Frequently asked questions
Can this compare scanned handwriting or page layout?
No. It compares extracted text, without OCR or visual layout matching. Reflowed text can create noisy differences.
Is my content sent to a server?
No. Processing runs inside your browser. Optional editor recovery saves a draft on this device only. Read the privacy policy.
Will my original file be changed?
No. Downloaded results are separate copies. Open the finished output before sharing it or deleting an original.
