𧩠Step-by-Step: Build Your First Free AI App
Step 1: Create a Firebase Project

- Go to Build β Realtime Database β Create Database
Firebase gives you a free database for your app β perfect for storing user queries and AI responses.
Step 2: Connect Google Gemini API
- Go to https://aistudio.google.com
- Sign in with your Google account
- Click Get API Key under Gemini API
- Copy the key β youβll need it to connect AI to your app
Example backend (Node.js / JavaScript):
1 2 3 4 5 6 7 8 9 10 11 12 13 14 | import fetch from "node-fetch"; export async function getAIResponse(prompt) { const res = await fetch("https://generativelanguage.googleapis.com/v1beta/models/gemini-pro:generateContent?key=YOUR_API_KEY", { method: "POST", headers: { "Content-Type": "application/json" }, body: JSON.stringify({ contents: [{ parts: [{ text: prompt }] }] }), }); const data = await res.json(); return data.candidates[0].content.parts[0].text; } |
β Now your Firebase project can use Googleβs Gemini AI to answer prompts or generate smart content.
Step 3: Create a GitHub Repository
- Visit https://github.com β Log in
- Click New Repository β Name it
firebase-ai-app - Add your files (HTML, JS, CSS, and Firebase config)
- Click Commit β Push to GitHub
Your code is now saved online and can be shared or updated from anywhere.
Step 4: Connect GitHub with Firebase Hosting
Firebase allows you to deploy directly from GitHub:
- Go to Firebase β Hosting β Connect to GitHub
- Select your repository
- Choose your branch (usually
main) - Click Set up workflow
Now, whenever you update your project on GitHub, Firebase automatically rebuilds and deploys your app to the web.
Step 5: Make It SEO-Friendly
For your AI app to appear on Google Search, add these essentials in your HTML :
1 2 3 4 | <meta name="title" content="Build AI-Powered Apps for FREE - Firebase Studio & GitHub (2025)" /> <meta name="description" content="Learn how to build AI-powered web apps using Firebase Studio and GitHub for free.
