NuModeX Ext Maker SoraVantia מאת

Build browser extensions and websites with AI. Just describe what you want.

NuModeX Ext Maker is a free, open-source AI builder that turns plain-language descriptions into complete, ready-to-use Manifest V3 browser extensions and static websites. No coding required to get started. Describe what you want in a chat, and NuModeX generates every file you need (HTML, CSS, JavaScript, manifest.json, and more), then packages it as a downloadable ZIP. Build a browser extension or a full static website with the same AI workflow.

WHY NUMODEX EXT MAKER
- Two builders in one: generate browser extensions AND static websites or landing pages from a prompt
- Free and open source. Inspect the code and verify exactly what runs in your browser (github.com/SoraVantia/NuModeX-Ext-Maker)
- Privacy-first. No backend, no analytics, no telemetry, no tracking, no account. Everything runs and stays in your browser.
- Your key, your control. Bring your own API key for Google Gemini, OpenAI, or Anthropic Claude models. It is stored locally and never sent to us or anyone else, and you pay your AI provider directly.
- Try it with no API key. Use on-device, browser-provided AI, or connect any local or remote AI server.
- Build for 6 browsers, in 9 languages.

HOW IT WORKS
1. (Optional) Add your API key for Google Gemini, OpenAI, or Anthropic Claude models, or pick an on-device model and skip this step
2. Describe the extension or website you want
3. Click Build Extension or Build Website
4. Preview it live, refine with AI, then download the ZIP

WHAT YOU CAN DO
- Generate full Manifest V3 browser extensions from a prompt
- Generate static websites and landing pages (HTML/CSS/JS) from a prompt
- Use cloud AI, on-device AI, or any custom or local model (multi-provider support)
- Chat conversationally with full history, and send text and image prompts
- Edit a single file or improve the whole project with AI
- Hand-edit code in the built-in inline editor
- Review changes with unified or side-by-side diff, with undo for AI edits
- Live preview in a sandboxed iframe
- One-click ZIP download, multiple projects, automatic saving, and auto-naming from the manifest
- Import and continue projects from exported JSON
- Dark mode with system detection, keyboard shortcuts, and a built-in help guide

OPEN SOURCE AND PRIVATE BY DESIGN
NuModeX Ext Maker has no backend server. Your prompts, API keys, and generated code never touch our servers, because there is no server to send them to. The source is open, so you can verify exactly what runs in your browser.

KEYBOARD SHORTCUTS
Enter: Send message. Shift+Enter: New line. Ctrl/Cmd+Enter: Build Extension. Ctrl/Cmd+Shift+Enter: Build Website.

TIPS FOR BEST RESULTS
Start simple and build up. Use Edit and Improve to add features after the first generation. Import existing projects to keep working on them. Use a larger-context model for complex builds. If a generation fails, simplify the prompt or try a different model.
