Create Your First App

Follow these simple steps to go from idea to working app. No coding experience required. GenMB transforms your plain English descriptions into fully functional web applications.

5 Steps to Your First App

Go from idea to a live, deployed web application in minutes. Each step builds on the previous one — most people have their first app running within five minutes.

Click “Get Started” and sign in with your Google account. Authentication is quick and secure — no credit card required for the free tier. Your account gives you access to app generation, version history, subdomain deployment, and all core GenMB features. Your projects are automatically saved and accessible from any device.

Describe Your App

Tell GenMB what you want to build in plain English. Be specific about features, design preferences, and functionality. For example: “Create a personal budget tracker with expense categories, a pie chart showing spending breakdown, and the ability to set monthly limits.” The more detail you provide, the better the results. You can always refine through chat afterward.

Watch It Generate

GenMB's AI analyzes your request, understands the requirements, and generates production-ready code in real-time. You'll see the code appear as it's written — HTML structure, CSS styling with Tailwind, and JavaScript logic.

Preview and Refine

See your app in the live preview panel as code generates. Interact with it just like a real user would. Use the chat to request changes — adjust colors, add features, fix issues, or restructure layouts. Each change creates a version snapshot you can rollback to if needed. The iterative process lets you refine until your app is exactly what you envisioned.

Deploy

Click “Deploy” to publish your app to a custom subdomain (yourapp.genmb.com) with SSL/HTTPS included automatically. Deployment is instant — your URL is live and shareable within seconds. Update your app anytime with one click to push new changes. No server configuration, no DNS setup, no hosting fees.

Agent Mode for Complex Apps

For complex multi-feature applications, enable Agent Mode to let AI break down your request into steps and build autonomously with automatic error recovery. Agent Mode works through multiple iterations, planning the architecture and implementing each piece systematically.

Choose Your Framework

GenMB supports four frameworks. Pick the one that fits your project — you can always start a new app with a different framework later.

Vanilla JS

Best for simple apps, calculators, landing pages, and single-purpose tools. Generates the fastest load times and smallest bundle size because there is no framework overhead. Perfect for beginners who want clean, readable code without the complexity of component systems. Use this when you need maximum performance or want to learn web fundamentals.

React

Best for complex applications with sophisticated state management, interactive dashboards, and multi-component architectures. React's component model makes it easier to build and maintain large apps with reusable pieces. Choose React when you have multiple screens, complex user interactions, or plan to extend the app significantly after generation.

React + TypeScript

Best for large, production-grade applications where type safety matters. TypeScript provides better IDE support, catches errors at compile time, and makes refactoring easier. Ideal for complex multi-page apps, SaaS dashboards, and projects you plan to maintain long-term.

React Native

Best for cross-platform mobile apps. Uses React Native components (View, Text, FlatList) with Expo and renders via react-native-web for preview. Choose React Native when you want to build native mobile experiences with navigation, gestures, and device APIs.

Not sure which to pick?

Start with Vanilla JS for your first app — it generates the fastest and produces the simplest code to understand. Move to React or React + TypeScript when you need component-based architecture or type safety for larger projects.

Tips for Better Prompts

The quality of your prompt directly shapes the quality of your app. The more specific you are, the better your results will be. Here are techniques that consistently lead to better generated apps.

Be specific about features: "Add a dark mode toggle in the header that persists user preference"
Mention design preferences: "Use a modern, minimalist design with blue accents, rounded corners, and subtle shadows"
Describe user interactions: "When the user clicks submit, validate the form, save the data, and show a success toast"
Include content details: "Add 3 pricing tiers: Free (5 projects), Pro at $10/month (unlimited), Enterprise at $50/month (team features)"
Specify framework if needed: "Build this with React for component reusability and state management"
Define data structures: "Each task has a title, description, due date, priority level, and completion status"
Describe empty states: "When there are no items, show a friendly message with an add button"

You do not need to get everything right in the first prompt. Start with the core idea and use the chat to iterate. Each refinement round adds or adjusts features while preserving what already works.

