How it works
- 01
Upload anything
PDFs, EPUBs, links, articles. If you can read it, Cheki can work with it.
- 02
Cheki builds the questions
Not flashcards. Real questions that probe comprehension, connect ideas, and expose gaps.
- 03
Review on your schedule
Spaced repetition surfaces what you're about to forget — before you forget it.
What makes it different
Beyond the
flashcard.
Most tools ask you to recognise the answer. Cheki asks you to produce it. The difference is the gap between feeling like you know something and actually knowing it.
Deep questions
Short-answer, multi-step, and Socratic prompts — not just multiple choice.
Spaced review
A scheduler that learns from your recall patterns and surfaces material at the right moment.
Streak & habit
Progress shown through numbers, not congratulations. Knowledge compounds quietly.
Any format
PDFs, EPUBs, web links, articles. One upload flow regardless of source.
