# Text Summarizer Web App

A text summarization web application built with FastAPI, Transformers, and a fine-tuned T5 model. The app provides a simple browser interface where users can paste text and get a concise summary.

This project is configured for deployment on Hugging Face Spaces using Docker.

## Live Demo

- Space page: `https://huggingface.co/spaces/Arpit16112/Text_Summarizer_FastAPI`
- Public app URL: `https://arpit16112-text-summarizer-fastapi.hf.space`

## Features

- Summarizes long text into a shorter version using a fine-tuned T5 model
- Simple web interface built with HTML, CSS, and JavaScript
- FastAPI backend with a JSON API endpoint
- Ready for Hugging Face Spaces deployment
- Can also be run locally with `uvicorn`

```

## Tech Stack

- FastAPI
- Uvicorn
- Hugging Face Transformers
- PyTorch
- Jinja2

## How It Works

1. The user enters text in the web interface.
2. The frontend sends the text to the `/summarize` API endpoint.
3. The backend cleans the input text.
4. The fine-tuned T5 model generates a summary.
5. The summary is returned and displayed in the browser.

## API Endpoint

### `POST /summarize`

Request body:

```json
{
  "dialogue": "Enter the text you want to summarize here."
}
```

Response:

```json
{
  "summary": "Generated summary text."
}
```

## Run Locally

### 1. Clone the repository

```bash
git clone <your-repository-url>
cd "Text Summarizer Web App"
```

### 2. Install dependencies

```bash
pip install -r requirements.txt
```

### 3. Make sure the model folder exists

The app loads the model from:

```text
saved_summary_model/
```

This folder must contain the fine-tuned model and tokenizer files.

### 4. Start the app

```bash
uvicorn app:app --reload
```

### 5. Open in browser

```text
http://127.0.0.1:8000
```

## Deploy on Hugging Face Spaces

This project uses a Docker-based Hugging Face Space.

### Required files for deployment

- `app.py`
- `index.html`
- `requirements.txt`
- `Dockerfile`
- `README.md`
- `saved_summary_model/`

### Deployment steps

1. Create a new Space on Hugging Face.
2. Choose `Docker` as the Space SDK.
3. Upload or push the project files to the Space repository.
4. Wait for Hugging Face to build the Docker image.
5. Open the deployed Space once the build completes.

## Docker Notes

The app runs on port `7860` inside the container, which matches Hugging Face Spaces requirements.

The Docker container starts the app with:

```bash
uvicorn app:app --host 0.0.0.0 --port 7860
```

## Notes

- `render.yaml` is not needed for Hugging Face deployment.
- `__pycache__/` is not needed for deployment.
- If you move CSS or JavaScript into separate files, make sure they are properly linked from `index.html`.

## Future Improvements

- Add input validation and better error messages
- Add loading indicators and improved UI feedback
- Move inline CSS and JavaScript into separate static files
- Add example input text
- Add automated tests
