Harvey

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.

Why the subscription thing matters

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: claude for Claude Code, or an isolated codex app-server for Codex. Both return text with model tools disabled. Harvey handles the prospecting and mail operations itself.

Your selected subscription covers model calls, subject to its usage limits. That lets Harvey use its skills library for personalization and reply handling without a separate model API bill.
