The Lumenfall AI Image Studio Chrome extension brings image generation and editing into a browser side panel. Access all Lumenfall models without leaving the page you’re on.

​
What it does

  • Generate images from text prompts using any model in the Lumenfall catalog.
  • Edit images by right-clicking any image on the web and choosing “Edit with Lumenfall”, or by dragging images into the side panel.
  • Brainstorm illustrations — extract text from the current page and generate contextual images.
  • Gallery — all generated images are saved locally for later download, copy, or re-editing.
The extension communicates only with the Lumenfall API. No analytics, tracking, or third-party services are involved. See our Privacy Policy for details on how the API handles your data.

​
Installation

Install the extension from the Chrome Web Store. Once installed, click the Lumenfall icon in the toolbar or press Ctrl+Shift+L (Mac: Cmd+Shift+L) to open the side panel.

​
Setup

  1. Create a free account at lumenfall.ai.
  2. Generate an API key from your dashboard.
  3. Open the extension and paste the key in Settings.
Models load automatically once a valid key is set. Your API key is stored locally on your device and is never synced or transmitted anywhere other than the Lumenfall API.

​
Permissions

The extension requests minimal permissions at install time. Broad host access (https://*/*) is not requested upfront — instead, Chrome prompts you the first time the extension needs to fetch an image from a specific site (e.g. when you right-click “Edit with Lumenfall” or drag an image in). You can revoke these per-site permissions at any time in chrome://extensions.

Build your own

The extension is open source and designed to be a starting point for building your own Lumenfall-powered tools.

GitHub Repository

Clone the repo, swap in your own UI, and ship a custom Chrome extension backed by the Lumenfall API.
 The project is vanilla HTML/CSS/JS with no build dependencies for development. Load it as an unpacked extension in Chrome and start hacking: 
git clone https://github.com/lumenfall-ai/lumenfall-chrome-extension.git
cd lumenfall-chrome-extension
  1. Open chrome://extensions and enable Developer mode.
  2. Click Load unpacked and select the repo directory.
  3. Open the side panel and add your API key.
For production builds (Web Store submission): 
bun run scripts/build.ts        # → dist/ + lumenfall-chrome.zip
bun run scripts/build.ts --dev  # → dist/ with localhost enabled
