Diff the Law
Source-groundedWatch USCIS, State Department, FAM, Federal Register, and court pages. Each snapshot is hashed and timestamped. Heading NLP extracts eligibility, skip, and evidence rules. Form catalogs stay frozen until a person reviews.

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. Form catalogs are never auto-updated from a crawl. Always verify against the official source.
