AFileFix Document Comparison

Purpose: The tool compares two document versions and identifies added, removed, and modified content.
Supported files: It accepts PDF or DOCX files, including mixed-format pairs, up to 25 MB per file.
Report: Results appear on screen, and a downloadable DOCX report includes the analysis.
Change explanations: Each change includes a plain-English explanation that describes what changed and why it might matter.
AI processing: The comparison sends both files to Anthropic's Claude API, and AFileFix says it deletes them from its server within minutes after processing.
AI data retention: The page says Anthropic retains API data for up to 30 days for safety review, then permanently deletes it, and does not use it to train AI models.
Best suited to: The page recommends structured, text-heavy documents such as contracts, policies, proposals, terms of service, and manuals.
File limits: Scanned PDFs and password-protected PDFs are not supported, and the tool does not OCR scanned files.
Long documents: Documents over approximately 150 pages may be truncated, with content beyond the analyzed portion left out of the comparison.
Visual changes: The comparison focuses on text content and does not detect layout-only changes such as font, spacing, page breaks, or margins.
Comparison scope: Each run compares one pair of documents; it does not provide automatic three-way comparison, Word track changes, or legal redline output.
