AFileFix Document Comparison review
A free web tool for plain-English PDF and DOCX comparisons, not visual redlines.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
AFileFix Document Comparison is a free web tool for reviewing two versions of text-heavy documents. It supports PDF, DOCX, and mixed-format pairs, making it suitable for contracts, policies, proposals, reports, and similar files. The product identifies added, removed, and modified content, then organizes the results into a structured report with before-and-after text. Its plain-English explanations are designed for readers who need to understand what changed without manually scanning both documents.
The comparison workflow focuses on content clarity rather than visual document editing. AFileFix highlights changed terms, numbers, and dates, and provides section-by-section breakdowns to help users review important revisions. It can also generate a downloadable DOCX report. The published product details specify support for documents up to 25 MB per file, and the tool requires selectable text. These capabilities make it a practical fit for text-led review where the main question is what wording changed and how that change can be understood.
AFileFix is available on the web and uses the Anthropic Claude API for its AI features. Its narrow focus is useful for buyers who want a free, plain-English comparison of PDF and DOCX versions without a paid plan. It is less suitable for legal or production workflows that require formatting diffs, layout-change detection, or formal redline output. Choose it for accessible change summaries and DOCX reporting; choose another document comparison product when visual fidelity or legal markup is central to the review process.
