FAQ

Common questions

Does it work on PDFs opened in Chrome?
Yes — Deadline Detective works on PDF files rendered in Chrome's built-in viewer, as well as any standard web page. It reads the visible text layer of the document.
Does it send my documents to any server?
No. All text processing happens locally in your browser using JavaScript regex patterns. No text is transmitted anywhere. There is no server, no account, and no data collection.
How accurate is the deadline detection?
Deadline Detective uses a comprehensive set of legal and business date patterns — absolute dates, relative deadlines, notice periods, and expiration language. It flags potential misses rather than guaranteeing legal accuracy. Always verify critical deadlines independently.
Is it really free? What's the catch?
It's genuinely free. No freemium limits, no paid tier. It's a utility tool built by AIBridges to demonstrate what focused, local-first browser tools can do for legal professionals.
