From the README
An autonomous sales agent that runs on your Claude Code or Codex subscription.
Harvey finds businesses worth selling to, learns something specific about each one, writes cold email that references it, sends it, reads the replies, and works the conversation toward a meeting. It runs on your machine, in a loop, on its own.
The unusual part: there is no model API bill. Harvey uses your Claude Pro or Max subscription through Claude Code, or your ChatGPT subscription through Codex. Model calls use the plan you already pay for, without an API key or per-token API billing. Claude is the default; Codex is an opt-in provider on macOS and Linux.
Every other autonomous sales agent bills you per token. That is the whole reason they cost what they cost: an agent that thinks in a loop, all day, is an agent that burns API credits in a loop, all day. Vendors solve this by thinking less — shorter prompts, cheaper models, fewer passes.
Harvey uses the subscription-backed CLI for the provider you choose:
