Paste. Protect. Copy. Use any AI.
Free, no account. Up to 500 characters here; the real engine finds more and takes whole files. How it works with files.
upii swaps names, addresses, account numbers and other personal data for tokens. You send the protected text to any AI, paste the answer back, and the real names return. Files too: PDF, Word, Excel, scans.
14 days, 40 pages, no card. Sign in with an e-mail code. No password.
The same person keeps the same token through the whole project, so the AI can still follow who is who.
It replaces the personal data it detects. Some items can be missed, which is why you review the result before you use it.
Context can still identify someone. A file about “the only bakery in Wevelgem” says a lot even with the name removed. You stay responsible for what you share.
Pictures inside PDF and Word files are removed, not blurred. A name inside a picture cannot be tokenised reliably.
PDF, Word, Excel, CSV or text. Scanned pages and photos are read first. Files are grouped by project.
Every replacement is shown next to the text. Keep a word, protect another, re-run the file. Nothing leaves until you say so.
Download the protected copy or copy the text into any AI. Paste the answer back and the real names, numbers and dates return.
If the PDF has a text layer, you get a PDF back: the personal data is replaced by tokens and the pictures are removed. A Word file stays a Word file.
Excel, CSV, text files, scans and photos come back as a Word document with the protected text only. A PDF with a scanned page comes back as Word too.
One click gives you a zip of every finished file in a project.
Tell upii which words to always hide and which to never hide, for your whole account or for one project. It matches the exact text you type, not patterns.
Each project keeps a log of what was protected, re-run, shown or restored, and by whom. Export it as PDF. No client names or original values are written in it.
Developers can call upii with a key from the dashboard. With the stable style, the same value always gets the same token.
No slogans. This is what happens to a file.
Files are processed and stored in EU data centres.
The real names are kept in an encrypted list. Each project has its own key, derived from a master key and the project. The protected copy holds tokens instead.
Each time a real name is shown or an AI answer is restored in a project, the project's activity log records who and when, and the reason if you give one. Export it as PDF. Restoring in the quick box on this page happens in your browser and is not logged.
Archive a project, then delete it for good: files, protected copies and the encrypted list of real names are erased.
You sign in with a code sent to your e-mail. There is no password to leak, reuse or forget.
Text sent through the quick box is handled in memory and not stored after the answer. Files in a project are deleted automatically after a fixed period, or earlier when you delete the project. The privacy page has the periods.
Let AI summarise a ledger, draft a letter to the tax office or explain a bank statement, without a client's name, number or account leaving your project.
Ask an AI to structure a case file, compare two contracts or draft a first reply, with parties, witnesses and addresses replaced consistently.
Every plan has every feature. The only difference is how many pages you can protect each month. Prices exclude VAT.
A scanned page or a photo counts as 3 pages, because it is read first. Cancelling takes effect at the end of the period you paid for. Payments are handled by Mollie: card, iDEAL, Bancontact. Invoices are sent by e-mail, with VAT where it applies.
Any. ChatGPT, Claude, Copilot, Mistral, or the model your firm runs itself. upii never talks to the AI for you; you stay in control of what you send.
Yes. A token such as {{PERSON:fedcbafedc}} keeps its place in the sentence and stays the same for that person across the whole project, so the AI can reason about “the buyer” and “the seller” as usual.
Paste the AI's answer into the project's Restore box. upii swaps every token back to the original value, using the encrypted map of that project only. The restored text is shown to you and not stored.
Yes, the same engine, limited to 500 characters, with no files and no saved projects. Start the free trial to protect whole files, scans included.
One page of a PDF or Word file is one page. A scanned page or a photo counts as 3 pages, because it must be read first. Spreadsheets and text files count by their size.
upii is a child company of chut.app, built by BV CHUT.APP in Wevelgem, Belgium. We built it because our own accountant could not use AI on client files. If something is wrong, you write to a person: support@chut.app.
