Otter.ai vs Fireflies.ai vs Fathom: Real AI Meeting Assistant Cost for a Team in 2026
"Unlimited" is doing a lot of work on all three of these pricing pages, and it means three different things. Otter's Business tier is unlimited live meeting minutes but caps imported files at 6,000 minutes a user. Fireflies markets unlimited summaries but meters its advanced AI features (AskFred, advanced summaries, action items) through a monthly credit pool as small as 20 credits on its entry paid tier. Fathom's free plan is genuinely unlimited recording but caps advanced AI summaries at 5 calls a month. None of the three is lying, but none of the three is describing a single, comparable thing either.
The short answer
At team sizes of 5, 25, and 100, Fathom is the cheapest paid option on a like-for-like annual basis — its Team tier at $15/user/month (annual, 2-seat minimum) undercuts Fireflies Business ($19/user/month) and Otter Business ($19.99/user/month). But Fathom's cheaper Team tier lacks CRM field sync and coaching analytics, which sit behind its pricier Business tier at $25/user/month — at which point Fathom is no longer the cheapest of the three. Fireflies' AI credit system is the sharpest hidden constraint: Pro includes only 20 AI credits a month, shared or per-seat depending on plan, and a single meeting can consume several credits across one summary, one AskFred query, and one set of action items, meaning "unlimited transcription" and "unlimited AI features" are not the same claim.
What each vendor actually publishes
| Otter.ai | Fireflies.ai | Fathom | |
|---|---|---|---|
| Free tier | Basic: 300 transcription minutes/month, 30-minute per-conversation cap, 3 lifetime file imports | Free: unlimited recording, 800 minutes of storage, limited AI credits | Free: unlimited recording and transcription; advanced AI summaries capped at 5 calls/month |
| Entry paid (individual) | Pro: $16.99/month, or $8.33/month annual; 1,200 minutes/month, 90-minute conversation cap, 10 file imports/month | Pro: $18/month, or $10/month annual; 8,000 minutes storage/seat, 20 AI credits/month | Premium: $20/month, or $16/month annual; unlimited AI summaries, individual only, no team billing |
| Team tier | Business: $30/month, or $19.99/month annual (5-seat minimum reported); unlimited live meeting transcription, 6,000 imported-file minutes/user, 4-hour conversation cap, up to 3 concurrent meetings | Business: $29/month, or $19/month annual; unlimited storage, video recording, 30 AI credits/month, conversation intelligence and team analytics | Team: $19/month, or $15/month annual (2-seat minimum); shared library, keyword alerts, team-wide search |

| API access | Enterprise plan only | All plans, gated by request-rate limit | Not itemized as a distinctly priced tier in available sources |
| Metered AI feature | Not itemized as a separate credit system — AI Chat is included per plan tier | AI credits: 20 (Pro), 30 (Business), 50 (Enterprise), shared across the workspace, not per-user; overage reported at roughly $0.10/credit | Advanced AI summaries: unlimited on all paid tiers; only the free tier is capped at 5 calls/month |
Cost at three team sizes
Using each vendor's team-appropriate tier at annual billing, and each vendor's own published seat minimum where one exists:
| Team size | Otter Business ($19.99/user, 5-seat min) | Fireflies Business ($19/user) | Fathom Team ($15/user, 2-seat min) |
|---|---|---|---|
| 5 users | $99.95/month | $95/month | $75/month |
| 25 users | $499.75/month | $475/month | $375/month |
| 100 users | $1,999/month | $1,900/month | $1,500/month |
Fathom's Team tier is consistently the cheapest of the three at every size modeled — but Team lacks the CRM sync and coaching features that make Otter's and Fireflies' comparable tiers useful for a sales organization specifically. Fathom's Business tier, the feature-equivalent comparison, runs $25/user/month annual — $625/month at 25 users, above both Fireflies Business ($475) and roughly on par with Otter Business ($499.75).
