Mask
Hide private details before your text reaches any AI
Mask reads your text in the browser and swaps private details for placeholders before anything leaves your machine. It catches names, companies, emails, phone numbers, account numbers and addresses, plus your own saved term lists for client names and codenames. The original text stays on your machine. If you want the AI to help with the text, the optional Ask-the-AI relay sends only the masked version and swaps the real details back into the reply. Mask is $9 a month, unlimited text length.
Features
Catches names, companies, emails, phone numbers, account numbers and addresses. Custom term lists for client names and codenames. One click to copy or insert into ChatGPT or Claude. Optional Ask-the-AI relay sends only the masked text. Unmask swaps the real details back into the reply. Tested: 26 of 26 seeded values (100%) caught across 12 synthetic business texts.
Use Cases
Support agents summarising long complaint threads. Founders pasting investor or client emails into ChatGPT. Teams writing proposals, quotes and follow-ups with AI help. Anyone whose work text contains customer details they do not want on an AI provider server.
Comments
Work text is full of client names, account numbers and addresses, and it gets pasted into AI tools every day. Mask swaps those details for placeholders in your browser before anything leaves your machine, and puts the real values back into the reply. The mapping never leaves your device. Masking lowers exposure - it is not anonymisation. Tested on 12 synthetic business texts: 26 of 26 seeded values (100%) caught. Happy to answer questions.
