Overstrike compares two versions of a document and produces a redline PDF: deleted text struck through in red, inserted text underlined in blue. Everything happens on your device.
Use Overstrike
- Add the earlier version to Original and the newer version to Revised.
- Select Compare Documents.
- Select Export PDF or Save Redline PDF and choose a location.
Supported files and limits
- Use text-based PDF or Word (.docx) files. Run OCR on scanned PDFs first, and convert legacy .doc files to .docx.
- Monthly Core compares ordinary main-body Word paragraphs. Pro Tools adds tables, headers, footers, footnotes, endnotes, and numbered lists.
- The App does not compare comments, tracked-change markup, text boxes, images, or layout objects.
- The redline is a re-typeset text comparison, not a copy of the original layout, images, tables, or pagination. Reordered or heavily rewritten text may appear as a larger replacement.
- Export an unlocked copy before comparing a password-protected file.
Overstrike is a review aid, not legal advice or a certification. Review the output against both source documents before relying on or sending it.
Privacy
The App compares documents on your device and does not upload them. It reaches the network only through Apple's StoreKit services for purchase loading, purchase, verification, management, and restore. The App keeps no document history. Your backups, cloud settings, and copies remain your responsibility.
Purchases
Monthly Core is required to compare and export. Pro Tools is a separate one-time purchase whose four features work only while Monthly Core is active. If Core ends, Pro Tools stays owned and works again when Core restarts.
Apple controls purchase, renewal, cancellation, restore, and refund decisions. Manage Monthly Core in your Apple Account settings or contact Apple Support. Company does not directly control Apple billing or your Apple Account.
