About

Harvey finds businesses to sell to, writes cold email that references something specific about each one, sends it, reads replies and works conversations toward a meeting. It runs on the user's machine in a loop and calls the Claude Code or Codex CLI, so model use is covered by the user's existing subscription instead of a per-token API key. Drafted emails wait in an outbox for approval, and a local dashboard shows the pipeline.

Use cases: sales-outreach, lead-research, sales-prospecting, email
