One board for your notes, your lessons and your practice. Circle anything and Limepad explains it, checks it or teaches the whole topic, out loud, writing as it goes.

The Moon Landing
Lesson · idea 1 of 6
How it works
Limepad talks you through the topic while it writes it out, pulls in real photos, draws diagrams, and moves the camera across the board as the story goes. The key points are saved for you to revise.
It talks
A natural voice with subtitles, phrase by phrase.
It writes
Notes in its own handwriting, word by word.
It shows
Real photos and drawings: timelines, mind maps, graphs.
It checks
Write on the board with Apple Pencil and it reads your working.
The ✦ button
Write your notes the way you always do. Circle a line, a formula or a page you dropped on the board, tap ✦ on the toolbar and pick what you need. No typing, no copy and paste: Limepad sees what you pointed at.

Board
Explain
What a line of your notes means, in plain words, in a side note right beside it.
Check
Your working, step by step. It finds the exact line that slipped and why.
Next step
Stuck halfway? Just the next move, so you still do the thinking.
Find
Research on what you circled: the key facts, dates and numbers, with a real picture or a diagram.
Teach me
A whole lesson on what you circled, a page of your PDF, or any topic, on the same board.
Practice
Questions from easy to hard on what you studied, with hints when you want them.
Exam prep
Exam-style questions with marks, marked like an examiner would.
Or just talk
Turn the mic on and ask anything out loud. Interrupt it mid-sentence; it answers and carries on.
How smart is Limepad?
A chatbot answers the question you typed. Limepad watches the board with you, so it knows what you wrote, what you pointed at, what you got wrong last week, and how much is left to learn.
It sees your board
It reads your handwriting, your diagrams and the pages you drop in, and knows which writing is yours and which is its own.
It knows what you point at
Circle, underline or draw an arrow: Limepad works out exactly what you meant. Do three things at once and it answers each, in order.
It plans like a textbook
Every lesson is planned first, the way a chapter covers it: 6 to 30 ideas, each taught in depth, then checked for gaps before the recap.
It slows down when you’re stuck
Get a quick check wrong, or ask twice about the same idea, and it goes over it again a simpler way before moving on.
It remembers you
What you found hard last week comes back next time: it links new ideas to old ones and takes extra care where you slipped.
It aims at your weak spots
Practice is marked step by step and every mistake is noted. The next round targets exactly what you missed.
Widgets
A browser, a calculator and your documents float over the page, so you never leave your notes. Ask Limepad to show you something online and it opens it there for you.

Add one in three taps
Tap Widgets on the board’s toolbar.
Pick a browser, a calculator or a document, then tap Add widget.
Drag it by its header, resize it from a corner, or let go near an edge to tuck it away. Each widget gets its own button on the toolbar to show or hide it.
Browser
Any website beside your notes, with SafeSearch always on. Ask Limepad to find a video or a simulation and it opens it here.
Calculator
Trig in degrees or radians, powers and roots, and your last answer, without leaving the page.
Document
A PDF or a photo, page by page. Put any page on the board and ask Limepad about it: it reads the page’s text too.
Your notes, taught
Bring class notes, a textbook chapter, or photos of the whiteboard. Limepad reads it, plans the topic the way a textbook chapter would, and teaches it from start to finish, from your material.
Keep files in folders in your library and Limepad teaches from the whole folder.
Lesson plan
Exercises
Work it out on the board with Apple Pencil, like on paper. Limepad reads every line you write, finds the exact step that slipped, and gives you a hint, not the answer.

Exam prep
Exam-style questions on everything the lesson covered, marked the way an examiner would: where you earned marks, where you lost them, and what to review next.

No. In practice it looks at your working, finds the step that slipped and gives you a hint. In a lesson it explains; it only tests you when you ask for practice or exam prep.
