Technically, Quieta pseudonymizes: each real value maps to a pseudonym, and the mapping stays on your machine. That is what keeps it reversible for you and useless to anyone else.

Pseudonyms in the answer flip back to your real values, locally. You read the result as if nothing had ever been masked.

No account to create. We only ask for your email to send your license key, free plan included.

An on-device AI spots sensitive data by context, on your machine. It recognizes names, clients, addresses, identifiers and more, even ones it has never seen before, with no predefined list.

Names, emails, phone numbers, addresses, client names, internal references and other identifiers.

Yes. You can force certain terms to always be masked (a blocklist), like a client name or a codename, and exclude others so they stay untouched (an allowlist), like your own company. The lists stay on your machine.

Your clipboard (any app where you can paste text), AI in your browser via the Chrome extension, and your AI agents via Mirror. One local-first engine, several ways in.

Because it ships with a complete AI model that runs locally on your machine to detect and mask your sensitive data. That model is stored on your disk and never sent anywhere, and it is what makes the whole thing work with no cloud dependency. The trade-off is size: one download, no ongoing data transfer after that.

Yes, on macOS and Windows. Quieta is a desktop app; there is no mobile version. The browser extension covers the AI you use in Chrome.

Yes. Quieta is a signed build for macOS and Windows, it runs entirely on your machine, and it never phones home. The one-time download of about 1 GB is the local AI model; after that, nothing is sent anywhere.

No. You copy, Quieta masks on the way, you paste; restoring the real values in the answer is just as instant, locally.

Claude Cowork, Mistral Work, Codex for Work, and any AI agent that reads a local folder on your machine.

No. The agent only ever sees the masked folder; the table linking pseudonyms to real values never leaves your machine. It never has the key.

They come back to you with your real values restored, automatically, locally. You get complete, usable files, never pseudonyms.

Word, Excel, PowerPoint, PDF and code, synced in real time in both directions.

By default, no: they run with your account's rights and see your whole disk. Config-level scoping (AGENTS.md, profiles) constrains the tools but isn't airtight; only a sandbox (container, VM) truly confines them. Quieta takes another angle: Mirror has the agent work on masked copies, so what it reads and sends never carries your real values. Ideally, combine both.

A gateway masks server-side: your raw data still passes through a third party. Mirror masks on your machine, before anything is sent. Nothing passes through.

Yes. Mirror covers your agents and folders, the extension covers AI in your browser. Both run locally, at the same time.

Pro. Mirror keeps a masked folder in sync for your AI agents, and you get their deliverables back with your real values restored. Word, Excel, PowerPoint, PDF and code.

Masking pauses until the next month, or you can upgrade to Plus for unlimited use.

Plus is for individuals who process documents daily. Pro adds Mirror (masked folders for AI agents) plus team features: batch processing, custom regex, audit reports and admin dashboard.

Yes. No lock-in, no hidden fees. You keep access until the end of your billing period.

You pay for 10 months and get 12, that's 2 months free.

All major credit cards via Paddle. Invoices are available for Pro plans.
