What is one important thing the brain does with new information during sleep?
Show the answer
Correct answer: It strengthens and organizes memories
During sleep, the brain continues processing information and strengthens useful memory connections.
Image to flashcards
Photograph a page, get flashcards
Point your camera at handwritten notes, a textbook page, a handout or a slide. PupilBot reads the image, writes flashcards from what's on it, and grades your answers when you practise.

How it works
Take the photo
Use the in-app camera or upload from your gallery. Several pages can go into one study — up to 50.
OCR reads it, the AI writes the cards
The text is extracted from the image, split into topics, and turned into flash cards and questions. About a minute later the study is ready.
Practise, get graded, review on time
Answer in your own words. The AI grades it against the reference, and spaced repetition brings the card back right before you would forget it.
A worked example
The text below is what OCR reads off a photographed page of notes about sleep and memory; the cards and questions after it were built from that text.
This is the demo study every new PupilBot account starts with: a short text, and the flash cards and questions built from it — the same shapes the generator produces for your own pages.
Source text (excerpt)
Sleep is not just a period of rest. While you sleep, the brain continues to process information from the day. It strengthens useful connections, organizes new memories, and makes some information easier to recall later.
Example cards and questions built from it
Front What are the two repeating stages of normal sleep?
Flip the card
Back Non-REM sleep and REM sleep.
In the app you type (or dictate) your answer first; the AI grades it against this reference and explains the difference.
Why can sleeping after learning help?
Show the answer
Correct answer: It can help stabilize and strengthen new memories
Sleep after learning can help the brain stabilize and strengthen newly formed memories.
Front How can sleeping after you learn something help your memory?
Flip the card
Back It helps stabilize and strengthen new memories so they are easier to recall later.
In the app you type (or dictate) your answer first; the AI grades it against this reference and explains the difference.
Tips for a clean read
- Fill the frame with the page and keep the camera parallel to it.
- Even light, no shadow across the text — daylight or a desk lamp beats a phone torch.
- One page per photo. Several photos go into the same study.
- For a slide deck, exporting it to PDF and importing that is faster than photographing the screen.
Frequently asked questions
What kinds of images work?
Photos of handwritten notes, printed pages, handouts, whiteboards and slides. JPEG, PNG and HEIC from a phone are fine.
Does it work with screenshots?
Yes — a screenshot is just an image. For a whole slide deck, exporting to PDF and importing it is faster.
Is my photo stored?
Your uploads are stored privately in your account so the study can be rebuilt; you can delete a study at any time. See the Privacy.
Can I add more pages later?
Each study is built from the pages you gave it. Start a new study for new pages; every study keeps its own mastery scores.
How is this different from a flashcard app?
Anki and Quizlet make you write the cards. PupilBot writes them from the photo — and grades your typed answer instead of asking you to grade yourself.
Is it free?
PupilBot is free to start. A paid subscription unlocks more usage; the web app, the iPhone app and the Telegram bot all use the same account.
