WHY MATHPASTER?

AI LIKES UNAMBIGUOUS MATH

Typing math conventionally like e^(-x^2) / (sqrt(pi)) is ambiguous and makes it difficult for AI models to understand your exact intent.

MathPaster generates flawless, standard LaTeX (e.g. \frac{e^{-x^2}}{\sqrt{\pi}}), ensuring ChatGPT, Gemini and Claude process your complex formulas with 100% accuracy.

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.

Inline vs Block Modes

Toggle the Inline/Block switch to change how MathPaster wraps your formula. Inline wraps formulas with single $ tags (perfect for standard sentences). Block mode uses double $$ tags (for centered, prominent equations).

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

Change the editor's design styling dynamically. Adjust sliders for Theme Accent Hue, Saturation, Lightness, and background tones to match your preferred theme, dark mode, or chatbot branding.

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.

HOW TO WRITE MATH TO AI: FAQ & GUIDE

Find answers to common questions about typing, inputting, and formatting math equations for AI chatbots like ChatGPT, Claude, and Gemini.

Why is it so hard to type math in AI chatbots?

Traditional text inputs (like the prompt boxes in ChatGPT, Claude, or Gemini) are built for standard text, not complex mathematical notation. Typing math equations using standard keyboard characters (for example, typing e^(-x^2) / sqrt(pi)) is extremely tedious, requires counting brackets, and is highly prone to syntax errors. Furthermore, raw text symbols are often ambiguous, leading the AI model to misinterpret your equation and output incorrect mathematical steps.

How to easily write and input math to ChatGPT, Claude, and Gemini?

The standard way to feed math to AI models is using LaTeX, which is the academic standard formatting they are trained to read. Since writing raw LaTeX commands like \frac{e^{-x^2}}{\sqrt{\pi}} by hand is difficult, the easiest solution is to use a visual WYSIWYG editor like MathPaster.

With MathPaster, you can either select symbols from a toolbar or use simple autocompleting math commands to build your equation visually. When finished, MathPaster automatically copies and inputs the properly formatted LaTeX directly into the active chatbot prompt box instantly, ensuring the AI understands your query without errors.

How do I input math to AI tools without syntax errors?

To ensure your mathematical equations are processed correctly by LLMs, follow these formatting guidelines:

  • Wrap in math delimiters: Use single dollar signs ($) for inline equations (e.g. $E=mc^2$) and double dollar signs ($$) for standalone, centered block equations.
  • Use a live visual preview: Never write complex formulas blind. Using an interactive preview tool lets you catch missing closing brackets or syntax errors in real-time.
  • Optimize your workflow: Install the MathPaster extension to press Ctrl+M on any input field, type your formula visually, and press Ctrl+Enter to type it into the chatbot box instantly.
Which browsers and AI models are supported by MathPaster?

Supported Browsers: MathPaster works in any Chromium-based desktop browser. This includes Google Chrome, Opera, Brave, Microsoft Edge, Vivaldi, and others.

Supported AI Models & Platforms: All leading Large Language Models (LLMs) and AI chatbots are fully trained to read, interpret, and solve mathematical formulas written in LaTeX. MathPaster works seamlessly with:

  • ChatGPT
  • Claude (Opus / Sonnet)
  • Gemini (Pro / Flash)
  • DeepSeek
  • Copilot
  • Qwen

You can use MathPaster to type math into any of these websites, as well as online homework tools, research wikis, and educational forums.
