AI-powered summarization for articles, PDFs, and Word documents.

Ai Summarizer turns long-form content into clean summaries, key points, quick metrics, translation output, and audio-ready text in one focused workflow.

Ai Summarizer is a full-stack web application designed to simplify content digestion. It supports both public article URLs and uploaded documents, then produces a structured output that is easier to read, translate, and reuse.

The experience is built around a simple flow:

1. choose a source
2. generate a summary
3. review the key points and metrics
4. translate or listen to the result

When a valid GEMINI_API_KEY is available, the app uses Gemini for higher-quality summarization. If Gemini is unavailable, the backend falls back to a local summarization strategy so the product remains usable.

• React
• TypeScript
• Vite
• Express
• TanStack Query
• Tailwind CSS
• Gemini API
• Vercel serverless API handlers

npm install

cp .env.example .env

Update .env with your values:

GEMINI_API_KEY=your_real_gemini_api_key
NODE_ENV=development
PORT=5001
GEMINI_MODEL=gemini-1.5-flash
MAX_CONTENT_LENGTH=30000

npm run dev

Open:

http://127.0.0.1:5001

Run the checks and production build:

npm run check
npm run build

Start the built server locally:

npm start

This project is already configured for Vercel.

1. Push the project to your GitHub repository.
2. Import the repository into Vercel.
3. Use these project settings if Vercel asks:

Build Command: npm run build
Output Directory: dist/public
Install Command: npm install

4. Add these environment variables in the Vercel dashboard:

GEMINI_API_KEY
GEMINI_MODEL
MAX_CONTENT_LENGTH

npm i -g vercel
vercel

Then add the same environment variables in Vercel.

• Do not push .env to GitHub.
• Some websites may restrict scraping or return partial content.
• If GEMINI_API_KEY is invalid, the app falls back to a local summarizer.
