For math tutors and math teachers

An online whiteboard that handles graphs, formulas, and the student.

Teach math without jumping between a PDF, a calculator, a quiz and a video call. Lucyboard keeps everything on one board.

Lucyboard whiteboard with a function graph, LaTeX formula, and lesson notes.

Math lessons should not be a tour through five apps.

You are teaching a quadratic function, so you need a formula, a graph, a worked solution, a quick check-in, and a link for the student. If those live in four tabs, the student loses the thread after five minutes. Lucyboard puts them in one place — one board, one link, in the browser.

A quadratic function graph drawn next to the problem text.

Draw the graph right where the problem lives.

Students understand a function better when they see its shape next to the task. You type f(x) = x² − 4x + 3 in the same view as the problem — not in a separate Desmos tab that you have to screenshot afterwards. When you change a parameter, the student sees the minimum move.

Steps of a solution with LaTeX formulas written next to each other.

Write formulas step by step, not in chat.

LaTeX in a chat window is gone in an hour. On the board, you write the formula, leave space, write the next step, and the student sees the thinking, not only the answer. If they make a mistake somewhere, you leave a note next to that specific step — not at the bottom of the whole solution.

A marked mistake at a specific solution step with a short note.

Mark the mistake at the exact step.

The student lost a sign when rearranging. Instead of rewriting the whole solution, you mark that one step, add a short note about what to fix, and you have a recap ready for the next lesson. That is the real difference between a shared board and a piece of paper nobody will look at again.

A short quiz on derivatives next to the lesson notes.

Check understanding without opening another app.

After explaining the derivative, you add a short quiz: one question next to the notes, four options, the student clicks. You see whether to keep going or go back. No Forms link in chat, no Kahoot setup, no three minutes lost on logistics.

A link to the board in chat and the student view after joining without an account.

Send a link. The student joins with no account.

No more "download the app, create an account, confirm your email, join the class". You paste a link in the chat, the student clicks, and they are on the same board as you. If they want to come back to the lesson in the evening, the link still works.

What Lucyboard does not replace.

If you need any of these, this is not the right page for you:

A full LMS with modules, grading, and class reports.
A testing system with a question bank and ranking (Kahoot, Quizizz).
An offline drawing app for tablets (Explain Everything).
A scientific calculator as a standalone application.

Open a board and paste your first problem.

You do not need to build a lesson from scratch. Paste the problem you have for the next class, walk through the solution, and the student joins from a link. It will take you less time than picking the colour of sticky notes in another tool.

Frequently asked questions

Yes. You write formulas in LaTeX syntax and Lucyboard renders them in real time. We use the same syntax as most university textbooks, so if you write \frac{}{} or \sqrt{}, it works.

Yes. As you draw or modify the graph, the student sees every cursor move. The same applies to notes, formulas, and PDFs. Everything syncs in the browser, without lag.

Yes. You drop a PDF, a photo of a notebook, or a worksheet as a board element. You write the solution next to it, not in a separate notepad. After the lesson, you export the whole thing as a PDF with the annotations preserved.

It works in the browser, so yes — iPad, Android tablet, Chromebook. A stylus works as a stylus. But if you need offline mode or a native iPad app, this is not the right tool.

Yes. Lucyboard has tools for physics, chemistry, languages, flashcards, quizzes, short recaps. The page you are reading is about math only, because that is the specific intent you came in with. Other use cases have their own pages.

The Basic plan is free forever, with up to 10 permanent boards. Pro costs $10 per user per month (or $6.99 per user per month on the yearly plan) and adds full PDF / SVG export, unlimited boards, and no ads. Running a school or a team? Write to us, we have a schools and teams offer.
