TL;DR: Choose Fathom if you want the best free plan in the category — unlimited recordings, transcriptions, and storage, with a clean, simple interface built for individuals and small teams (paid from $19/month). Choose Fireflies if you need conversation intelligence at scale — 100+ languages, the "Ask Fred" AI copilot to query your entire meeting history, sentiment and topic tracking, and deep CRM integrations (paid from $18/user/month). But here's the catch for anyone doing customer research: both are meeting notetakers, not research tools. They transcribe conversations you already have — they don't recruit participants, ask adaptive research questions, or theme dozens of interviews into an insight report. Koji does. It starts free, then €29/month.

The AI notetaker boom — and its blind spot
AI meeting assistants exploded because they solve a real, painful problem: nobody wants to type notes during a call. And they're good at it. But there's a structural blind spot when teams try to stretch a notetaker into a research tool. A notetaker is reactive — it captures whatever happens to be said in a meeting you scheduled for another reason. Customer research is proactive — you decide the questions, probe the interesting answers, and compare patterns across many conversations. That gap is why the Fathom-vs-Fireflies debate misses the bigger question for researchers. More on the distinction in AI notetakers for user research.
Fathom: the best free plan, beautifully simple
Fathom's headline is generosity. Its free plan includes unlimited recordings, transcriptions, and storage — no minute caps — plus five AI summaries a month. Paid plans start at $19/month for individuals, adding 14 AI summary templates, automatic follow-up emails, and action items on every call. It supports 38 languages and is widely praised for a clean, low-friction interface.
Strengths: unbeatable free tier, simple UX, fast summaries, great for solo operators and small teams. Limits: lighter on cross-meeting conversation intelligence and advanced search; built around individual calls, not a searchable knowledge base of hundreds of conversations.
Fireflies: conversation intelligence for bigger teams
Fireflies trades Fathom's simplicity for depth. Its free plan caps you at 800 minutes of cumulative storage, and paid tiers run $18 (Pro), $29 (Business), and $39/user/month (Enterprise) — with video recording and unlimited storage gated to higher plans. What you get in return: 100+ languages, the Ask Fred copilot that answers natural-language questions across your entire meeting history, plus sentiment analysis, topic tracking, speaker analytics, and strong CRM integrations.
Strengths: deep conversation intelligence, cross-meeting search, sentiment/topic analytics, integrations for sales and RevOps. Limits: per-seat pricing scales up fast, the free plan is restrictive, and — like Fathom — it's optimized for internal meetings and sales calls, not structured research studies.
Fathom vs Fireflies: the quick verdict
- Pick Fathom if you're an individual or small team, you want a genuinely useful free plan, and simplicity beats configurability.
- Pick Fireflies if you run a larger team, live in your CRM, and need to query and analyze conversation data across hundreds of meetings.
For internal meetings and sales calls, that's the whole decision. For customer research, neither is the answer — and it's worth being clear about why.
The research layer both Fathom and Fireflies miss
Say you want to understand why customers churn, which feature to build next, or what they'll actually pay. A notetaker only helps if you've already booked and run the conversation yourself — and even then, it stops at a per-meeting summary. It won't:
- Recruit or reach participants. You still find and schedule everyone.
- Ask your research questions or probe adaptively. A notetaker records; it doesn't interview. It can't follow up on a surprising answer because it isn't driving the conversation.
- Theme across many interviews. Twenty call summaries are not a research finding. Someone still has to read all twenty, tag the patterns, and synthesize. See how to analyze customer interview data.
That's the layer Koji is built for. Koji is an AI-native customer research platform — not a notetaker — that runs the interview and the analysis:
- AI-moderated voice or text interviews. Koji's AI asks your questions and follows up in the moment, interviewing customers at scale on their own schedule with no notetaker sitting in a meeting. See /docs/ai-moderated-interviews and /docs/ai-voice-interviews.
- Six structured question types. Blend qualitative and quantitative in one study:
open_ended,scale,single_choice,multiple_choice,ranking, andyes_no— see /docs/structured-questions-guide. A notetaker can't ask a ranking question; it just listens. - Automatic thematic analysis. Koji themes every interview into a one-click report with quotes and sentiment — no manual reading, no moderator bias. See /docs/thematic-analysis-guide.
The difference is 10x faster insight and no research expertise required — question to finding in hours, not weeks. If you're comparing tools head-to-head, see Koji vs Fathom, Koji vs Fireflies, and Otter vs Fireflies.
The bottom line
Fathom wins on free-plan value and simplicity; Fireflies wins on conversation intelligence and scale. For capturing meetings and sales calls, pick whichever fits your team and budget. But if your goal is to understand customers — not just record a call you happened to be on — a notetaker is the wrong category. You need a tool that recruits, interviews, and analyzes. That's Koji: start free, then €29/month.
