per conversation, across Zoom, Google Meet, and Microsoft Teams. That works out to ~5-6 one-hour meetings/month. If your meeting load is heavier, Pro is $8.33/month (annual) for 1,200 minutes, and Business is $20/user/month for unlimited. Otter's advantage is the multi-platform coverage on free, Fathom free is Zoom-only.
Which has better transcription accuracy?
Both are strong for clear English speech. Fathom's accuracy is comparable to Otter on Zoom-quality audio. Otter has a slight edge on heavily accented English and spontaneous cross-talk. Neither handles non-English languages as well as Happy Scribe (150+ languages at 95%+ accuracy). Industry reviewers consistently rate both at 85-90% word accuracy for clean audio, which is the functional floor for useful meeting notes.
Does Fathom work with Google Meet or Microsoft Teams?
Only on paid plans (Premium $20/user/month, Team $19/user/month, or Business $34/user/month). The free tier is Zoom-only. This is the biggest gap for free users. If you're primarily on Meet or Teams, Otter's free 300 minutes covers you without a paid plan, making Otter the better free choice for non-Zoom platforms.
Does either tool draft post-meeting follow-up emails?
Fathom's paid plans include basic follow-up drafting from transcripts. Otter's AI Meeting GenAI features include summary + follow-up templates. Both are adequate for simple follow-ups. For complete post-meeting workflow (follow-up email drafted in your voice, action items routed to your task list, calendar prep for the next meeting), you need a workflow tool like alfred_ that sits alongside whichever recorder you pick. alfred_ is NOT a meeting recorder, don't substitute.
Can I use Fathom and Otter together?
Technically yes but it's rarely useful, you'd be recording the same meetings twice. Better pattern: pick the one that fits your primary meeting platform, and consider a separate workflow tool (alfred_) for what happens between meetings. The honest use case for running both is transition periods (evaluating Otter while Fathom is already installed) or platform-split situations (Fathom for Zoom, Otter for occasional Meet calls), neither is common.
What about privacy, who's recording what?
Both join meetings as visible bot participants by default. All standard jurisdictions require meeting participants to consent to recording. Both tools display the bot in the participant list and announce recording at the start. For meetings where a visible bot is inappropriate (sensitive client calls, regulated industries), Granola ($14/user/month) runs bot-free by capturing system audio locally. Fathom and Otter are bot-based only.
