LaTeX lets you display mathematical equations and scientific notation directly in your question titles — no image uploads needed. It renders on both the presenter view and all participant devices simultaneously.

​
Add LaTeX to a question title

There are two ways to enter LaTeX in the canvas editor.
1

Using the LaTeX dialog (recommended)

Open the canvas editor and click the LaTeX button in the toolbar.The LaTeX icon highlighted in the canvas editor's text formatting toolbar, above a question titleType your equation in the dialog box — there’s no need to wrap it in $ signs. Click Insert to render it in your slide.The LaTeX dialog box with an equation typed in, and Close and Insert buttons below it

Typing directly in the title

Click into the question title field and wrap your equation in $ signs — for example, $x^2 + y^2 = z^2$. Press space or click outside the text box, and it converts to rendered LaTeX automatically.

​
What LaTeX syntax AhaSlides supports

AhaSlides uses KaTeX to render LaTeX. This covers most standard equations and scientific notation, but it does not support full LaTeX document syntax. Commands like \documentclass or \begin{document} won’t work — write only the equation part.

​
What happens with invalid LaTeX

If you enter invalid LaTeX syntax, the editor shows an error message rather than breaking your slide. Fix the syntax and the equation renders correctly, without affecting your presentation flow.
