Why choose us?
Six reasons — hover or tap one to see it.
Start in seconds
Sign up and start typing. Typst documents compile to a live PDF in the browser — no TeX install, no template hunting, no local setup to break the night before a deadline.
Math Drive, live collaboration, and version history come with every plan. Free includes 3 Typst and 3 LaTeX documents — see the plans.
One keyboard, six modes
The same mint STEM keyboard inside the editor — one mode for every subject.
Pure Math
Number sets, logic, operators — proofs and analysis at hand.
Statistics
Distributions, hypothesis tests, and combinatorics.
Physics
Vectors, nabla, Dirac notation, and constants like ℏ.
Chemistry
Draw structures, then copy as an image or chemfig / mhchem LaTeX.
Graphing
Cartesian, polar, and 3D plots — pan, zoom, export image or TikZ.
MATH Keys
Writing STEM elsewhere?
MATH Keys is the free Chrome extension with the same STEM keyboard. Copy as an image or LaTeX into Docs, Slides, Word, PowerPoint, Keynote, and Gmail.

Yes. MATH Keys is an online LaTeX editor with a STEM keyboard, a live PDF from a real pdflatex compile, and AI Fix for the log. Free includes 3 editable LaTeX documents; Plus and Pro make them unlimited. Details are at https://www.mathkeyboards.com/latex/.
Yes. MATH Keys is a free online Typst editor — up to 3 documents on Free, unlimited on Plus — with the same STEM keyboard and a live PDF. Typst→LaTeX conversion is on Plus and Pro. Details are at https://www.mathkeyboards.com/typst/.
Yes. The cloud editor includes a Free plan with 3 Typst and 3 LaTeX documents and limited AI Fix. Plus and Pro unlock unlimited documents, Typst→LaTeX conversion, higher limits, and more collaboration. The Chrome extension is also free forever for pasting into Docs and Slides.
No. Start free with Typst or LaTeX and the mint STEM keyboard — build formulas visually and insert them into your document. You can learn syntax gradually instead of fighting package installs on day one.
Typst is a modern typesetting language — clearer syntax than classic TeX for many STEM documents, with fast preview. MATH Keys includes Typst and LaTeX on Free: you can write full documents and see a live PDF without becoming a TeX expert first. Upgrade when you need unlimited documents.
Yes. MATH Keys is a cloud editor with a live PDF, Math Drive, and collaboration. Start with 3 Typst and 3 LaTeX documents on Free; Plus and Pro unlock unlimited documents when a journal or lab template needs more. You don’t install a local TeX distribution — compiling happens in the editor.
Yes — via the free Chrome extension. Write an equation on the same mint STEM keyboard, then copy as an image or LaTeX and paste into Google Docs or Slides. It also works in Word, PowerPoint, Keynote, and Gmail. Your MATH Keys account works with both the editor and the extension.
MATH Keys includes a chemistry mode and structure canvas: draw molecules, then export as an image or chemfig/mhchem. Use it in the cloud editor or the Chrome extension for lab write-ups and slides — not only pure math.
