Braintain

Free flashcards that put a picture on every card

A picture and audio on every card

Every BrainPod card has its own picture, an example sentence and recorded audio, giving your memory a visual and auditory hook instead of just text.

Spaced repetition that sticks

Reviews are scheduled just before you would forget a card, so recall strengthens with minimal daily effort rather than last-minute cramming.

Ready-made BrainPods

47 ready-made BrainPods span languages, science, everyday English and more, each organized into levels so you can start where you are.

Mira, your AI coach

Premium adds Mira, an AI coach that reads your study history to give a Learning Score, highlight strengths and weak spots and propose a plan for today.
