What is MathCard?

MathCard turns plain text and mathematical expressions into image cards that are easy to post on X.

Basic Workflow

  1. Write text and formulas.
  2. Enter LaTeX code, select the part you want to display as a formula, and click Math.
  3. Click Copy Image.
  4. Click Open X.
  5. Paste the copied image into the X composer and post.

Supported Formula Syntax

[math]...[/math]

[math]
x^2+y^2=z^2
[/math]

$$...$$

$$
x^2+y^2=z^2
$$
  • Enter LaTeX code, select the part you want to display as a formula, and click Math. If no text is selected, an empty math block is inserted.
  • Both syntaxes are parsed into the same internal math block.
  • Full Markdown is not supported.

Common LaTeX Syntax

PurposeInput
Powerx^2
Subscripta_n
Fraction\frac{a}{b}
Square root\sqrt{x}
Greek letters\alpha, \beta, \pi
Sum\sum_{k=1}^{n} k
Integral\int_0^1 x^2\,dx
Limit\lim_{x \to 0}

Matrix


\begin{pmatrix}
a & b \\
c & d
\end{pmatrix}

Aligned equations


\begin{aligned}
a+b &= c \\
d+e &= f
\end{aligned}

Rendered Examples

x2+y2=z2x^2+y^2=z^2
ab+x\frac{a}{b} + \sqrt{x}
∑k=1nk\sum_{k=1}^{n} k
(abcd) \begin{pmatrix} a & b \\ c & d \end{pmatrix}
a+b=cd+e=f \begin{aligned} a+b &= c \\ d+e &= f \end{aligned}

Tips

  • Multiple formula blocks are supported.
  • [math]...[/math] and $$...$$ may be used in the same card.
  • Invalid formulas do not crash the application.
  • Very long formulas may need to be shortened to fit the card cleanly.
  • The exported PNG matches the visible CardPreview.
  • Save PNG and Copy Text are optional secondary actions.
