AI that checks whether Reddit claims are actually backed by their sources
A Validate Claim button appears on Old Reddit comments that contain links, so verification is one click away instead of a separate research session.
Instruction fine-tuned models break a comment down into the discrete factual claims the author is implicitly or explicitly asserting.
The tool fetches the linked source and evaluates each claim against it, showing where the citation does and does not hold up.
The codebase is public and the roadmap is shared, covering multi-source comments, Reddit posts, Twitter, and Wikipedia support.

Scans thousands of websites to see whether a statement is backed by other sources.
Delivered as a Chrome extension so checks sit alongside the content you are reading.
