# Accessibility PowerPoint Analyzer (Backend)
This is the backend for the Accessibility PowerPoint Analyzer, built with FastAPI. It processes `.pptx` files to identify and remediate accessibility issues, including generating AI alt-text for images using local vision models.
## 🌟 Features
- **FastAPI Backend:** Handles file uploads and processing asynchronously.
- **Local AI Vision:** Uses BLIP/GIT models via `transformers` to generate alt-text for free.
- **CORS Enabled:** Configured to communicate with the Vercel frontend.
- **Automatic Remediation:** Fixes color contrast and missing titles.
## 🛠 Tech Stack
- **Language:** Python 3.10+
- **Framework:** FastAPI
- **Libraries:** `python-pptx`, `torch`, `transformers`, `lxml`
- **Deployment:** Docker on Hugging Face Spaces
## 🚀 How to use
The frontend (deployed on Vercel) sends requests to this Space's endpoint.
For local testing:
1. Install dependencies: `pip install -r requirements.txt`
2. Run the server: `python app.py`
