How it compares
Serial Notes vs Granola, Otter, and Fathom
They're all good tools — but they're cloud subscriptions. Serial Notes is a free, open-source Mac app that records, transcribes, and summarizes meetings entirely on your machine, then saves a plain Markdown file you own outright.

* Free tiers are capped — Granola 25 meetings total, Otter 300 minutes/month, Fathom 5 AI summaries/month. Granola records locally but enhances notes with cloud AI, so it needs a connection. Otter and Fathom now offer bot-free capture modes but default to a bot that joins the call. Details verified June 2026; see each product’s pricing page.
Serial Notes vs Granola
Granola is the closest tool in spirit: a polished Mac app that records from your computer's audio without sending a bot into the call. The difference is what happens next. Granola enhances its notes with cloud AI, so your transcript leaves your machine and the app needs a connection and an account. Its free tier covers 25 meetings total, then it's a subscription.
Serial Notes keeps the entire pipeline — recording, transcription, speaker labels, summaries — on your Mac. It works offline, needs no account, and every meeting lands as a plain .md file in a folder you choose, readable in any editor. It's also open source, so you can verify all of that rather than take our word for it.
If you want AI-polished prose notes and don't mind the cloud, Granola is a fine choice. If you want your meetings to stay on your machine — and your notes to outlive any app — that's what Serial Notes is built for.
Serial Notes vs Otter.ai
Otter is the veteran of cloud transcription, with mobile apps, real-time collaboration, and team workspaces. It's built around its cloud: audio is transcribed on Otter's servers, an "Otter Assistant" bot joins your calls by default, and the free tier caps you at 300 transcription minutes per month.
Serial Notes takes the opposite approach. Nothing joins your call and nothing is uploaded — your Mac does the transcription itself, with automatic speaker labels, for unlimited meetings at no cost. Notes are local Markdown files instead of documents living in someone else's web app.
If you need shared team transcripts on every platform, Otter has features Serial Notes doesn't. If your meetings happen on a Mac and you'd rather they stay there, Serial Notes does the job without the bot, the account, or the meter.
Serial Notes vs Fathom
Fathom is aimed squarely at sales and customer teams: a bot joins the call, recordings live in Fathom's cloud, and highlights sync into your CRM. Recording is free without limits, but AI summaries are capped at five per month before the subscription kicks in.
Serial Notes has no bot, no cloud, and no cap — summaries and action items are generated on-device by Apple Intelligence for every meeting. There's no CRM integration, by design: you get a clean Markdown file that flows into whatever system you already use, from Notion to Obsidian to plain folders.
If your workflow is pipeline reviews and call libraries shared across a revenue team, Fathom fits that shape. If you want private, permanent notes from every meeting you attend, Serial Notes is the simpler, freer answer.
