// The idea
Import your notes. Thoth turns them into summary sheets, flashcards and a quiz, then hands them back at the exact moment you were about to forget.
Fewer hours rereading. More of it sticks.
Three tools, three jobs. Reread, remember, apply.
0
credits to review, no matter what.
Your tutor, one tap away.
Ask in the middle of a review. One credit per message.
Testing yourself fixes a memory far better than rereading.

How it works
A PDF, a photo of the board, a web page, a recording of the lesson or pasted text. If your PDF already contains its text, it's read on your device and nothing is sent.
A language model reads all of it, not a summary or a page address. If there's something it couldn't read, it tells you.
One card for each idea you need to be able to explain, a structured summary sheet, a quiz to apply it. Formulas are set properly, diagrams are drawn.
Each answer you rate moves the next review: D+1, D+3, D+7, D+14, D+28, or the SM-2 algorithm, which adapts to each card.

// What you remember
It all starts from your class, in your teacher's order and your teacher's words. That's what will be on the test.
From scattered notes to an orderly memory, and all you do is import them.

Current card · Where does photosynthesis take place?
Why is it called the "dark phase"? Does it happen at night?
No, that's a classic trap. It's called that because it doesn't use light directly. It mostly runs during the day, on what the light phase supplies:
Light phase
ATP + NADPH
Calvin cycle
CO2 fixed
Glucose

Stuck? Ask Thoth.
It opens on top of your review, so you never leave it, and starts from what's on your screen.
- It sees what you're reviewing.
The card, quiz or sheet on screen is part of the question.
- It reads your photos.
An exercise, a diagram from the board, a textbook page.
- It knows your level.
High school or university, it adjusts its explanations to what you've told it about yourself.

// Why "Thoth"
In ancient Egypt, Thoth is the god of writing and knowledge. That's where it all starts: someone writes, someone else learns.
Test yourself instead of rereading.
Rereading feels like knowing. Searching for the answer in your head, even if you get it wrong, fixes the memory far more firmly.
Review at the right time.
Going over an idea just before you forget it takes less effort, and lasts longer, than ten rereads the night before.
Your class, not the internet's.
It all starts from what your teacher taught, in their words and their order.
Nothing arbitrary.
As long as you have credits left, nothing stops you. And reviewing never costs any.

How do I make study notes with AI?
Import your notes into Thoth: a PDF, a photo of the board, a web page, a recording of the lesson or pasted text. It builds a summary sheet, flashcards and a quiz from your own material. All that's left is to review.
What is spaced repetition?
It means going over an idea just before you forget it, at longer and longer intervals: the same day, then 1, 3, 7, 14 and 28 days later. Each reminder strengthens the memory and takes less effort than ten rereads the night before.
Which subjects does it work for?
Any subject you learn in class: sciences, languages, history, law, medicine, economics. Formulas and diagrams are handled.
Does reviewing use credits?
No. Credits only pay for what the AI produces: cards, summary sheets, quizzes, coach replies. Reviewing, writing a card by hand or browsing your library costs nothing.
Do my notes stay private?
Yes. Only you can see them, except what you choose to share in a class. You can export or erase everything from the settings.
Can I stop whenever I want?
Yes. You cancel your subscription from the settings, and it stays active until the end of the period you've already paid for.
What about iPhone?
Thoth works in your phone's browser and can be added to your home screen. An iPhone app is on the way.
