WriteTex for Obsidian - Usage Guide

This plugin allows you to use the WriteTex app with Obsidian. WriteTex is an AI-powered OCR app (available on iOS Android Windows Mac) that converts images of math and diagrams into LaTeX, TikZ, or Markdown. This plugin acts as a bridge, enabling the WriteTex app to insert the recognized code directly into your Obsidian notes. 中文

Features

  • Companion for WriteTex App: Seamlessly connects the WriteTex mobile app to your desktop Obsidian editor.
  • Local Proxy Server: Runs a lightweight server inside Obsidian (Port 50905) to receive data from the app.
  • Context Awareness: Automatically sends the text surrounding your cursor to the AI, improving accuracy by understanding your current document's style and variables.
  • Automatic Discovery: Uses mDNS (Bonjour) so the WriteTex iOS app can find your computer automatically.
  • Direct Insertion: Generated code is inserted immediately at your cursor.
  • Streaming: Watch the text appear in real-time.

Installation

  1. Download the latest release.
  2. Put main.js and manifest.json in <VAULT>/.obsidian/plugins/writetex-obsidian
  3. Open Obsidian Settings > Community Plugins and enable WriteTex for Obsidian.

Configuration

  1. Go to Settings > WriteTex.
  2. API Endpoint: Default is https://api.openai.com/v1. Change this if you use a compatible provider (e.g., OpenRouter, LocalAI).
  3. API Key: Enter your OpenAI API key (sk-...).
  4. Model: Default is gpt-4o. You can change this to gpt-4-turbo or other vision-capable models.
  5. Custom Prompt: (Optional) Add specific instructions, e.g., "Always use \bm for bold math symbols."

Usage

  1. Start the Server:

    • The server starts automatically when Obsidian loads.
    • Check the status bar in the bottom right: it should say "WriteTex: On".
    • If it says "Off", open the Command Palette (Cmd/Ctrl + P) and run "WriteTex: Start Server".

  2. Connect Client (e.g., iOS App):

    • Open the WriteTex app on your phone.
    • Ensure your phone and computer are on the same Wi-Fi network.
    • The app should automatically discover "WriteTex Obsidian @ [YourHostname]".
    • If automatic discovery fails, manually enter your computer's IP address and port 50905.

  3. Scan and Insert:

    • Place your cursor in an Obsidian note where you want the code to appear.
    • Take a picture of a math formula or diagram using the mobile app.
    • The plugin will receive the image, analyze it with the context of your current note, and stream the LaTeX/Markdown result directly into your editor.

Troubleshooting

  • Server won't start: Check if port 50905 is being used by another application.
  • Mobile app can't connect:
    • Ensure both devices are on the same Wi-Fi.
    • Check your computer's firewall settings to allow incoming connections on port 50905.
  • "Unauthorized" error: Ensure the client app sends the Authorization header Bearer writetex.
