AI should read your code,
not your secrets.

LocalMask scans your repo, masks every secret, organizational data, and PII into safe tokens, and lets you share code with AI — without leaking passwords, internal hostnames, or company details.

Local-first privacy for AI coding

AI should read your code,
not your secrets.

LocalMask runs entirely on your machine. It scans your repo, masks every credential, key, piece of PII, and organizational data into reversible tokens, then sends only safe tokens to Claude, GPT, or Gemini. Answers come back and get rehydrated locally — you stay in full control, and the real secrets never leave your local environment.

No spam — one note when the private beta opens.

You're on the list. We'll reach out when the beta opens.
