Redact your prompts on-device before AI ever sees them

Strip names, emails, secrets and client data out of your prompt on your own device, before any of it reaches ChatGPT or Claude. The model only ever sees placeholders. A made. product.
Hi. We are the small studio behind Airlock.
We kept pasting work into AI chats and then pausing: client names, emails, API keys, things that should never sit on someone else's server. The usual advice is "just be careful," which is not a real answer.
So we built Airlock. It detects the sensitive parts of your prompt and swaps them for stable placeholders ([NAME_1], [EMAIL_1]) right on your device, before anything reaches ChatGPT, Claude or Gemini. The model only ever sees the placeholders, and Airlock rehydrates its reply locally so it reads normally to you. The extension makes no network calls of its own, which you can verify in the network tab.
Free covers the regex rules and your own term list.
Pro adds an on-device model that catches names and companies, one-time, no subscription.
It is the sibling to Stash, our local-first memory for AI chats.
Airlock guards what you send; Stash keeps what you get back. Neither ever phones home.
Happy to answer anything.
