What this extension does

MathVoice for VS Code is a VS Code extension that adds a sidebar panel and commands. From the panel you can:

Speak equations — dictate LaTeX using your microphone
Type equations — full LaTeX editing with the MathVoice Studio
Insert at cursor — edited LaTeX is inserted at the cursor in your active editor
Edit selected equations — select LaTeX in your file and load it for re-editing (Ctrl+Alt+M / Cmd+Alt+M)

How it works

Install from the VS Code Marketplace
Open a .tex, .md, or any text file
Press Ctrl+Alt+M (or Command Palette → “MathVoice: Open Studio”)
Speak or type your equation
Click Apply to insert LaTeX at the cursor

Data and permissions — full transparency

Permission	Scope	Purpose
Editor read/write	Active editor only	Uses the VS Code Extension API to insert LaTeX at the cursor and read selected text for re-editing. Only accesses the file you have open and only when you trigger a command.
Webview panel	VS Code sidebar	Opens a webview that loads MathVoice Studio from mathvoice.app. The webview is sandboxed by VS Code.
Configuration: `mathvoice.studioUrl`	User setting	Stores the Studio URL (defaults to mathvoice.app). Can be overridden for self-hosted deployments. No other settings are stored.
Microphone (browser/Electron)	Webview panel	Used by Studio for speech recognition. VS Code runs on Electron, so the browser speech engine handles audio. Audio never goes to MathVoice servers.
Network to mathvoice.app	Studio + intent API	Loads Studio in the webview and sends LaTeX to the intent API for processing. Formula data is not stored beyond the request.

No file contents are sent to our servers unless you explicitly load an equation into the editor and trigger an API call. The extension reads your files only to insert or read equations at your direction. See our Privacy Policy for full details.
