Fathom

Fathom is an AI meeting assistant that automatically records, transcribes, and summarizes your video calls. It works across platforms like Zoom, Google Meet, and Microsoft Teams, generating highlights and action items so your team can stay focused during meetings and catch up quickly afterward.

With the Sim Fathom integration, you can:

List and filter meetings: Retrieve recent meetings recorded by you or shared with your team, with optional filters by date range, recorder, or team.
Get meeting summaries: Pull structured, markdown-formatted summaries for any recorded meeting to quickly review key discussion points.
Access full transcripts: Retrieve complete transcripts with speaker attribution and timestamps for detailed review or downstream processing.
Manage teams and members: List teams in your Fathom organization and view team member details to coordinate meeting workflows.

How it works in Sim: Add a Fathom block to your workflow and select an operation. Provide your Fathom API key and any required parameters (such as a recording ID for summaries and transcripts). The block calls the Fathom API and returns structured data you can pass to downstream blocks — for example, sending a summary to Slack or extracting action items with an AI agent.
