Fathom vs Sembly AI

Fathom and Sembly AI are both meeting assistants tracked by AIDiveForge. Below is a side-by-side comparison of pricing, capabilities, platforms, and ownership — sourced from each tool's live website and verified before publishing.

Fathom

Fathom sits in the crowded meeting-intelligence space alongside Gong and Otter, but positions itself as a passive capture tool rather than a coaching platform. It records video calls across Zoom, Teams, and Google Meet, then generates summaries and action items automatically—users report reclaiming roughly 38 minutes per meeting. The free tier is genuinely unlimited for one user; paid plans scale to enterprise teams with shared visibility. The main friction: exact pricing isn't listed on the homepage, forcing a sales conversation to know costs. Language support and international availability remain unclear from public-facing materials, a notable gap for global teams.

Sembly AI

Sembly sits inside Zoom, Teams, and Webex calls and produces structured output from every conversation: summaries, minutes, assigned action items, risk flags, and client-ready documents like proposals and briefs. The multi-meeting search lets a team lead pull a topic thread across weeks of calls in seconds rather than scrubbing recordings. The accountability layer extracts task owners and deadlines from discussion, then syncs to Salesforce, HubSpot, Notion, and 50+ other tools. Where it strains: teams that need custom workflow branching or want to self-host the model run out of room fast — no API, no self-hosted option, no open architecture.

Pros	Automatically generates summaries and action items, saving average 38 minutes per meeting Searchable transcripts and ability to query past conversations with Ask Fathom feature Works across team sizes from 1 to 1000 with shared visibility and consistent execution SOC 2 Type II, GDPR, HIPAA compliant with SSO/SCIM support Eliminates manual follow-ups and administrative overhead	Generates client-ready documents — proposals, briefs, pitch decks — directly from meeting content, so a consultant leaves a discovery call with a draft deliverable instead of raw notes. Cross-meeting search by keyword, speaker, or topic across the full archive, which means a project lead can surface every commitment or risk flag from a six-month engagement without scrubbing recordings one by one. Action item extraction assigns owners, deadlines, and dependencies automatically, so the post-meeting 'who said they'd do what' conversation stops happening. HIPAA compliance is supported, which opens the tool to healthcare-adjacent professional services teams that most meeting intelligence tools cannot touch. Syncs to Salesforce, HubSpot, Notion, Slack, and 50+ tools, so meeting output lands in the system of record the team already uses rather than sitting in a separate dashboard nobody checks.
Cons	Specific pricing details not shown on homepage No mention of supported languages or international availability	No public API is available, so any team that needs to pipe meeting data into a custom internal system — a proprietary CRM, a data warehouse, an internal analytics layer — cannot do it directly and must work through whatever integrations the vendor supports or accept a dead end. No self-hosted option exists, which means teams with hard infrastructure requirements — on-premise data mandates, jurisdictions outside US/EU residency, or internal security policies that prohibit third-party cloud processing of conversation data — cannot use this tool and move instead to self-hostable transcription and summarization pipelines they control. The agentic document generation is described at the category level but the depth of custom template control is bounded by what the vendor's template library supports — teams with highly specialized deliverable formats report needing to post-edit outputs significantly before they are client-ready.

Bottom line

Only Fathom exposes a public API. Choose based on which difference matters most for your workflow.
