SDR Messaging Engine

Build an AI twin of a buyer persona, then write or paste your own cold email and run it by the twin. They roast it from their point of view and you refine together until the twin says yes, they would reply. When the twin says yes, the message is ready to send. Bring your own Anthropic API key.

1 · Build a buyer twin

Pick the role you are selling to. Paste real call notes or emails to sharpen the twin, or build it from the role alone.

Persona / role

Voice of customer — paste call notes / transcripts & emails (optional)

The twin and every round of feedback run on your own Anthropic API key (add it in Settings) — billed to your account, never anyone else's. New here? first — no key needed.
