What Hebno reads

A Fathom recorded call attached to a chat.
Hebno reads only
Hebno does not write to Fathom. It does not record or join calls, edit summaries, complete action items, create clips or change sharing. To schedule a follow-up, use Google Calendar or Outlook Calendar.Link a project to a client domain
Each Fathom call lists the email domains of its calendar invitees. Linking a domain marks which calls belong to an engagement, so you can ask “what did we agree last week?” without naming the call.- Open the project and select Brain.
- Under Linked records, select Link record, then Fathom.
- Enter the client’s email domain, for example
contoso.com, and select Link.
Use Fathom in chat
-
Attach: open the + menu, choose Sources → Fathom, pick a call, then pick the summary, action items, transcript or full record. Or type
/and choose Fathom. -
Ask: name the client, domain, person or date. For example:

What did Sarah Chen say about the readout date on the 28 October call? Quote the transcript.
Draft a recap email for Contoso from today’s Fathom summary.
- Research runs show a Reviewing Fathom step, with a chip for each call and the source used.
- Agents can read Fathom on a schedule, for example a Monday digest of last week’s client calls with open action items. Fathom has no write actions, so agents only read.
