Live demo

Analyze a document with the same API you'll use in production. We don't keep the file and each visitor gets 5 analyses a day.

2What you expect

With “Detect automatically” we tell you what the document is and extract its data. Pick a type to get a verdict.

We do not keep the document: it is deleted as soon as the analysis ends (storage "none").

5 analyses a day per visitor, protected by an ALTCHA proof of work, with no third-party cookies.

What happens when you click Analyze

  1. 1

    Your browser solves an ALTCHA proof of work: no third-party captchas and no cookies.

  2. 2

    The document travels encrypted over TLS to our API, with storage "none".

  3. 3

    OCR, classification and deterministic validators return the verdict with reasons.

  4. 4

    The file is deleted at the end. Only an anonymous counter remains for the daily limit.

And for the record…
