A desktop app that bridges passive immersion and active study. Import subtitles from any media, click words for instant lookups, and build your vocabulary with a built-in spaced repetition system.
Import Japanese subtitle files (.srt, .ass) and use Aibou alongside any media player or streaming site. Click any word for an instant dictionary lookup and reading.
A fully integrated Spaced Repetition System based on the SM-2 algorithm. Review vocabulary at the right time, every time โ no external flashcard app needed.
Words you save are called Gems. Organize them into custom Vaults (similar to Anki decks) to keep your study sessions focused on what matters most.
Your Vaults and review progress are securely synced across all your desktop devices via a centralized backend, so you never lose your progress.
Fine-tune subtitle styling, watch session behaviors, review modes, and more. Aibou adapts to your personal learning style, not the other way around.
Track your daily study habits with XP, milestones, and streaks. Stay motivated and build a consistent routine that actually sticks.
