How the eye sees
Light from an object enters the eye through the clear cornea, which bends it the most. The lens then fine-tunes the bend so the light lands sharply on the retina at the back.
Small muscles make the lens fatter for near objects and thinner for far ones. The retina turns light into signals, and the optic nerve carries them to the brain.

exam!
Ten papers. Zero excuses.
Lined, dotted, squared, Cornell and six more, in white, yellow or black. Change any page's paper later.
Less hunting, more revising.
Dark cards for late nights, notes beside the card, search that reads your handwriting, and friends who can watch you work.
Late-night cards
Turn a card dark when the room is. On a card, tap the button (More), then Card colours, and pick Match iPad, Light or Dark.
Notes beside the card
Open a card on one side and your notebook on the other. Or drag My notes onto any spot, and that spot gets a notebook of its own.
Find what you wrote
Search reads your handwriting on the iPad itself, with no internet, along with typed text and the text of your PDFs.
Voice on. Page on.
In a private café, talk with your voice and share the page you are writing on. Friends see each stroke the moment your pen lifts.
Circle it. Copy it.
In testing now. Hold a card's title with one finger and circle any part with another. The box snaps to the lines, tables and pictures inside your circle. Copy it, or keep it in Clips and put it on any page later.
An acid gives hydrogen ions in water. A base takes them up.
The pH scale runs from 0 to 14. Below 7 is acidic, 7 is neutral and above 7 is basic.

Lecture in. Card out.
A card is a study page saved as one HTML file (a web page file whose name ends in .html). Lekhin opens it, and you write on it with Apple Pencil. You don't write any code: an AI chat makes the file for you.
- Your lecturea PDF, slides or your notes
- Any AI chatChatGPT, Claude, Gemini or another
- Lekhinon your iPad
1Make the card
- Open any AI chat, on your computer or on your iPad.
- Attach your lecture PDF, or paste your notes into the chat.
- Copy the prompt below and send it with your lecture.
- You get back one file whose name ends in .html. Download it. On an iPad, Safari puts it in Files, in the Downloads folder. If the card opens instead, tap Share, then Save to Files.
Only code on the screen? Ask: “Give me this as a file I can download.” On a computer you can also paste the code into Notepad and save it as “card.html”, with the quote marks. On an iPad, ask again or use a computer.
Want changes? Ask in the same chat, for example “Make the tables bigger”, then download the new file. It comes in as a new card, and your writing stays on the old one, so get the card right before you write on it.
The prompt
Turn this lecture into one study card, as a single HTML file I can download. Put everything inside that one file, pictures too: no links to other files, and no fonts or pictures from the web. Use a clear title, short sections with headings, short points, tables and simple diagrams, and put the key facts in bold. Leave some space to write by hand, and make it easy to read on an iPad.
2Put it in Lekhin
On your iPad. In Lekhin, open the Library or a folder. Tap + at the top right, then HTML card, and pick your file (look in Recents or Downloads). It is copied into that folder and opens. One file at a time, up to 25 MB.
Made it on a computer? Send the file to your iPad, for example with AirDrop, iCloud Drive or email, and save it to Files. Then add it as above.
From your computer. Drop the file into Card Sync. Your iPad picks it up the next time you open Lekhin, or when you pull down on the Library. How Card Sync connects
3Write on it
Write over the card with Apple Pencil. Tap the book button at the top right (My notes) for a notebook that belongs to this card.
To take out a card you added, hold it in the Library or folder where you added it, then tap Remove card. It goes at once. Your file in Files stays.
?If it looks wrong
- “This file is not an HTML card.”
- The file is not a web page. Ask the AI again for one .html file.
- “This card is bigger than 25 MB, so it was not added.”
- Ask the AI to make the pictures smaller, or split the lecture into two cards.
- Your file is grey and can't be picked
- Its name does not end in .html. Ask the AI again for an .html file.
- “This file could not be read.”
- Download the file again and pick the new copy.
- Pictures are missing
- Pictures saved next to the file do not come with it. Ask the AI to put the pictures inside the file, or to draw the diagrams.

Questions
Answered before you could ask.
Which iPads does it work on?
Lekhin Notes is made for iPad only. It runs on any iPad with iPadOS 16 or later, and Apple Pencil is the best way to write. On iPads whose Pencil can hover, the laser pointer follows the Pencil before it even touches the screen.
Do I need an account?
Not for your notes. The Study Café signs you in on its own without an email or password, so all you choose is a café name.
Does it work without the internet?
Yes. Notebooks, cards, the pens, PDFs and handwriting search all work offline. The café and its voice rooms need the internet.
Can I bring my notes from another app?
Yes. Export your notebooks from the old app as PDFs, then use Import PDF in Lekhin and keep writing on them.
How much will it cost, and when can I get it?
Lekhin Notes is coming soon to the App Store. The price and the download link will be on this page on launch day.
