Overview
Use the Math Equation block to write, generate, and display a mathematical formula in your notes. Enter a valid KaTeX expression, or describe the formula and ask Lara to create one.
Edit the formula in Math Editor after it’s generated. Use the block for everything from a simple equation to a matrix or another expression you want to keep with your notes.
When to use it
Add a formula to support an explanation in your study notes.
Keep equations and calculations alongside a project plan or technical note.
Write a formula you want to reuse or revise later.
Generate a mathematical expression, such as a matrix, from a description.
Features and settings
Setting
Add or update a formula

Built in
Generate a formula with Lara
Choose “AI,” describe the formula in “Describe the formula,” and select “Generate formula.” Lara creates a LaTeX formula that you can edit afterwards.
Built in
Edit your expression
Review and adjust the formula in “Math Editor,” then select “Done.”
How to use it
Add the block
In the editor, type / and search for “Math Equation,” then select it.
Open the editor
Select “Click to add math equation” to open “Math Editor.”
Choose how to create the formula
Select “Manual” to type a KaTeX expression, or “AI” to describe the formula you want.
Generate or enter the expression
For AI generation, enter a description and select “Generate formula.” In Manual mode, type your expression in the math editor.
Finish and revise when needed

Tips · Limitations
Tips
Use a valid KaTeX expression when entering a formula manually.
Describe the structure you want clearly when asking Lara to generate a formula.
Review AI-generated expressions in “Math Editor”; you can edit the formula afterwards.
Use the “Basics,” “Calc,” “Greek,” “Logic,” “Arrows,” and “Snippets” groups while working on an expression.
Limitations
The equation accepts up to 4,000 characters.
The expression must be valid KaTeX to be entered as a formula.
Frequently asked questions
How do I add a math equation to my notes?
Type / in the editor, search for “Math Equation,” and select the block. Open “Math Editor” to enter or generate a formula.
How do I write a formula in the equation block?
Select “Manual” in “Math Editor” and enter a valid KaTeX expression.
Can Lara generate a math formula for me?
Yes. Select “AI,” describe the formula, and choose “Generate formula.” Lara creates a LaTeX formula that you can edit afterwards.
Can I edit an equation after adding it?
Yes. Open the block’s “Math Editor,” revise the formula, and select “Done.”
Why isn’t my formula accepted?
The expression needs to be valid KaTeX. If Lara does not return a valid mathematical expression, review the description or enter the formula manually.
