Ask your PDF—and verify the answer.

Upload a searchable PDF or use the built-in evaluation report. The local evidence engine uses Unicode-aware lexical retrieval to find relevant passages, produces safe deterministic answers when possible, traces answer claims to exact page text, checks conflicting numeric context and false premises, and treats “not found” as a valid result instead of inventing an answer.

Standalone upload uses PDF.js when available. Production self-hosts the parser and adds OCR fallback for scanned documents.
