Okay so here is my honest take after putting Otter, Fireflies, Fathom, and a couple of smaller players through real meetings, not demo meetings, actual client calls where things went sideways and people talked over each other.

The short version before I get into it:

Fathom is the one I kept. Otter gave me the most accurate transcript. Fireflies had the best CRM integrations. None of them did everything well and anyone telling you otherwise is on an affiliate deal.

What I actually tested

I ran each tool on the same 12 meetings over three weeks. Mix of internal team calls, external client calls, and one genuinely chaotic all-hands where six people argued about roadmap priorities for 40 minutes. I scored each one on transcript accuracy, summary quality, action item extraction, search usability, and whether I would actually want to use it daily.

The transcript accuracy ranking surprised me. Otter won this category by a noticeable margin, especially on technical vocabulary. When our lead engineer said "we need to refactor the ingestion pipeline before we add another vector store" Otter got it right. Two of the other tools gave me "ingestion pipeline before we add another vector store" which, fine, but also one gave me "infection pipeline" which is a different kind of problem.

Where most of them fell apart

Action item extraction. Every single tool markets this feature. Every single tool struggles with it in real meetings where action items are implicit rather than explicit.

"Let's circle back on that next week" does not become an action item in any of these tools unless someone says "Sarah you are going to handle that by Friday." Real meeting language is messy and hedged and these tools are not smart enough yet to infer commitment from context.

Fathom got closest, probably because it integrates the AI summary tightly with the transcript rather than running them separately. But I still had to manually clean up about 30% of the action items it extracted.

The CRM integration situation

Fireflies wins here but with an asterisk. The Salesforce integration actually works and the meeting notes land in the right place automatically. The asterisk is that setup took me two hours and their documentation assumed I already knew which Salesforce objects I wanted to map to. If you have a dedicated RevOps person this is probably fine. If you are a small team doing your own setup, plan for a longer afternoon than you expected.

What I am actually using now

Fathom for client calls because the post-meeting experience is the cleanest and my clients occasionally ask me to share the notes which I can do directly from Fathom without exporting anything.

Otter for internal meetings because the transcript search is genuinely good and I have gone back to search "what did we decide about the pricing model" more times than I expected.

The honest recommendation

If you are an individual trying to stop taking manual notes during calls: start with Fathom, free plan covers most use cases.

If you are a sales team that needs CRM logging without manual data entry: Fireflies is worth the setup pain.

If accurate transcripts for documentation or compliance matter more than anything else: Otter.

If you are an enterprise IT team evaluating these for company-wide deployment and data handling requirements matter: none of these are self-hosted and you should probably be looking at a different category of solution entirely, but that is a different post.
