What it is

AFileFix Document Comparison is a free web tool for comparing one pair of document versions. It identifies added, removed, and modified text in PDF or DOCX files, including mixed-format pairs, with a 25 MB limit per file. Results appear on screen, and a downloadable DOCX report provides analysis and plain-English explanations of each change and why it might matter. The tool is recommended for structured, text-heavy documents such as contracts, policies, proposals, terms of service, and manuals.

Both files are sent to Anthropic's Claude API for processing. AFileFix says it removes uploaded files from its server within minutes. Anthropic retains API data for up to 30 days for safety review, then deletes it, and does not use it to train AI models. The comparison covers text, not layout-only changes such as fonts, spacing, page breaks, or margins. Scanned and password-protected PDFs are unsupported, and the tool does not OCR scanned files. Documents over approximately 150 pages may be truncated. It does not provide three-way comparison, Word track changes, or legal redline output.
