How It Works
1. Upload Documents
Drop in two Word documents. The original and the revised version. No track changes required.
2. Change Analysis
Every clause is checked. Material edits are flagged. Formatting stays out of the way.
3. Download Redline
Get a clean redlined document with native Word track changes plus short change notes linked to exact edits.
What Makes clausul Different
Traditional document comparison shows every change equally. That's the problem.
The Old Way
- x 200+ changes to review manually
- x Formatting noise mixed with real changes
- x Moved paragraphs shown as deleted and re-added
- x No way to know which changes actually matter
With clausul
- ✓ Material changes surfaced first (money, dates, liability)
- ✓ Formatting sorted separately: "+14 formatting edits"
- ✓ Moved paragraphs detected, not marked as delete+insert
- ✓ Change notes show what changed and why, with links to exact edits
