Text to LaTeX

Describe an equation in plain English and get the LaTeX, typeset live and ready to copy. Free, no sign-up. Say what you mean (“integral of x squared from 0 to 1”) and paste the code straight into Overleaf or any document.

Describe your equation

How it works

Type what the equation is, in plain English. Name the parts you care about (the limits of an integral, the size of a matrix).
The tool writes standard LaTeX and typesets it live so you can check it.
Press Copy LaTeX and paste the code into Overleaf, a .tex file, or anywhere that renders maths.

Examples

Common descriptions and the LaTeX they produce.

The quadratic formula

x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}

x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}

Sum of the first n integers

\sum_{i=1}^{n} i = \frac{n(n+1)}{2}

\sum_{i=1}^{n} i = \frac{n(n+1)}{2}

Definite integral of x squared from 0 to 1

\int_{0}^{1} x^2 \, dx = \frac{1}{3}

\int_{0}^{1} x^2 \, dx = \frac{1}{3}

Limit definition of the derivative

f'(x) = \lim_{h \to 0} \frac{f(x+h) - f(x)}{h}

f'(x) = \lim_{h \to 0} \frac{f(x+h) - f(x)}{h}

A 2 by 2 identity matrix

\begin{pmatrix} 1 & 0 \\ 0 & 1 \end{pmatrix}

\begin{pmatrix} 1 & 0 \\ 0 & 1 \end{pmatrix}

Euler's identity

e^{i\pi} + 1 = 0

e^{i\pi} + 1 = 0

Standard deviation of a population

\sigma = \sqrt{\frac{1}{N}\sum_{i=1}^{N}(x_i - \mu)^2}

\sigma = \sqrt{\frac{1}{N}\sum_{i=1}^{N}(x_i - \mu)^2}

Bayes' theorem

P(A \mid B) = \frac{P(B \mid A)\,P(A)}{P(B)}

P(A \mid B) = \frac{P(B \mid A)\,P(A)}{P(B)}

Frequently asked questions

Is this text-to-LaTeX converter free?

Yes. Describe an equation and get the LaTeX with no account and no payment. There is a fair-use daily limit to keep it free for everyone; sign up free for a higher allowance.

How do I use it?

Type what the equation is in plain English, for example 'the integral of e to the x times sin x from 0 to pi'. The tool writes the LaTeX, shows it typeset, and gives you a Copy button.

Where can I paste the LaTeX?

Anywhere that renders LaTeX maths: Overleaf, a .tex document, Jupyter, many wikis and forums, and chat apps that support maths.

Does it handle fractions, integrals and matrices?

Yes. It writes standard LaTeX, so fractions (\frac), integrals (\int), sums, roots, Greek letters and matrices (pmatrix) all come out correctly. Describe the structure and it builds it.

What if the result isn't quite right?

Rephrase the description to be more specific, for example naming the limits of an integral or the size of a matrix, and convert again. You can also tidy the code by hand in the free equation editor.

Prefer to type the LaTeX yourself?

Use the free LaTeX equation editor to write and preview LaTeX by hand, or the LaTeX symbols cheat sheet to look up a command. Got a whole page of handwritten maths? Turn it into LaTeX with handwriting to LaTeX.
