WordMark (Browser Extension)

Vocabulary lookup and highlighting extension for Chromium-based browsers.

What it does

• Lookup overlay for selected words, with pronunciation and optional translation.
• Popup word list with search/delete and highlight toggle.
• Shortcut support: assign a browser command (default suggested Alt+W) in your browser’s shortcut settings. Options page provides a direct “Go to shortcut settings” button.
• Optional translation when a provider API key is configured in Options.

Supported translation providers:

• Gemini
• DeepSeek
• Moonshot
• OpenAI
• Qwen
• Volcengine
• Zhipu

Install

• Chrome Web Store: WordMark

Getting started

1. Install dependencies: npm install
2. Build: npm run build (outputs to dist/)
3. Load unpacked extension from the dist/ folder in your browser.
4. After install, Options will open automatically. Click “Go to shortcut settings” to assign the command, then (optionally) configure translation.

Configuration

Translation is opt-in and disabled by default. To enable it:

1. Open Options and turn on “Enable translation (opt-in)”.
2. Select a provider.
3. Save the provider API key.
4. For providers that require it, also save the endpoint URL and model ID.

Notes:

• API keys are stored per provider. Clearing the key only affects the currently selected provider.
• Gemini endpoint/model overrides are optional; leave them empty to use the built-in endpoints and automatic model selection.
• DeepSeek, Moonshot, OpenAI, Qwen, Volcengine, and Zhipu require endpoint URL + model ID to be set.
