Compalight - Text Markup

For anyone who redlines on the go. Paste or photograph text, edit freely and see track changes, export to Word or PDF with full markup. Offline, private, no subscription.

Compalight is a specialised text markup tool. Import text from any source — paste, photograph with OCR, or dictate — edit freely, and review every change in a word-level redline.

WHAT YOU GET

1. Three-tab workflow: Original (unlocked/ read-only), Show Changes (word-by-word redline), and Output (your edited text). Switch between tabs with a tap.
2. Word-level change tracking with move detection. Insertions in blue, deletions in red, relocated text in green. Tap any change to revert it individually.
3. Four export formats: plain text, clipboard, as well as comprehensive Word file (.docx), and comprehensive PDF — both with full redline markup, including Original, Changes, and Output sections.
4. Local OCR text import. Photograph a printed page and Compalight recognises the text using Apple Vision. Optional clean-up pass fixes common OCR errors like broken words and stray page numbers.
5. On-device speech dictation. Tap the microphone and dictate text directly into the editor. Powered by Apple Speech, processed entirely on your device.
