What is Changeflow?

Changeflow is an enterprise web intelligence platform. It monitors web pages, PDFs, RSS feeds, and APIs for changes, then uses AI to tell you what changed, why it matters, and what to do about it. Used by compliance teams, legal researchers, competitive intelligence analysts, and procurement teams at Fortune 500 companies and Am Law 200 firms.
