Compare text-based PDF, TXT and Markdown versions for free. Review added and removed passages with page references, then export a document change list.
Create an old TXT saying “Delivery: Friday” and a new one saying “Delivery: Monday”. Comparison should list the old text as removed and the new text as added, with TXT page reference 1.
One file per side, up to 30 MB, and up to 200 pages per PDF. Combined text is limited to 20 million characters; excessive differences or timeouts require smaller sections. It does not recognize scans or compare layout, seals or images. PDF text extraction order can affect results.
Their text-layer order, segmentation and whitespace can differ. Try ignoring repeated whitespace and check the originals.
No. It lists text changes. Their business or legal significance requires contextual review by the appropriate professional.

Scanned PDFs need OCR first. Text comparison does not guarantee that page layouts or visual changes match.
Read KitNelo data and privacy detailsSelect two text-based PDFs to inspect added and removed passages with available page references. Run OCR first for scanned files, and review important pages visually because a text comparison cannot guarantee that layout or image changes have been detected.
Provide two TXT, Markdown or supported PDF versions and inspect the differing text in context. Check reordered passages and extracted line breaks before interpreting a change, since document text extraction can separate words differently from their visual page layout.
Review the identified additions and removals, then export a change list for follow-up. Keep the two source versions with the report so a reviewer can verify page references and inspect visual differences that fall outside text comparison.
