THE SHORT ANSWER
If you are an individual or small team who wants the best free tier → Fathom
If you need live transcription and the lowest per-seat cost → Otter
If you need CRM sync and conversation intelligence for a sales team → Fireflies
If you are comparing these on transcription accuracy, stop — under clean audio all three land in the low-to-mid nineties and the differences are smaller than any review implies. The decisions that actually matter are cost per seat at your team size, what the free plan genuinely covers, and whether a named bot appearing in your meetings is acceptable to your clients.

Fathom — for individuals and the best free tier (free, ~$29/month for teams)
If you want AI meeting notes without paying anything, Fathom's free plan is the most generous in the category by a wide margin — unlimited recordings, unlimited transcriptions, and unlimited storage. The single catch is that advanced AI summaries are capped at five meetings per month, which matters if you run many customer interviews and matters very little if you take four calls a week. Fathom is also noticeably fast: summaries are often ready before the meeting ends, and the interface is cleaner and less cluttered than Fireflies. Time-to-value is its real advantage — install it, it joins your calls, it produces summaries, with almost nothing to configure. The limits are integrations and team pricing: fewer CRM connections than Fireflies, and a significant jump to roughly $29 per month for team features.
Otter — for live transcription at the lowest per-seat cost (~$8.33–10/user/month)
If your team co-edits notes during calls or you simply need the cheapest paid seat, Otter is the most affordable option here at roughly $8.33 to $10 per user per month on annual billing. It is also the only one of the three built around live streaming transcription rather than post-meeting processing, which suits teams that reference notes mid-conversation. Accuracy is marginally the best of the three under clean audio at around 93–95%, and Otter's SOC 2 certification with HIPAA compliance on Enterprise makes it viable for regulated industries. The constraints are the free tier and the higher tiers: 300 minutes per month with a 30-minute cap per conversation on free, and roughly $30 per user per month for the top team plan, which erodes the cost advantage at scale.
Fireflies — for sales teams that need CRM sync (~$10–19/user/month)
If meeting notes need to end up in your CRM without anyone typing, Fireflies is the one built for that. It is a conversation intelligence platform first — tracking topics across calls, analysing sentiment, measuring talk-time ratios, and syncing structured output into your sales stack. Pricing starts around $10 per user per month, with the Business tier at roughly $19 per user per month adding the CRM and coaching depth most sales orgs actually buy it for, plus 100+ language support. Its free tier is the most restrictive of the three at 800 minutes of total storage. Two honest caveats: setup takes real effort — budget one to two weeks to deploy properly — and per-seat cost climbs quickly across a large team when only some reps need the full tier.
When it actually pays off
| Your situation | Best fit | Why |
|---|---|---|
| Solo founder, a few calls a week | Fathom | Free, unlimited recordings, 5 AI summaries covers it |
| 10-person team, budget-sensitive | Otter | ~$8.33/user annual is the cheapest paid seat here |
| Sales team needing CRM automation | Fireflies | Only one with real conversation intelligence and CRM depth |
| Heavy interview volume, needs every summary | Otter or Fireflies | Fathom's 5-summary free cap becomes the bottleneck |
The pattern is clean. For individuals, Fathom is free and sufficient — there is no reason to pay. For a general team that needs broad meeting documentation without CRM automation, Otter's per-seat cost is genuinely lower and the difference compounds across ten or twenty seats. Fireflies only justifies its price and setup effort when the CRM sync and coaching analytics are being used; bought as a transcription tool, it is the most expensive way to do the same job the other two do.
What nobody else mentions
All three put a visible bot in your meeting. "Fathom Notetaker," "OtterPilot," and "Fireflies.ai Notetaker" each appear in the participant list, visible to everyone. As of March 2026, Google Meet flags third-party recording bots as a potential risk by default, which has changed how external participants perceive them in client-facing calls. Some participants self-censor when they know a bot is logging. If that matters for your sales or advisory conversations, bot-free alternatives that capture system audio directly are worth evaluating.
Free tiers here are not comparable products. Fathom gives unlimited recordings but caps AI summaries at five a month. Otter gives 300 minutes with a 30-minute per-conversation limit. Fireflies gives 800 minutes of total storage — not monthly, total. Three completely different constraints wearing the same word. Match the constraint to your actual meeting pattern before assuming "free" solves it.
Accuracy differences are smaller than the reviews suggest. Under clean audio with standard English accents, Otter leads at roughly 93–95%, Fathom sits at 92–95%, and Fireflies at 90–93%. In practice that gap is barely perceptible in typical professional meetings. Choosing on accuracy alone is optimising the variable that differs least.
Fireflies is a deployment, not an install. Fathom works out of the box in minutes. Fireflies requires configuration to unlock its actual value — CRM field mapping, topic trackers, coaching rules — and typically needs one to two weeks and someone who owns it. If nobody has that bandwidth, you will pay for a conversation intelligence platform and use it as an expensive transcriber.
FAQ
Which has the best free plan?
Fathom, clearly. Unlimited recordings, unlimited transcriptions, and unlimited storage, with the only meaningful limit being five AI summaries per month. Otter caps at 300 minutes monthly with a 30-minute per-conversation limit, and Fireflies limits you to 800 minutes of total storage rather than a monthly allowance.
Which is cheapest for a team?
Otter, at roughly $8.33 to $10 per user per month on annual billing. Fireflies starts around $10 and its Business tier is roughly $19. Fathom's team plan jumps to around $29 per month, which makes it the least economical of the three at team scale despite having the best free tier for individuals.
Do these tools work without a bot joining the meeting?
Not by default — all three join as a visible named participant. Fireflies offers some bot-free capture through its desktop app and the Google Meet SDK, but standard recording uses a visible bot. If bot-free recording is a requirement, tools that capture system audio locally are a different category worth evaluating separately.
Is Fireflies worth it over the cheaper options?
Only if you will use the CRM sync and conversation intelligence. Its real value is analysing patterns across dozens or hundreds of meetings, tracking customer feedback themes, and pushing structured data into your sales stack. If you just need accurate transcripts and summaries, Fathom or Otter do that for less money and less setup.
Your meeting notes are where decisions either get captured or get lost.
