MaskWise strips the personal data out of your documents on your own Mac, hands you a clean, token-efficient Markdown version to paste into any AI tool, and restores the real values when the answer comes back.

No connectors, no plugins, no browser extensions. You move the text yourself, by copy and paste. That is a feature: because your documents are masked on your Mac before anything is copied, the privacy promise is enforced by architecture, not by policy.
PDF, Word, Excel or pasted text. Parsed entirely on your machine, with structure preserved.
Every identifier becomes a reversible token, and the document becomes clean, lean Markdown built for AI input.
Copy unlocks only after you review. Claude, ChatGPT, Gemini, your internal chatbot, anything you can paste into.
Paste the answer into MaskWise. Tokens swap back to the real values locally, and anything uncertain is flagged, never guessed.
Masking is only half of what the conversion does. Raw copy-paste from a PDF or Word file drags along layout noise: repeated headers and footers, page numbers, broken line breaks, styling junk. MaskWise rebuilds the document as clean, structured Markdown, which is the most token-efficient way to hand a document to an AI.
Models read structure. A .md file with real headings, lists and tables gives the AI the shape of your document, so summaries, reviews and extractions come back sharper than from a wall of pasted text.
Lean input means longer documents fit in a single prompt, with space left over for your instructions and the model's answer.
If you pay per token, every round trip costs less. The cleanup that protects your data also trims the bill, on every single use.
Cloud redaction tools ask you to trust a privacy policy. MaskWise runs detection and masking entirely on your Mac. The only thing that ever leaves is the masked text you reviewed and copied yourself.
Everything MaskWise learns, your vocabulary, corrections and the token vault, is encrypted on this Mac and used only to improve detection. Clear the vault and the link between tokens and real values is gone for good.
No detector catches everything, and you should distrust any tool that claims it does. MaskWise pairs pattern rules with an on-device recognition model, with an optional Apple Intelligence deep scan, then puts you in front of a review screen before a single character leaves. That review step, not blind trust, is the safety mechanism.
If your documents are full of other people's personal data, and your industry has rules with teeth, MaskWise was built for your desk.
Notes, referrals and records are dense with patient identifiers, and the pull to use AI is strongest here. Built first for clinical work.
Contracts, filings and discovery carry privileged client data that confidentiality will not let you paste into a chatbot.
Statements, returns and client files mix personal identifiers with account data you cannot paste into a chatbot.
