About Changeflow
Changeflow watches web pages and tells you what changed. Not just "something changed" but what actually matters. Our AI reads the page, understands context, and summarizes the important bits.
Set up is simple. Describe what you want to track in plain English. Point it at a page with links and it turns into a feed of updates. We handle the tricky stuff like login walls and JavaScript, with a 99.9% success rate on pages other tools can't reach.
Business teams use Changeflow to track competitor pricing, monitor regulatory changes, follow news mentions, and keep tabs on market movements. Legal librarians at Am Law 200 firms monitor court dockets and legal citations. Compliance teams at Fortune 500 companies track FDA guidance and SEC filings.
Shared workspaces keep your team on the same page. API access lets you build monitoring into your workflows. Site Version Control gives you timestamped archives you can navigate through time.
