Cue — Free Study App for High School Students | Flashcards, AI Tutor, Math Practice & Study Games

Hi, I'm Cue.
Free for students

We help youactually rememberwhat you study.

Not just recognize it. Recall it on demand.
Cue uses cognitive science to make studying actually work.

Traditional studying is perfect

Re-reading is a lie

You feel like you know it. But can you actually recall it without looking? Probably not.

Cramming backfires

Last-minute studying gets you through the test. Then poof — gone in 48 hours.

🖍️

Highlighting is useless

Decades of research confirm it: pretty colors don't build memories.

Three steps. Backed by science.

01

See a question

A prompt appears. No multiple choice. No hints. Just you and the challenge.

02
✍️

Write from memory

Type what you know. The struggle is the point — it's building neural pathways.

03

Compare & level up

See the answer. Rate yourself honestly. Cue's self-calibrating algorithm figures out exactly when to show it again — based on your memory, not an average.

Not guesswork. Peer-reviewed research.

Spaced Repetition

Review right before you forget. The FSRS algorithm predicts your memory decay with scary accuracy.

Ye et al., 2024

Desirable Difficulty

Easy learning doesn't stick. The productive struggle of recall builds lasting memories.

Built to make studying actually work

Self-Calibrating Algorithm

Cue doesn't use a one-size-fits-all schedule. It tracks how your actual recall compares to predictions and tunes your review intervals automatically — tighter when you're struggling, wider when you're nailing it.

AI Tutor

Stuck on a concept? Ask Cue. It explains like a patient teacher — no jargon.

1,000+ Pre-Built Cards

Curated library across all major high school subjects. Ready on day one.

Multiplayer Study Battles

Race friends on the same flashcard deck in real time. A live join code gets your whole class in instantly. Learning is more fun with stakes.

Memory Analytics

Retention heatmaps, study streaks, and weak-spot detection. Know exactly where to focus.

Classroom Tools

Teachers can assign decks, track class mastery, and print progress reports.

AI Math Practice

Real-time problem generation across algebra, geometry, statistics, and more. Every problem is unique — no stored cards, no repeats. Just focused practice that adapts to where you are.