Cost per active user, not per seat
Not every licensed seat actually records meetings every month. If, illustratively, only 60% of a team's seats are active recorders in a given month, the effective cost per meeting-recording user rises by roughly two-thirds above the per-seat sticker price: a $19.99/seat Otter Business license effectively costs $33.32 per person who actually uses it, once the 40% of seats sitting idle are folded into the real cost. This ratio holds regardless of team size, since it's driven by adoption rate, not headcount — meaning the more important number to model before buying seats for the whole company is realistic usage, not org-chart headcount.
What "unlimited" doesn't cover
Otter's unlimited claim is specifically about live, in-app meeting transcription — it does not apply to imported audio or video files, which are capped at 6,000 minutes per user per month on Business. A team that regularly uploads pre-recorded interviews, webinars, or external calls rather than joining them live will hit this cap in a way the "unlimited" marketing doesn't anticipate.
Fireflies' unlimited claim covers basic summaries only. The genuinely metered layer — AskFred conversational queries, advanced summary templates, and generated action items — draws from a shared monthly credit pool that starts at just 20 credits on Pro. A team running AskFred queries across dozens of meetings a week will exhaust this pool well before the month ends, at which point those specific features stop working until the next billing cycle or until additional credits are purchased at a reported ~$0.10 each.
Fathom's free-tier unlimited applies to recording and transcription, not to the AI summaries that make the transcript actually useful. Five advanced summaries a month is a real constraint for anyone attending more than about one meeting a week who wants an AI-generated summary rather than a raw transcript.
Not every seat needs the same plan
A common, avoidable cost is putting an entire team on the top tier when only a subset genuinely needs its features. A sales team using Fathom specifically for CRM field sync and coaching metrics needs Business ($25/user, annual); an internal operations team on the same Fathom workspace that just wants searchable meeting notes is fully served by Team ($15/user, annual) — a $10/user/month gap that a blanket single-tier rollout wastes entirely on the second group. The same logic applies to Fireflies: a team lead running frequent AskFred queries needs meaningfully more of the 20–30-credit pool than an individual contributor who mostly just wants a transcript.
Break-even: Business versus Team-tier features
Fathom's jump from Team ($15/user, annual) to Business ($25/user, annual) costs an additional $10/user/month for CRM field sync, deal view, and coaching metrics. For a sales organization, this pays for itself if CRM sync alone saves each rep more than roughly 15–20 minutes a month of manual note entry at a typical loaded hourly rate — a low bar that most active sales teams clear, making Business the more defensible choice specifically for revenue teams despite its higher per-seat cost.
Which platform fits which team
- A cost-sensitive team wanting straightforward transcription and summaries, no deep CRM needs: Fathom Team, the cheapest per-seat option at every size modeled.
- A sales or customer-success organization needing CRM field sync and coaching analytics: Fathom Business or Fireflies Business, priced closely against each other, with the deciding factor more likely to be integration depth with the specific CRM in use than the roughly $6/user/month gap between them.
- A team relying heavily on searchable meeting archives and cross-meeting AI search across a large historical corpus: Otter, whose core positioning and file-import allowances are built around this specific use case.
- A team planning to make heavy use of conversational AI queries against meeting content specifically: budget past Fireflies' entry-tier 20–30 credit pool explicitly, since this is the feature most likely to be under-provisioned by a default seat count.
Limitations and uncertainty
Otter's, Fireflies', and Fathom's published tier prices, seat minimums, and feature inclusions are confirmed directly from each vendor's own pricing page as summarized across multiple current sources. Fireflies' AI credit overage rate (~$0.10/credit) is reported by third-party sources rather than confirmed on Fireflies' own pricing page. One source describes a Fireflies Business price increase to $39/month that conflicts with the more consistently reported $19–29/month figure used throughout this article and used elsewhere for Enterprise; this article treats that specific claim as unreliable given the weight of contrary sourcing. The 60% active-usage assumption used in the cost-per-active-user calculation is an illustrative assumption, not a vendor-reported adoption statistic.
