Document analysis that leaves no trace

Your document is read, never kept.

Word and text files are opened on your own machine and never sent. PDFs and images do go out for analysis — but you see exactly what goes, before it goes. None of it is stored.

Your device
The network You see what crosses this line, every time.

The mechanism

Where the line sits

Most tools ask you to hand over the file first and explain themselves later. This one is built the other way round.

The file opens locally

Your browser draws the preview. A PDF's first page is rendered on your own screen, a Word file is unwrapped here, an image is resized here. Nothing reaches the network in this step.

You see what will go

From Word and text files, only the extracted text travels — the file stays with you. For PDFs and images the file itself travels, because that is the only way to read a page's layout or a photograph properly. The screen tells you which it is.

It goes, returns, and is gone

Whatever is sent passes through our own server to the analysis model and straight back to you. It is never written to disk along the way: no database, no file store, no logs.

What this site does not do

The principles we hold to, in order to serve you as well as we can.

It does not hide what is sent

Extracted text or the file itself — whichever is going, it is named on screen before you press the button. No surprises.

It does not send Word or text files

For those types the parsing finishes in your browser. Open the network tab and watch: the file bytes are never in a request.

It does not store anything

No database, no file store, no accounts. Whatever is sent passes through a stateless function and is gone once the answer is returned.

It does not track you

No analytics, no advertising pixels, no third-party cookies. Your browser holds only your language choice and an anonymous number for the weekly query count — that number is deleted and replaced every week, and is never sent to the server.
