Watch a concept
drift away.
This is not a loop. The fading nodes are genuinely decaying as you read — dimming, flickering and orbiting further out the longer they go untouched.
- Forgetting is modelled, not guessed
- Weak concepts surface before an exam finds them
- One click runs the repair and snaps it home
3 concepts drifting. The longer you leave them, the further they go.
The loop
Four steps, and you pick
none of them.
You never build a study plan, choose a mode, or decide what is due. The engine does all four, every session.

The arena
Get it wrong.
On purpose.
Pick the wrong answer and the card cracks open into exactly what the app gives you: the misconception, the idea underneath it, and how to spot it next time.
Go on — pick the wrong one.

Questions
Short answers.
What does it cost?
Nothing. Every feature is free and unlimited — no daily caps, no locked modes, no card required.
Do I need to have notes?
No. Type what you are studying — a topic like “photosynthesis” or “AP World Unit 3” — and AceDecks writes the material for you.
What can I upload?
PDFs, photos of a textbook or your own handwriting, and plain text. You can also import a Quizlet set, an Anki deck, or a Google Doc.
How does it know what I am bad at?
Every answer feeds a mastery model weighing how recently you answered, how hard the question was, how long you took, and how much has decayed since. Miss something and it returns sooner; prove it and it returns much later.
How is it different from Quizlet?
Quizlet holds your flashcards. AceDecks decides what you practise next, and tells you why. You never build a study plan or pick a mode.
What are you
studying?
