WHY MATHPASTER?

CHECK THE EQUATION BEFORE YOU SEND

Nested fractions, roots and matrices are easier to check when you can see their structure as you type.

MathPaster turns your visual equation into standard LaTeX. It helps you communicate the intended notation; it does not guarantee a correct answer from an AI.

LIVE WYSIWYG PREVIEW

Stop guessing if you missed a parenthesis or a curly brace. MathPaster provides a beautiful, real-time render of your equation as you write it, letting you catch syntax errors instantly.

SEAMLESS WORKFLOW

No external tabs. No awkward copy-pasting. Just pure convenience directly where you are working.

  1. Place your cursor on any text input box
  2. Press Ctrl+M
  3. Write your math visually
  4. Press Ctrl+Enter to insert!

USER MANUAL & FEATURES

Global Toggle

Press Ctrl + M (or Cmd + M on macOS) to instantly summon or hide the MathPaster visual editor when focused on any input field on any website.

Fast Insertion

Press Ctrl + Enter (or click the Insert button) to automatically type the rendered LaTeX formula directly into the active chatbot textbox.

Quick Close

Press Esc or toggle Ctrl + M again to hide the editor window. Your draft math equation is automatically saved in local browser storage so you can resume work anytime.

Autocomplete Selection

When typing commands, use autocomplete list and press Enter to select and commit the formula block without needing to click or press tab beforehand.

Draggable Window

Click and hold the header bar of the MathPaster editor to drag the window anywhere on your screen. This ensures the editor never blocks your active chat or reference documents.

Smart Caching

Your equation drafts are cached locally in real-time. If you close the popup, reload the page, or toggle the editor, your formula stays safely saved until you resume.

Backslash Autocomplete Recommendations

Type a backslash \ followed by your LaTeX symbol name (e.g. \frac, \sqrt, \alpha) to invoke autocomplete recommendations.

Use arrow keys or press Enter to select and insert the math node instantly. This allows superfast visual formula generation entirely via keyboard inputs.

TYPING IN EDITOR:
\int_a^b \frac{e^{-x^2}}{\sqrt{\pi}}
WYSIWYG LIVE RENDER:
∫ab (e-x² / √π) dx

Auto-Symbols Switch

Toggle the Auto-Symbols switch in the editor toolbar. When active, common combinations automatically format (e.g. typing / creates a fraction). Turn it off if you prefer to write traditional, raw LaTeX code.

Ready-to-insert LaTeX

Equations use inline LaTeX with single $ delimiters, ready to insert within your message.

Show LaTeX Code Bar

Toggle Show LaTeX Code Bar to show or hide the live preview bar at the bottom, which displays the exact LaTeX syntax that will be injected or copied.

Popup Size & Layout

Adjust sliders to resize the popup window (width, height), control the grid spacing gap, and scale symbol buttons. Make it compact or expand it to fit your desktop workspace.

Custom Theme & Accents

Choose your atmosphere: the warm simplicity of Paper, the focused detail of Precision, luminous Glass, or expressive Vaporwave. Each style brings its own surfaces, typography, and character.

Insert History FREE

A Win+V-style list of the last 20 expressions you inserted. Click the history icon in the editor header to reopen any of them and drop it straight back into the field — no retyping. Everything stays local in your browser.

Snippets PRO

Save whatever is in the editor as a reusable, named expression and organise your snippets into custom folders. Keep the formulas you use all the time one click away, on any site. Stored locally — no account needed.

Custom Symbol Tabs PRO

Build your own palette tabs from any \ LaTeX command, and edit, reorder, or hide the built-in tabs. Craft a workspace with exactly the symbols you reach for — nothing you don't.

QUESTIONS ABOUT MATHPASTER

What is MathPaster?

MathPaster is a Chrome extension with a visual math keyboard and equation editor. It converts the equations you build into LaTeX and inserts them into the active input field, including prompts in ChatGPT, Claude and Gemini.

How do I type math into an AI chatbot without writing LaTeX by hand?

Click the chatbot prompt, open MathPaster with Ctrl+M (Cmd+M on Mac), and build your equation visually. Use the symbol palette, type sqrt or int with Auto-Symbols enabled, or use backslash commands. Press Insert to place the generated LaTeX in the prompt, then send the prompt yourself.

Is MathPaster free?

The core equation editor, symbol palettes, Auto-Symbols, insert history, and Precision and Paper themes are free. Optional Pro adds saved snippets, custom symbol tabs, and Glass and Vaporwave themes. You can try five exercises on this website without installing the extension.

Does MathPaster solve equations or guarantee correct AI answers?

No. MathPaster is an input tool. Its visual preview helps you check the structure of a fraction, integral or matrix before inserting its LaTeX. Your chatbot provides the response, and mathematical answers still need checking.
