Performance Test of Document Markup Tools

Welcome to the first comprehensive performance test of legal document comparison tools!

Legal document authors often move existing text while editing. Failure to detect such changes leads to cluttered, unreadable redlines.

Therefore, we assess each comparison tool's ability to detect edited and moved content. Each test evaluates the result of comparing an original and a changed document.

Tools pass if they detect all edits and moves, and fail if they miss any moves, producing cluttered outputs.

Each category has 3-4 tests represented by bars. Bar length means test difficulty, bar color is green (pass) or red (fail). For example:

means the tool passed the easy and medium tests but failed the hard test.

Tests are grouped into three categories: list order, section order, and cross moves.

Click any test to view the original markups. Markup presentation is standardized.

Note: TreeDiff is for technology providers, most other listed tools are for end users.
