Collie | AI Handwriting Eraser

"I wish I could redo that worksheet I already wrote on..." "I want to make a test with just the problems I got wrong..." "I've lost track of which problems I still can't solve..." Collie is a study support app that solves all these problems at once. --- ■ AI Removes Handwriting Cleanly Just take a photo of your worksheet or study material, and AI automatically detects and removes only the handwritten marks. Printed text stays intact, so you can redo problems as if the sheet were brand new. No more erasing by hand and making copies. ■ Create Tests from Missed Problems Only Simply mark the problems you couldn't solve, and create an original test from your weak points with a single tap. Swipe to intuitively select which problems to include. Tests are automatically laid out in A4 format, ready to print. ■ Repeat Until You Get It Right Collie never forgets your weak problems and keeps presenting them until you master them. No more wondering which problems you still haven't solved. Review history is tracked per problem to fully support your progress. --- ■ Perfect For - Parents supporting their child's studies - Those who want to reuse printed worksheets and study materials - Those who find managing weak problems tedious - Those who want to build an efficient review cycle ■ Key Features - AI Handwriting Removal: Erase handwriting just by taking a photo - Scan Management: Organize scanned worksheets by subject - Weak Problem Marking: Select problem areas to flag as weak points - Test Creation: Auto-generate original tests from weak problems only - Repeated Practice: Keep presenting problems until mastered, with review history - Image Editing: Cropping, manual eraser, original view - PDF Export: Export and print created tests as PDF - Continuous Scanning: Efficiently scan multiple pages ■ Pricing - 7-day free trial included - Monthly and yearly plans available (yearly is a better deal) - Cancel your subscription anytime Terms of Use: https://gist.github.com/souchida/9d243dcbd9875a33c573388acbec8bb0 Privacy Policy: https://gist.github.com/souchida/dc8ea86670743e7f1d10d6610cfcc212
