## What is ReDrill Worksheet Eraser Scan?

ReDrill turns worksheets you've already written on back into clean, blank copies—so your child can solve the same problems again.

Erase pencil answers and red grading marks (circles, checks, red pen) from tutoring printouts, workbooks and exams, then reprint or export as PDF. No need to re-buy the same materials.

WHO IT'S FOR
- Parents preparing children for entrance exams
- Junior-high and high-school students who learn by repetition
- Anyone who wants to redo practice problems

KEY FEATURES
- Erase handwriting & grading marks: removes red/blue writing (red pen, circles, checks) while keeping the printed black text. Tap to protect anything you want to keep.
- Manual brush cleanup: fine-tune leftovers by tracing with your finger.
- Easy scanning: auto-capture with perspective correction—shoot at an angle, get a straight page.
- Two-page split: scan an open book or spread and it splits into left/right pages automatically.
- PDF, print & share: print the edited page, or save/share a PDF that keeps the original page and the edited page together.
- Library with tags: organize saved sheets by name, grade, subject and type. Search, filter and reprint in seconds. Titles auto-named by date.

PRICING (monthly, cancel anytime)
- Free: scanning and editing are free. Watch an ad each time you save, print or share.
- Standard (per month): unlimited ad-free saving, printing and sharing, plus unlimited manual erasing.
- Pro (per month): everything in Standard, with automatic erasing (hands & handwriting) coming in a future update.

Note: fully-automatic erasing is planned for an upcoming update. Today, ReDrill supports red/blue mark removal plus manual brush cleanup.

PRIVACY
- Uses camera and photos for scanning and importing only.
