Use Reach-book.com in ChatGPT

Find business contacts from inside ChatGPT, using your workspace's credits.

Connect

In ChatGPT, add the Reach-book.com app and sign in.
Pick the workspace to connect.
Optionally tick Also allow saving found contacts as prospects when I ask.

Your account name and the workspace name are shared with ChatGPT. The connection can't send email or read your inbox.

What you can ask

Find a business contact at a company (use a company domain, not a personal email service)
Read the results of a lookup
Save a found contact as a prospect (if you allowed it)
Show which workspace is connected

Approving lookups

Every lookup that costs credits needs your approval in the browser: Approve lookup · N credits. A named-person lookup uses 1 email lookup credit; a decision-maker lookup uses 2. Approval requests expire after 30 minutes.

Manage or disconnect the app any time from your user menu → ChatGPT connections.
