Purpose-built for PDF monitoring
Watch any public PDF
Legal docs, T&C, price lists, product datasheets, government publications, financial reports — any publicly-linked PDF.
Cryptographic change detection
Every fetch hashes the PDF bytes. If the hash changes, a new version was published — even if the filename stayed the same.
Extract and diff text
PDFs are parsed to extract text content, so you see exactly which paragraphs, prices or clauses changed — not just 'PDF changed'.
Instant version alerts
Slack, Discord, Teams, Telegram, email or webhook the moment a new version is detected. Includes a preview of what changed.
Section-level diffs
Structural comparison highlights added, removed and edited sections. Perfect for tracking policy or T&C changes.
Version archive
Every version of the PDF is stored so you can reference exactly what the document said on any given date — critical for legal and compliance workflows.
Evidence trail included
SHA-256-chained evidence bundles export as ZIP with all captured versions and a signed manifest. Perfect for compliance audits.
6-hourly (hourly on Pro)
PDF checks run every 6 hours by default and hourly on Pro. Custom intervals on Agency.
