Compare PDF revisions by changed page

Compare extractable text in two PDF revisions and inspect changed pages without an LLM call.

1. Upload both revisions separately and retain both capabilities.
2. Call compare_pdfs with left_document_id, left_capability, right_document_id and right_capability.
3. Use returned changed pages to select read_document or bounded page rendering.
4. Review relevant changes before drawing a business or legal conclusion.

Comparison uses page-aligned normalized native text. Page insertions can shift subsequent matches. Text-identical PDFs can have different layouts, signatures or images; this tool does not establish legal equivalence.

Start with the included tools

Indexing a PDF uses the published x402 document price. Retrieval and verification are included with the returned short-lived bearer capability; no paid generation is required for these workflows.
