- You get
- A colour-coded text diff with added/removed counts
- Good to know
- Works best with files under 100 MB (the upload cap); very large files depend on your device's memory. Compares text only — layout, images and formatting are ignored, and scanned PDFs need OCR first. Very long, very different documents may be too slow for word mode; switch to line mode.
- Privacy
- Processed on your device. Nothing is uploaded, stored or logged.

FAQ
Does it compare images or formatting?
No. It extracts the text from both PDFs and compares that, which is what matters for contracts, policies and drafts. Moved images or font changes won't show up.
Word or line mode — which is better?
Word mode pinpoints small edits inside sentences. Line mode is faster for long documents and shows which lines changed.
