Full description

Everything you learn starts fading the moment you close the book. Knojo brings each idea back the moment before it slips — so what you study actually sticks. Knojo is a spaced-repetition flashcard app built for calm, consistent learning. Turn your notes, articles, and study material into smart flashcards, tie them to real goals like "React interview prep," "Dutch vocabulary," or "Biology exam," and let Knojo handle the rest. Every day it surfaces only the cards that are due — usually a focused five-minute review — and schedules the next one based on how well you remembered. ✨ What you can do with Knojo • Spaced repetition that works: rate each card Forgot, Hard, Good, or Easy and Knojo schedules the perfect next review. • AI-generated flashcards: paste your notes or an article and get clean, study-ready cards in seconds. • Learning goals: organize cards around what you're actually working toward. • Daily review queue: see only what's due today — no endless decks, no overwhelm. • Quiz mode: test recall with AI-powered quizzes. • Streaks & achievements: build a memory habit you'll keep. • One gentle daily reminder: show up for a few focused minutes, then get on with your day. • Your memory coach: guidance that keeps you consistent. Knojo is a dojo for your memory — disciplined, quiet, and designed to fight overwhelm instead of adding to it. Whether you're preparing for an exam, learning a language, prepping for interviews, or just refusing to forget the books you read, Knojo protects what you learn before it fades. Free to start. Upgrade to Pro for unlimited AI cards and quizzes. Download Knojo and start remembering what matters. Flashcards, spaced repetition, memory training, study help, exam preparation, vocabulary practice, and active recall — all in five calm minutes a day.

What's new

Set a daily pace for each goal — Light, Steady or Intense — so your reviews stay a size you can actually finish. Forgot a card? You'll see it once more before the session ends. Done early? Take an optional extra round. Extend your streak and the review ends with a celebration. The card library is now fast on big decks and fully searchable. Fixed: a CSV with an unusual quote mark could silently drop cards on import.
