What is an online math keyboard?
An online math keyboard gives you the keys a normal keyboard is missing: ∞, √, ∑, ∫, π, ≤, ≠, ∈, Greek letters, arrows and structures such as fractions and exponents. Tap them on a phone or click them on a computer, and the equation is laid out as you go. When you are done, copy it as plain Unicode text for chat and email (x² + y² ≤ r²), as LaTeX, as an image, or as an editable Word equation.
How to type math symbols
- Click the equation box. The math keyboard opens with numbers, operators, Greek letters and symbol pages; on a phone it replaces the normal keyboard.
- Tap keys to build the equation, or click symbols in the palette below. Search the palette by name, for example "infinity" or "not equal".
- Choose Copy text to copy plain Unicode symbols that paste into any app, even ones without math support.
- For documents, choose Copy for Word, Copy image or Copy LaTeX instead.
Why use this math keyboard
- Real math, not just symbolsMost symbol pickers stop at single characters. This keyboard also builds fractions, roots, sums, integrals and matrices.
- Copy as plain textUnicode output uses superscripts, subscripts and math symbols that paste into WhatsApp, Slack, Discord, email and social posts.
- Made for touchThe on-screen keyboard has large keys and replaces the phone keyboard while you type math, so you are not hunting for symbols.
- Copy it anywherePaste an editable equation into Word, an image into Google Docs or Slides, $…$ into Markdown and Notion, MathML into web pages, or plain Unicode text into email and chat.
- Private by designEquations are rendered by your own browser. Nothing you type is sent to a server, so unpublished research, exam questions and homework stay on your device.
- Free, no accountEvery feature works without signing up, without a watermark and without a daily limit. Recent equations are kept in this browser, not in a cloud account.
Who uses an online math keyboard
- Students on phones and Chromebooks. Type answers and questions with symbols that are not on the keyboard.
- Messages and forums. Copy equations as plain Unicode text (x² + y² = r²) for email, Slack, Discord or a forum that has no math support.
- Tutors. Send clear formulas in chat and video-call messages.
- Worksheets and slides. Build equations for tests, worksheets and lecture slides, then paste them into Word, Google Docs or PowerPoint.
- Social posts. Add π, ∞, ≠ or x² to a caption or comment.
- Web pages and docs. Get $…$ for Markdown, Notion, Obsidian and GitHub, MathML for HTML, or an SVG with alt text for a blog post.
How to insert equations into Word, Google Docs, Canvas and more
- Microsoft Word
- Copy for Word, then paste. Word converts it to a native, editable equation. If you see code, choose Keep Text Only in the paste options.
- Google Docs and Slides
- Copy image (or download a PNG at 2× or 4×) and paste. Docs and Slides do not accept MathML or LaTeX.
- PowerPoint and Keynote
- Download an SVG for a sharp, scalable equation, or a transparent PNG.
- Canvas, Moodle and Blackboard
- Copy LaTeX and paste it into the LMS equation editor’s LaTeX or advanced mode, or insert a PNG with its alt text.
- Notion, Obsidian and GitHub
- Copy $…$ for inline math or $$…$$ for a display block. All three render LaTeX with KaTeX or MathJax.
- Overleaf and LaTeX documents
- Copy \[…\] or the equation environment and paste it into your .tex file.
- Email, Slack, Discord and forums
- Copy Unicode text for symbols that paste anywhere, or Copy image when the layout matters.
- Web pages and blogs
- Copy MathML for native browser rendering, or HTML <img> for an SVG image with alt text built in.

Typing shortcuts and LaTeX cheat sheet
Type the shortcut in the visual editor, or the LaTeX in the LaTeX box. The symbol palette in the editor lists 200+ more symbols with their LaTeX commands.

Writing documents with math
For whole documents, write in the Markdown editor with $…$ math and export with Markdown to PDF or Markdown to DOCX. To pull equations out of a PDF as text, try PDF to Markdown. For quick sums, use the percentage calculator.
Example: a limit definition as plain text
Tap ∀, ε, > and 0 and keep going until you have the ε-δ definition of a limit. Choose Copy text and paste it into a message: ∀ε > 0 ∃δ > 0: |x−a| < δ ⇒ |f(x)−L| < ε. No LaTeX and no image needed.
What to expect from the result
Plain text cannot show every layout. Fractions become a/b, roots become √(…), and complex exponents keep a ^ sign. Some fonts lack rare superscript letters. When the layout matters, use Copy image or Copy for Word instead.
Online Math Keyboard questions
How do I type math symbols on a keyboard?
Click the equation box and use the on-screen math keyboard, or type names like pi, sqrt, infinity or sum; they turn into symbols automatically. Then use Copy text to paste the symbols anywhere.
Can I copy and paste math symbols?
Yes. Copy text gives plain Unicode characters (√, ∑, ≤, ², ₁ and so on) that paste into any app. You can also click a symbol in the palette to insert it.
Does it work on iPhone and Android?
Yes. On a phone the math keyboard replaces the normal keyboard while the equation box is focused, with pages for numbers, symbols, Greek letters and functions.
How do I put an equation into Microsoft Word?
Choose Copy for Word, click in your document and paste with Ctrl+V (Cmd+V on a Mac). Word turns the copied MathML into a native equation you can edit with Word’s own equation tools. If you see code instead, open the paste options and choose Keep Text Only.
Are my equations sent to a server?
No. The editor, the LaTeX renderer and every export run in your browser. There is no account and nothing you type is stored anywhere except your own browser’s recent-equations list, which you can clear.
