Sculpt your memory.
Stored privately.
Ninuli turns your notes into smart flashcards using on-device AI. Master any subject with adaptive spaced repetition—all secured in a private on-device vault.
Your brain is designed
to forget.
Without active recall, up to 80% of new knowledge vanishes within a week. The standard approach to studying isn't just inefficient—it's biologically flawed.
Notes pile up, never revisited
You highlight, write, and save—but without a systematic way to review them, those notes become an expansive graveyard of forgotten insights.
You review at the wrong time
Re-reading chapters right before an exam creates a false sense of fluency. Once the test is over, the long-term retention instantly collapses.
AI tools surrender your data
Modern study apps leverage AI, but they force you to upload everything to cloud servers you don't control. Your notes, your patterns, and your mistakes become theirs.
Five steps to
durable memory.
Create or generate cards
Type content manually, or paste text and let the on-device AI draft cards for you. Preview and edit every card before saving.
Organize into decks & collections
Group cards into themed decks, bundle decks into collections, and tag items for cross-deck filtering. Assign difficulty levels like beginner, intermediate, or advanced.
Study with SM-2 scheduling
Study due cards, new cards, or your full deck. Rate your recall from Again to Easy, and the SM-2 algorithm calculates the next optimal review date.
Export & import your decks
Export any deck as a plain text file or Anki-compatible .apkg format. Import files from other platforms without creating an account.
Track progress, build streaks
Monitor session summaries, streak counts, daily stats, and card mastery rates. Everything is stored securely in a private on-device vault with zero data sent to external servers.
Everything you need.
Nothing you don't.
Deck & card management
Create, edit, and organize cards with front and back content, tags, and status tracking. Assign custom icons to each deck.

Your knowledge,
your device.
Most AI study tools are hungry for your data. Ninuli was built with the exact opposite philosophy: everything runs and stores locally by default. You own your learning data—fully and forever.
Secured on your device
All cards, decks, reviews, and stats live in a private local vault. Nothing syncs without your explicit action.
AI that never phones home
Card generation runs on a secure, on-device model. Your text is processed entirely on your phone. Nothing leaves your device.
Exports you own
Exported deck files are plain text documents that live wherever you save them. No account is needed, and no server is involved.
Secure credentials
Authentication tokens are stored in the native secure enclave of your operating system, not in standard app storage.
You control sync
Cloud synchronization is optional. If you choose to sync, you decide when. Your data is never uploaded automatically.
Clear answers.
