FAQ

Questions.

Is it really free?
Yes. The core detection and blur work entirely locally, forever free. The Pro plan unlocks advanced features like Heatmap, PDF Scanner, and unlimited cloud verification.
Does it send my data anywhere?
90%+ of analysis runs in your browser. Only gray-zone content (score 40-74) is sent to our backend for verification. No text is stored. Ever.
Which languages does it support?
All of them. OriginAl analyzes mathematical structure, not words. It works in Italian, English, German, Spanish, Arabic, Chinese — any Unicode language.
Does it slow down my browser?
No. CPU usage during scroll is under 10%. We use chunk processing and debouncing to keep the browser completely fluid.
Who is it for?
Knowledge workers, journalists, recruiters, students, and anyone who wants to consume authentic information. Also teams and companies with the Business plan.
