Introducing Quieta: Use AI Without Exposing Your Data

I have built Quieta with some friends because I realized how much data I was giving away to AI.

Like most people who use AI daily, we started small. A contract clause. A draft email. A financial summary. Then, over weeks, we noticed: we were feeding more and more of our professional lives into ChatGPT, Claude, Gemini, Mistral and other tools. Client names, project details, personal messages. Each one felt harmless. Add them up, and we'd handed a detailed map of our work to platforms we don't control.

The risk isn't one document. It's the accumulation. Over months, these platforms build a picture of your life, professional and personal. If that data is ever exposed (and breaches happen regularly), it's not one conversation that leaks. It's everything, all at once.

Lawyers, consultants, healthcare workers, HR teams all face this. But so do freelancers, students, anyone who uses AI intensively and doesn't want their entire history on someone else's servers. None of us had a good option. So we built one.

What Quieta does, and how

Quieta anonymizes your documents locally, on your device, before any data is sent to an AI chatbot. Names, dates, identifiers, project codes are replaced with neutral placeholders. By the time your text reaches the AI, the sensitive information is gone.

Under the hood, this isn't simple pattern matching. Quieta runs a bidirectional transformer model (about 1 GB) trained for Named Entity Recognition, directly on your machine. The model uses zero-shot recognition: it identifies sensitive entities from context, not from a fixed list. It doesn't need to have seen your client's name before. On NER benchmarks, it matches the performance of cloud LLMs, but your data never leaves your computer. No GPU, no internet, no server in the loop.

That's the combination that didn't exist before: real AI intelligence, your data stays 100% local.

The workflow

1. Load your document. Paste text, upload a file, or import from your clipboard. Quieta flags sensitive entities: names, emails, project codenames, internal references. You decide what to mask and what to keep.

2. Paste into your AI tool. Copy the anonymized version and use it in any AI chatbot. Get your analysis, your summary, your draft.

3. Get your original data back. Quieta restores the real names and identifiers in the AI's response. You read the final result with your actual data, not placeholders.

That's it. Your sensitive data never left your device.

Example: a contract clause

Before Quieta:

7.2 The total aggregate liability of Precision Manufacturing under
this Agreement shall not exceed the fees paid by Acme Corp during the
twelve (12) months preceding the claim. Contact for notices:
Sarah Chen (sarah.chen@acmecorp.com) and James Williams
(james.williams@precisionmfg.com).

After Quieta:

7.2 The total aggregate liability of [COMPANY_2] under this Agreement
shall not exceed the fees paid by [COMPANY_1] during the twelve (12)
months preceding the claim. Contact for notices:
[PERSON_1] ([EMAIL_1]) and [PERSON_2] ([EMAIL_2]).

You ask your AI tool "Is this liability cap standard for a services agreement?" and get useful analysis, without exposing who the parties are.

Who it's for

Anyone who uses AI regularly and has ever thought "I probably shouldn't paste this." Whether you're a freelancer, a student, or someone who doesn't want personal conversations on a server somewhere.

And especially professionals who handle confidential data daily: lawyers, healthcare workers, HR teams, consultants under NDA. For these roles, the stakes aren't just personal, they're legal.

Why not just use "private mode"?

Disabling chat history helps, but your data still travels to external servers and is stored at least temporarily. "Private" means the conversation won't train the model. It doesn't mean your data stays on your machine.

Quieta solves a different problem. The sensitive information is removed before anything is sent. The data simply isn't there anymore.
