FAQ

What comparison modes are supported?

Three modes supported: character-level (for precise short text comparison), word-level (for article paragraph comparison), line-level (for code and config file comparison). Options to ignore case and whitespace available.

What does AI semantic comparison mean?

AI semantic comparison checks not just literal differences but identifies semantically similar substitutions. For example, changing "quick" to "rapid" is flagged as semantically similar but differently worded, helping discover implicit modifications.

Can I compare large files?

Yes. Supports text files up to 10MB with efficient diff algorithms for second-level comparison even on large files. Supports uploading .txt, .md, .json, .xml and other text format files.

Can I export comparison results?

Yes. Export as HTML (with styled highlighting), PDF (for printing and archiving), Markdown (for documentation). Can also copy plain text diff summaries.

What scenarios is this suitable for?

Use cases include: code review, document version comparison, contract clause change review, paper revision tracking, translation proofreading, content auditing - any scenario requiring precise text difference comparison.
