Copy as usual. The Quieta app replaces your sensitive data with pseudonyms before you paste into ChatGPT or Claude, then restores them in the answer.
Type as usual. The Chrome extension masks your sensitive data in most web AIs, and restores them in the reply, right on the page.
Mirror gives AI agents a masked copy of your folders. What it writes appears in your folder, with your real data restored.
One local-first engine. Your data never leaves your machine in the clear, whatever the channel.
That's exactly why privacy matters more than ever. What you hand to an AI can train a model, on someone else's servers, with no way back. Quieta masks your sensitive data locally, before it ever leaves your machine.
Privilege survives the data room.
Due diligence, briefs, case files: the AI only ever sees pseudonyms, never the real identity of the parties.
Candidate files, without the identities.
Resumes, assessments, interview notes: the AI helps you sort and write while names and contact details stay masked.
Preserve patient anonymity.
Reports and clinical cases worked through with AI; names, dates and identifiers stay masked on your machine.
NDAs hold across every deliverable.
Confidential client data, slides, analyses: you produce with AI without a single client name reaching it.
Most privacy tools process your data on their servers: to "protect" it, they first receive it. With the Quieta app, detection, masking and restoration all happen on your machine. Nothing to send, nothing to expose.
Unplug your Wi-Fi. Quieta still works.
Fully offline by design.

Mirror keeps two folders in sync. Yours holds your real files. The agent's holds masked copies, and that's all it ever sees. What it creates appears in your folder, with your real values restored.
Word · Excel · PowerPoint · PDF · code — in real time, entirely on your machine
The agent never meets a single real name.
You never touch a pseudonym.
Wherever you work with AI, Quieta is with you.
