MathVoice for Obsidian

A community plugin that lets you create and edit math equations in Obsidian by voice, directly in any markdown note.

What this extension does

MathVoice for Obsidian is a community plugin that adds a ribbon icon and side panel to Obsidian. From the side panel you can:

Speak equations — dictate LaTeX using your microphone
Type equations — full LaTeX editing with live preview
Insert into notes — equations are inserted at the cursor wrapped in $$...$$ (block) or $...$ (inline)
Edit existing equations — select LaTeX in your note and load it into the editor

How it works

Install via Obsidian Community Plugins (or manual install)
Click the MathVoice ribbon icon to open the side panel
Speak or type your equation
Click Apply to insert LaTeX at the cursor in your active note

Data and permissions — full transparency

Permission	Scope	Purpose
Read and modify active note	Current note only	Uses the Obsidian Plugin API to insert LaTeX at the cursor position and read selected text for re-editing. Only touches the note you have open and only when you trigger an action.
Add ribbon icon & side panel	Obsidian UI	Registers a ribbon icon and side panel view for accessing MathVoice Studio.
Network to mathvoice.app	Embedded iframe + API	The side panel loads Studio from mathvoice.app. LaTeX strings are sent to the intent API for processing. Formula data is not stored beyond the request.
Microphone (browser/Electron)	Side panel	Used by Studio for speech recognition. Obsidian runs on Electron, so the browser’s speech engine handles audio. Audio never goes to MathVoice servers.

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

Requirements

Obsidian 1.4.0 or later (desktop or mobile)
