Ownhand writes in your own voice. Claude passes a rough draft, or what you want to say, and Ownhand returns text that seems like you wrote it, fitted to where it is going.

What it does:

• Builds your Hand, a voice profile, from 5 to 10 things you wrote yourself: Slack messages, emails, PR descriptions.
• Fits each draft to one of 12 occasions: Slack DM, channel post, internal email, formal email, cold email, warm email, cold or warm proposal, PR description, code review comment, docs, and status update.
• Matches the thread when replying. Claude passes the last messages verbatim, and the reply answers what was actually said.
• Learns from what you send. After you send a draft, Claude reports the exact text that went out. Ownhand compares it with the draft and turns your edits into rules for next time. A reason you give, like "too formal", becomes a rule right away.

Ownhand never sends anything. It returns a draft for you to read, change and send yourself.

Tools: write (draft in your voice), send_feedback (report what you sent), get_hand (see what it has learned), create_hand and update_hand (add samples, pin or reject a rule), and get_account (credit and usage).
