Otter.ai vs Fireflies.ai vs Fathom: AI Meeting Notetakers Compared

Before picking a notetaker in this category, it's worth knowing that Otter.ai is defending an active federal class action alleging its bot records and transcribes meetings without all participants' consent, in violation of wiretap and privacy laws in several US states. A judge allowed most of the core claims to proceed in August 2026 — this is an ongoing, unresolved case, not a settled finding of wrongdoing, but it reflects a legal-scrutiny climate affecting the whole AI-notetaker category, not Otter alone. Fathom's new bot-free capture mode is a direct product response to this same industry-wide concern.

All three do the same core job — join a meeting, transcribe it, and summarise it — but differ on price, CRM depth, and extra features. Otter has the longest track record and the deepest CRM/sales integration. Fireflies adds a distinctive live-web-search feature during meetings at a lower price point than Otter's equivalent tier. Fathom has historically had the strongest free tier of the three and has been adding coaching and automation features while rebranding its domain from fathom.video to fathom.ai.

Otter's dedicated "Otter for Sales" product, with direct CRM sync to Salesforce and HubSpot, is the most mature sales-specific offering of the three, backed by the longest operating history in the category.

Fireflies' "Talk to Fireflies" feature — querying live web search during or about a meeting, powered by Perplexity — is a genuinely distinctive capability neither Otter nor Fathom currently offers, and its entry pricing undercuts Otter's equivalent tier.

Fathom's free tier has historically been the most generous of the three, with unlimited recording even for free users, and its new bot-free capture mode is a meaningful privacy-forward differentiator given the industry's current legal climate. Note its Premium price rose in March 2026, so check current pricing before assuming it's still the cheapest option.

Otter's Pro tier is the cheapest of the three at around $8.33/month annually, Fireflies is close behind around $10/month, and Fathom's Premium sits a bit higher around $16/month following its 2026 price increase — though Fathom's free tier remains the most usable of the three if paid features aren't a priority.

For deep CRM integration and a mature sales workflow, Otter.ai remains the safe, established choice. For a distinctive live-research feature at a lower price, Fireflies.ai is worth a look. For the strongest free tier and a privacy-conscious bot-free option, Fathom is the most compelling if budget or the industry's consent concerns are a priority.
