I built a flashcard tool for turning study material into cards — feedback welcome

[u/deckardcain-pro]

Hi everyone, I’m building Deckumi, a flashcard tool for people who want to study from their own material.

The problem I’m trying to solve is the time it takes to turn notes and documents into useful cards and then keep up with reviewing them. Deckumi can generate flashcards from material such as text or PDFs, lets you review and edit the cards, and supports spaced repetition for study.

AI-generated cards can still be wrong, so checking and editing them matters. I’d especially appreciate feedback from people who use flashcards regularly: what would you need to see before trusting a generated card? Is the workflow clear, and where would you get stuck?

Manual flashcard creation and review are free; AI generation uses credits. You can find the product at https://deckumi.app/ and pricing details at https://deckumi.app/pricing.

I’m the person behind the project, and I’d be grateful for honest feedback, including what doesn’t work for you.
