Seriesly vs Fathom

The difference

Fathom nails the single meeting — fast, accurate summaries, easy clip-sharing, CRM sync, and Ask Fathom over your call history on paid plans. What it does not do is treat a recurring meeting as one continuous thread; each call lands as its own record, and cross-meeting context is something you go ask for.

Seriesly carries a recurring meeting’s unresolved threads into the next occurrence automatically. It ages open loops across your whole portfolio with an owner lens (Mine / Owed to me / By person), writes a delta of what changed while you were away, drafts an auto pre-meeting brief, and runs research across your meetings, calendar, and Obsidian vault — not just past calls.

Fathom is a cloud account, though it does not train on your content. Seriesly goes further on privacy: notes live in a local SQLite file on your Mac, transcription runs on-device, it works offline, and nothing trains a model by default.

Where Fathom is strong

• ✓A genuinely generous free plan with unlimited recording
• ✓Fast, clean summaries and easy highlight-and-share clips
• ✓Ask Fathom across your meetings, CRM sync, and a bot-free desktop mode alongside its bot

Where Seriesly goes further

• →Series memory is automatic. Open threads from a recurring meeting surface next time with no query — Fathom keeps each call as its own record.
• →Delta. A written diff of what changed across every thread while you were away — Fathom has no equivalent.
• →Auto pre-meeting prep. A brief synthesized from past meetings and your tools, ~20 minutes before the call.
• →Owner-lens open loops. Aged action items across the whole portfolio, sorted by who owes whom — not a per-meeting list.
• →Cross-source research over your own sources. Your meetings, calendar, and Obsidian vault, with citations — not just past calls.
• →Local and offline by default. On-device transcription, notes on your Mac, no cloud account required.
