Semantic Web Diff

Semantic change detection for webpages and text. Compare two versions, ignore cosmetic noise, and return a structured JSON report of meaningful changes such as pricing, availability, deadlines, requirements, policies, specifications, and status.

Provide two public static HTTPS URLs or HTML documents. Get price, date, availability, terms, link, and call-to-action changes with source evidence. Run the prefilled example.

Compare CSV and JSON snapshots to find added, removed, and changed records. Keep real price changes while ignoring equivalent number formats. Receive JSON and CSV reports. Up to 5,000 rows per side.
