What is GenMB - AI App Generator
GenMB turns any idea, or any webpage, into a fully working app in seconds, generating production-ready React and full-stack applications directly from the browser. Describing what to build in the popup or side panel produces a complete app with UI, logic and routing, with quick-start templates like Landing Page, Dashboard, Portfolio or E-commerce for one-click starts. A design seen anywhere can be captured as a full page or a dragged region, and GenMB reads the screenshot to generate an app mirroring the layout, style and structure. An AI Tools tab runs on the current page with Summarize, Find Deals, Explain Code, Extract Design and Ask AI, while screenshots of pages and UI elements can be saved as reusable Clips that later seed new apps. The Apps tab lists recent projects with links to open, edit or deploy each one, apps deploy instantly at a genmb.com subdomain with TypeScript support and optional full-stack backends, and a keyboard shortcut opens the side panel from any tab. A free account with Google sign-in gets started with no credit card.

Generate production-ready apps from any webpage. Select text, capture screenshots, or clip designs for inspiration. GenMB – AI App Builder
Turn any idea — or any webpage — into a fully working app in seconds. GenMB lets you generate production-ready React and full-stack applications directly from your browser, without leaving the page you're on.
🚀 Generate apps from text
Open the extension popup or side panel, describe what you want to build, and GenMB generates a complete app with UI, logic, and routing — no boilerplate, no setup. Use quick-start templates like Landing Page, Dashboard, Portfolio, or E-commerce to get started in one click.
📸 Generate from any webpage
See a design you like? Capture the full page or drag to select any region, then describe what you want to build from it. GenMB reads your screenshot and generates an app that mirrors the layout, style, and structure — a powerful way to go from inspiration to working code instantly.
🛠 AI page tools
The AI Tools tab runs directly on whatever page you're viewing:
- Summarize — extract the key points from any article or doc
- Find Deals — surface discount codes and offers on product pages
- Explain Code — break down technical content in plain English
- Extract Design — pull colors, fonts, and layout info from any site
- Ask AI — type any question and get an answer based on the page content
📌 Clips
Save screenshots of pages and UI elements as reusable clips. Come back later and use any clip as the starting point for a new app — ideal for collecting inspiration as you browse.
📂 Your apps, always accessible
The Apps tab shows all your recent GenMB projects with a direct link to open, edit, or deploy each one — right from the side panel.
⌨️ Keyboard shortcut
Press ⌘⇧G (Mac) or Ctrl+Shift+G (Windows) to open the side panel from any tab, without touching the mouse.
What gets built
Apps are generated on GenMB and deployed instantly at a *.genmb.com subdomain. Every app includes production-quality code — React or Vanilla JS, with TypeScript support, component structure, and optional full-stack backends.
Requirements
A free GenMB account is required. Sign in with Google at genmb.com — no credit card needed to get started.
