Vahai
Turn your notes into knowledge you can recall.

Questions
Every question, traced back.
Every question is tied to a citation in your source; if it cannot be traced back, it is thrown away before you ever see it.
Sample study note
“Active recall means trying to retrieve an idea from memory before seeing the answer. Rereading means looking at the information again.”
You close the note and explain the idea in your own words. What are you doing?
- Active recall
- Rereading
- I am not sure — show me the explanation
Study
Graded on meaning, not keywords.
Write in your own words. Vahai scores understanding, not keyword matching.
- Multiple choice
- True / False
- Free response
You can study offline too; your progress syncs when you reconnect.
- Answer
- Active recall
- Why?
- You tried to bring the idea to mind without looking at it. Rereading would mean opening the note and reading it again.
- Evidence in the sample note
- “…trying to retrieve an idea from memory before seeing the answer.”
Fennec
Stuck? Ask Fennec.
Ask about the question you’re stuck on or chat freely; Fennec grounds its answers in your source.
- Give me an analogy
- Explain this like I’m 12
- How does this differ from a similar concept?
Oasis
Progress without punishment.
Every study session drops a little rain on the desert. A missed day rests your oasis — it never kills it.

Who it’s for
It adapts to whatever you study.
Choose your field when you first open the app; your starting suggestion is built around it.
University and high school students
High school: “Pick one topic from a lesson, such as a concept, rule or short process.”
Undergraduate: “Start with one concept from your next lecture or a short slide section.”
Exam and test prep
Feel more prepared for an exam: “Start with one topic you find difficult; you do not need to upload your whole archive at once.”
Medical and law students
Medical / health: “Start with one mechanism or a group of concepts you often confuse.”
Law: “Choose one rule and its conditions; try explaining how it applies to an example.”
Language learners
Language learning: “Choose a short passage with vocabulary or a grammar pattern you want to practise.”
Anyone revising from recorded lectures or scanned notes
“An audio or video recording”
“Photos of my notes”
