BUILT FOR REPEATED COMPARISON

From one-off diff to a working comparison workspace.

Compare two versions, analyze a 3–24 file timeline, ask grounded AI questions, then optionally save a sanitized structured report to your account and share a read-only result.

Browser-first source files

Normal source documents remain in your browser during comparison.

Private cloud workspace

Save structured results without uploading the original files or full extracted text.

Ask Change Lens

AI uses structured changes; selected clause wording is sent only after one-time permission.

POPULAR USE CASES

Built around documents people actually receive again and again.

Policies & contracts

Prioritize premium, coverage, exclusions, duties, cancellation and deadlines.
