AI to
memory
Turn AI answers into memory
ChatGPT and Claude can explain almost anything. ouou helps you save the parts that matter as flashcards, then brings them back when they are useful to review.
- 1 Learn from an AI answer, video, article, or note.
- 2 Save the ideas worth remembering as front/back cards.
- 3 Practice a few minutes when ouou brings them back.
- 4 Remember the knowledge months later.
Turn what you learn into cards
Ask AI, import a CSV, or write by hand. Your decks work the same either way.
- Ask ChatGPT, Claude, Gemini, Perplexity, or another assistant for cards in ouou's front/back format.
- Paste the useful parts into ouou, or connect Claude for a direct workflow.
- AI drafts fast; ouou stores, schedules, and reviews the knowledge.
You: "Make 5 ouou cards from this explanation of why seasons happen." front,back "Why do seasons occur on Earth?","Earth's axis is tilted by about 23.5 degrees..." ...
- Bring decks from a spreadsheet or CSV export.
- Two columns: front, back.
- Import in seconds, review the same day.
front,back "What is pressing?","Win the ball back by closing the player down" "hola","hello" "Big-O of binary search","O(log n)"
- Type a front and a back. Done.
- Markdown for structured answers.
- Tag cards so you can filter later.
