# Fathom AI vs Otter.ai: Meeting Notes Compared

> Compares Fathom and Otter.ai on pricing, Slack integration, and search to help you pick the right AI meeting transcription and notes tool for your team.

_[Wortins Blog](https://www.wortins.com/blog) · Published Tuesday, August 25, 2026_

**Pick Fathom if your team already lives in Slack and wants instant AI summaries posted there with minimal friction. Pick Otter.ai if you need to search across a large archive of past meetings or prefer a strong iOS recording experience.** Both transcribe at over 95% accuracy and bill as monthly subscriptions rather than charging per recording, so the decision comes down to workflow fit rather than raw transcription quality.

## The short answer

Fathom's free tier already records and transcribes unlimited meetings, with Pro ($20/month) adding AI summaries and — its signature feature — direct Slack integration that pastes meeting summaries straight into your channels. That makes it a strong fit for teams that treat Slack as their communication hub. Otter.ai's free tier caps out at 600 minutes/month, with Pro at $20/month and Business at $30/month adding team features; its strength is deep searchability across past meetings and a well-built iOS app, which matters more once you've accumulated months of recordings and need to find something specific rather than just get today's summary.

## Comparison table

| Tool | Best for | Pricing | Key strength |
|---|---|---|---|
| Fathom | Slack-centric teams, instant summaries | Free (unlimited recording); Pro $20/mo | Direct Slack integration, fast summaries |
| Otter.ai | Search across meeting history, iOS | Free (600 min/mo); Pro $20/mo; Business $30/mo | Searchability and calendar integration |

## Fathom

Fathom's free tier is notably generous for a starting point — unlimited recording and transcription with no minute cap — and Pro at $20/month layers on AI summaries plus deep Slack integration, letting summaries land directly in the channels your team already checks. It's built around speed: getting a usable summary immediately after a call ends, rather than requiring you to dig through a searchable archive.

**Pros:** unlimited recording even on the free tier; fastest path from meeting end to shareable summary; Slack integration is deeper than Otter's.
**Cons:** less emphasis on searching across a large historical archive of meetings than Otter; no dedicated strength around iOS the way Otter has.
**Who it's for:** teams that coordinate primarily through Slack and want meeting takeaways to show up there automatically.

## Otter.ai

Otter.ai's free tier gives 600 minutes/month, with Pro at $20/month and Business at $30/month adding team-oriented features. Its differentiator is searchability — finding a specific moment or decision across a large volume of past meetings — plus calendar integration and a well-regarded iOS app for recording on the go.

**Pros:** strong search and recall across historical meetings; solid iOS app and calendar integration; Business tier scales for larger teams.
**Cons:** free tier's 600-minute cap is a real limit compared to Fathom's unlimited free recording; Slack integration isn't as central to its design.
**Who it's for:** professionals who need to search back through hundreds of meetings, or who record primarily from an iPhone.

## Pricing structure

The two tools also differ in how they gate value. Fathom's free plan removes the usual constraint entirely — unlimited recording and transcription with no minute cap — and reserves its Pro tier ($20/month) purely for AI summaries and Slack integration rather than for unlocking more recording time. Otter.ai takes the more conventional approach of a monthly minute allowance: 600 minutes free, then Pro ($20/month) and Business ($30/month) raising that ceiling along with adding team-oriented features. That distinction matters if your team simply has a high volume of meetings — Fathom's model means volume alone never forces an upgrade, while Otter's model means a busy month could push you past the free tier's 600 minutes even if you don't need any of Otter's paid features yet.

## How to choose

If your team's default communication channel is Slack and the main thing you want out of a meeting tool is "summary posted where we already talk," Fathom's free unlimited recording and Pro-tier Slack integration are purpose-built for that, and it costs nothing to test the free tier first. If your bigger pain point is not being able to find what was decided in a meeting from three months ago, Otter.ai's search strength is the more relevant feature, even though its free tier is capped at 600 minutes — a real constraint if your team has back-to-back calls all month. Neither charges per meeting length beyond those tiers, so cost predictability is similar once you're on a paid plan. Since both integrate with Zoom, Google Meet, and Microsoft Teams, the platform you meet on isn't the deciding factor — how you want to receive and later retrieve the output is.

Device and platform habits matter too. If your team records mostly from iPhones or relies on a well-integrated calendar view to see upcoming and past meetings side by side, Otter's iOS app and calendar integration are a real, if less headline-grabbing, advantage over Fathom. If your team is Slack-first and rarely opens a separate app to check meeting notes, Fathom's ability to push summaries directly into a channel removes a step that Otter doesn't eliminate — you'd still need to open Otter or copy a summary manually into Slack yourself. Neither gap is disqualifying, but it's worth mapping against how your team actually behaves after a call ends, since that's when a note-taking tool either gets used or gets ignored.
