Overview

AI flashcard and study app from Hong Kong: generates flashcards and quizzes from notes, slides and PDFs with spaced repetition; two co-founders.

Operator: Jason Chan and Calvin Cheung (co-founders). Website: https://memo.cards/

Estimated split: about 85% of the work automated, 15% human.

Realistic income

Co-founder Jason Chan said in interviews around December 2024 that Memo AI was making about $29,000 in monthly recurring revenue. That figure is now old. This figure is operator-reported, not independently verified, and may be out of date. This is one operator’s result, often after months or years of work, and doesn’t predict yours. Check the live source — numbers change.

Risks

The figure is from late 2024 and may have changed.
Many AI study apps (Quizlet, Knowt and others) compete.
Students are price-sensitive and cancel after exams.
Startup cost and time to first dollar are not disclosed.
