We don't do the work for you.
We make it stick.
Tigrus is a study engine built on one belief: real learning happens when YOUR brain does the retrieving. The AI handles everything around that moment — and never replaces it.
WHAT WE REFUSE TO BE
AI that studies for you.
Chatbots hand you finished answers. It feels like progress — until the exam, when the chat log stays home and your memory shows up empty. Tigrus never does the homework for you, by design.
- No essay ghost-writing
- No answer-dumping
- No illusion of progress
WHAT WE BUILD INSTEAD
AI that makes YOU sharper.
Every tool exists because peer-reviewed research says it strengthens memory: retrieval practice, spacing, elaboration. Tigrus does the busywork — writing cards, timing reviews — so you can do the learning.
- Retrieval practice, +50% retention
- Spaced repetition, +46% long-term recall
- Your notes as the source of truth
Organized like a library,
four levels deep.
Shelves group your subjects.
A shelf is a semester, an exam, a goal. Everything for it stands together — five classes, one glance.
FALL SEMESTER
Notebooks hold your classes.
One notebook per course or topic. Pull it off the shelf and its sections are right there — nothing to hunt for.
Cell Biology
3 sections · 14 pages
Sections split the units.
Chapters, weeks, themes — sections keep a big notebook navigable, and every page knows exactly where it lives.
Pages carry the knowledge.
Notes live on pages — and every deck, quiz, and map you generate stays wired to the page that created it. Forever.
