View key capabilities & tips
Key capabilities:
- Pixel-level visual diff highlighting changes in contrasting overlay colors
- Synchronized side-by-side dual-pane scroll viewer for rapid inspection
- Detects subtle font substitutions, formatting shifts, and deleted text clauses
- Runs completely in browser memory without uploading sensitive contracts or plans
Tips:
- Ensure both PDF documents have matching page dimensions and orientations for optimal alignment.
- Use the diff sensitivity slider to filter out minor antialiasing artifacts from actual text changes.
- Review high-risk sections (e.g., pricing tables and indemnity clauses) carefully in side-by-side view.
