Math to LaTeX turns a photo, screenshot, or PDF of an equation into clean, ready-to-use LaTeX. Instead of retyping fractions, integrals, matrices, and Greek letters by hand, you upload the image and get markup you can paste into your document. The math OCR runs on our premium AI engine, which is tuned for mathematical notation rather than ordinary printed text, so it reads superscripts, subscripts, and stacked symbols that trip up regular OCR.

It is built for students, researchers, and educators who work with equations every day. If you are copying a formula out of a textbook, a lecture slide, a whiteboard photo, or an older paper that only exists as a scan, the equation to LaTeX workflow saves you from error-prone manual transcription. Both inline expressions and full multi-line derivations are supported, so a single page of dense math comes back as usable markup.

ocr.chat keeps it simple: no signup to try, files auto-deleted after processing, and your original shown side by side with the result so you can confirm every symbol before you trust it. The LaTeX it produces drops directly into a paper, an Overleaf project, or a Markdown file with math support. Free recognition covers printed documents; the math engine is part of the premium AI tier, with paid plans from $5/mo for more pages, batch processing, and API access.

How to math to latex

1
Upload your equation
Drag in a photo, paste a screenshot, or select a PDF page that contains the math you want to convert.
2
Let the AI engine read it
The premium math OCR engine parses the notation, including fractions, exponents, integrals, and symbols, into LaTeX.
3
Review side by side
Check the generated LaTeX against your original image, with low-confidence symbols flagged for a quick look.
4
Copy or export the LaTeX
Copy the markup to your clipboard or download it, then paste it into your paper, Overleaf, or Markdown file.

Common uses

  • Students transcribing textbook and homework equations into typed assignments and lab reports.
  • Researchers converting formulas from older scanned papers into editable LaTeX for new manuscripts.
  • Educators rebuilding equations from lecture slides or whiteboard photos into clean course materials.
  • Writers maintaining Markdown notes or documentation that needs inline and display math.
  • Anyone moving handwritten or printed math into an Overleaf project without retyping it by hand.
  • Tutors and study groups digitizing problem sets to share as editable, searchable text.

Frequently asked questions

The premium AI engine is tuned for mathematical notation and reads most printed and many handwritten equations reliably. Symbols it is less sure about are flagged, and your original is shown next to the result so you can verify before pasting.

It outputs LaTeX markup as plain text. Inline expressions and multi-line equation blocks are both supported, and you can copy the result or download it as a file.

Yes. The LaTeX is standard markup that drops straight into an Overleaf project, a paper, or any LaTeX editor without extra cleanup.

Yes. The generated LaTeX works inside Markdown that renders math with dollar-sign delimiters, so it fits notes apps, documentation, and static sites with math support.

Yes. Multi-line derivations and pages with several equations are converted together, not just a single isolated formula.

Both. Short expressions come back as inline LaTeX, and standalone equations come back as display blocks, so you can drop each into the right context in your document.

Yes. Matrices, arrays, and multi-line aligned derivations are reconstructed with the right environments, keeping rows, columns, and alignment intact rather than flattening them to one line.

It reads chemical formulas, subscripted compounds, and the wide range of symbols found in scientific writing. Anything it is unsure about is flagged so you can confirm it against your original.

Yes. The markup uses standard commands, so it renders correctly in MathJax and KaTeX as well as in a full LaTeX compiler. If you need MathML instead, you can convert the LaTeX with your usual toolchain.

The premium engine reads many handwritten equations in addition to printed ones. Handwriting is harder than print, so review the side-by-side result and fix any flagged symbols before you rely on it.

Your uploads are processed only to produce the LaTeX and are deleted automatically afterward. We never sell or share your documents.

You can try it with no signup, and a free account includes a monthly page bucket. The math engine is part of the premium AI tier; paid plans from $5/mo add more pages, batch processing, and API access.
