HippoCampusSpaced repetition, done properly
Learn it once. Keep it for good.
Answer in your own words, learn hands-free on a walk, or describe any subject and get a full course — then spaced repetition keeps it there.
Cell Biology Fundamentals
4 / 21What role does the folding of the inner mitochondrial membrane play in ATP production?
YOUR ANSWER · FROM VOICE
It increases the surface area for the electron transport chain…
What you had and what you missed
You named the surface-area idea correctly. Add that the folds are cristae, giving ATP synthase more room to work.
What you can do here
Answer in your own words
No multiple choice. Say it out loud or type it the way you'd explain it to a friend — then get told exactly what you had and what you missed.
Learn with your phone in your pocket
Start a Smart Session, lock the screen and go for a walk. It reads the questions, you answer out loud. Completely hands-free.
Scan a page, get the questions
Point your camera at a book chapter or your own notes. Seconds later it's material you can actually be tested on — nothing to type in.
Don't just learn it — keep it
Every answer sets its own next review, days or months out. What you learn this week is still there next year, not gone by Friday.
Questions that fit the subject
Pin the country on a map, put the steps in order, name the structure. The question type follows the material instead of forcing everything into a flashcard.
A course on whatever you want
Any subject, any depth. Describe it in a sentence and HippoCampus writes the course, the chapters and the questions around it.
How it works
Step 1
Describe what you want to learn
A brief in your own words, or your own notes and files. The course gets written from it, chapter by chapter.
Step 2
Review before anything is scheduled
Generated questions land in a review table first — edit, drop or re-file them, then approve the set.
Step 3
Answer one card at a time
Speak, type or think. The answer is graded, the interval is stated, and the next card is already chosen.
What costs money
Free
Nothing to pay
Smart Sessions, with an ad before each oneCourses you write yourself, Discover additions, and everything already in the libraryCourse generation, at half a Pro user’s monthly allowance

Generous monthly limits, not a per-course charge.
The full monthly generation allowance — twice the free allowanceSmart Sessions with no adsThe same generation tools (brief, notes or a file, map courses, regenerate and retry), on that higher allowance
Worth asking
Is this the same subscription as the phone app?
Yes. Pro follows your account, so buying it in the iOS app unlocks generation on the web too.
What exactly is paid for?
Pro is about allowance and comfort, not access. Free accounts can generate courses and review everything they already have — on half a Pro user’s monthly allowance, with an ad before each Smart Session. Pro doubles the allowance and removes the ad.
What happens when the trial ends?
Generation continues on the free allowance and Smart Sessions start with an ad. Pro removes the ad and doubles the allowance. Every course and question you already made stays in your library.
