Diff the Law

Source-grounded

Track official legal and government pages over time. When the text changes, you get a PR-style diff — not an AI guess.

AI period compare (Reg Diff)

Related: Document Studio → Regulatory Change Diff uses AI for historical periods; this tool diffs real page text.

Track an official page

Paste a government or regulator URL. We store a baseline snapshot, then surface a unified diff when the page changes.

Watchlist / smart alerts

When a tracked page changes, LegalLens publishes a feed item and matches your enabled Smart Alerts (query vs page title, agency, jurisdiction, and sample diff lines). Matching alerts can email you if Resend is configured. Manage alerts on the dashboard watchlist panel.

Not legal advice. Diffs compare extracted page text only; layout/JS-only changes may not appear. Always verify against the official source.