Example Prompts to Try

Get inspired by these detailed prompts. Copy and modify them for your own projects — they demonstrate the level of detail that produces great results.

Personal Finance Tracker

"Create a personal budget tracker where users can add income and expenses with categories (food, transport, entertainment, bills). Show a monthly summary with a pie chart of spending by category, a line chart of balance over time, and the ability to set monthly budget limits with progress bars."

Task Management App

"Build a Kanban board with three columns: To Do, In Progress, and Done. Users can add tasks with title, description, and due date. Tasks should be draggable between columns. Include a search bar to filter tasks and color-coding for overdue items."

Landing Page

"Create a SaaS landing page for a project management tool. Include a hero section with headline and CTA, features section with 6 cards and icons, pricing table with 3 tiers, testimonials carousel, FAQ accordion, and footer with newsletter signup. Use a professional blue/white color scheme."

Weather Dashboard

"Build a weather dashboard that shows current conditions (temperature, humidity, wind) with a large icon, 5-day forecast cards, and a search bar to look up cities. Use a gradient background that changes based on weather conditions (sunny yellow, cloudy gray, rainy blue)."

What to Expect

When you submit your first prompt, GenMB analyzes your description and generates code in real-time. For simple apps, generation completes in under a minute. Complex multi-feature applications with Agent Mode may take a few minutes as the AI works through multiple steps, but you can watch progress throughout.

The generated code follows industry best practices — clean HTML structure, Tailwind CSS for responsive styling, and well-organized JavaScript. React apps use proper component patterns with hooks and state management. The code is readable and maintainable, suitable for learning or extending.

Your first app might not be perfect, and that is expected. Use chat to iterate — request changes, add features, adjust styling. Each conversation turn refines the app further. Version history lets you experiment without fear of breaking things. The goal is not perfection on the first try but rapid iteration toward what you want.

Iterate with Confidence

Every change you make through chat creates a new version. If a refinement goes in the wrong direction, you can instantly rollback to any previous version from the version history panel.

After Your First App

Once you have created your first app, there is a lot more you can explore. Here is what to try next.

Deploy and Share — Publish your app to a custom subdomain and share the URL with others. Get feedback from real users to guide your next iteration.
Enable PWA — Turn your app into a Progressive Web App for offline access and mobile installation. Users can add it to their home screen.
Try Agent Mode — For your next complex project, enable Agent Mode to let AI plan and build autonomously with multiple steps and error recovery.
Export and Extend — Download your code as a ZIP file and continue development locally. Add backend integrations, connect APIs, or deploy elsewhere.
Import from Figma — Have a Figma design? Import it directly and GenMB generates code matching your mockup with extracted design tokens.
Set Up Agents — Build AI agents, visual workflows, and scheduled jobs. Connect HTTP, email, AI, and conditional nodes without writing code.
Track Your Users — Enable built-in analytics to monitor visitors, referral sources, and top pages for your deployed apps.

FAQs

Do I need coding experience to use GenMB?▾

No coding experience is required. GenMB is designed for everyone — from complete beginners to experienced developers. You describe what you want in plain English, and the AI generates all the code. If you do know how to code, you can edit the generated code directly or export it to continue development in your preferred environment.

What happens if the generated app is not quite right?▾

Use the chat to request specific changes. Be precise about what you want different: "Change the header color to dark blue" or "Add a logout button in the top right corner." Each change creates a version you can rollback to if needed. The iterative refinement process is key to getting exactly what you want.

How complex of an app can I build?▾

GenMB can build anything from simple calculators to complex multi-screen applications with dashboards, forms, charts, and interactive features. For complex apps, use Agent Mode which breaks your request into steps and builds autonomously. The practical limit depends on how well you can describe your requirements.

Can I use the code outside of GenMB?▾

Yes! You own 100% of the generated code. Export your app as a ZIP file and deploy it anywhere — your own server, Vercel, Netlify, or any hosting provider. The code uses standard web technologies (HTML, CSS, JavaScript, React, or TypeScript) with no proprietary dependencies.
