Otter vs Fathom vs Fireflies: Which AI Notetaker for a Sales Team?

Otter, Fathom, and Fireflies all do the core job — join your Zoom / Google Meet / Teams calls, record, transcribe, summarize — and all three do it well enough that feature-checklist comparisons mostly tie. This comparison uses the lens that actually separates them for a sales team: can your call data get out and feed the rest of your stack — your CRM, your coaching layer, your analytics?

We integrate with these tools rather than compete with them (Salescadia is the analysis layer that consumes their transcripts), so we have no recorder to sell you. Here's the honest read.

The 60-second version

• Fathom — free tier with unlimited recording and API access included. The easiest data-out story of the three. Best default for teams under ~20 reps.
• Fireflies — the most built-out team admin (channels, centralized controls). API requires the Business plan (~$19/user/mo). Best when RevOps owns a larger rollout.
• Otter — the most recognizable brand and a polished product, but the weakest data-out story: its new public API is Enterprise-only and in beta. Fine if you live inside Otter; limiting if you want your calls feeding other systems.

Pricing

• Otter: free Basic tier (limited minutes), Pro and Business tiers per user, Enterprise by sales contact.
• Fathom: genuinely free for individuals with unlimited recordings; paid tiers add advanced AI + team features.
• Fireflies: limited free tier; Pro ($10/user/mo) and Business ($19/user/mo) are the practical team tiers.

On pure recording value, Fathom's free tier is the outlier — unlimited recording at $0 is hard to argue with.

API access — the difference that compounds

This is the comparison most posts skip, and it's the one that determines whether your transcripts become an asset or a silo.

Why it matters: a transcript sitting inside a notetaker answers "what was said." It takes an analysis layer to answer the revenue questions — is every call coached, which rep needs help where, did the follow-up go out, is this call on the right CRM record. Those layers (ours included) can only consume what the recorder's API exposes. On one team we measured, the close-rate gap between the best and lowest rep was 30 points on identical leads (60.9% vs 30.6% across 2,420 meetings in the MedLeague case study) — a gap you can only coach against if something is scoring every call.

With Fathom, that data-out path is available to literally every user. With Fireflies, it's a $19/user decision. With Otter, it's an enterprise procurement conversation.

Team features

• Fireflies leads: channels for organizing calls, centralized admin, org-wide settings. It feels built for a RevOps owner managing 30+ reps.
• Otter has solid workspace features on Business/Enterprise, and its brand recognition helps adoption.
• Fathom covers the essentials (team libraries, sharing). One caveat for integrations: its API keys are user-scoped, so team-wide coverage needs reps sharing recordings to the team.

Transcript quality for downstream analysis

All three transcribe accurately. For downstream tools, the differentiator is attribution metadata: Fathom pre-matches each utterance to a calendar invitee's email and flags which attendees are external — the most machine-usable speaker data of the three. Fireflies and Otter attribute by display name, which downstream tools must match heuristically.

Recommendations by situation

• Small team, want coaching on every call, minimal budget: Fathom. Free recording + one-click Salescadia integration on any plan.
• Mid-size team, RevOps-managed, channels matter: Fireflies Business. The Salescadia integration needs that tier anyway.
• Already on Otter and happy: stay for recording; get analysis by pasting your key calls into Salescadia — or if you're on Otter Enterprise, their new API makes an automatic integration possible and we're looking for a design partner to ship it.
• Torn between Fathom and Fireflies specifically: we wrote a dedicated head-to-head.
