# 🤖 NLP Assistant

A lightweight NLP-powered assistant that provides **summarization**, **news classification**, and **event detection** from text, PDF uploads, or article URLs. Built using `Transformers`, `KeyBERT`, `Streamlit`, and `pdfplumber`.

---

## 🚀 Features

- 📄 **Summarization** (with sliding window + meta-summary)
- 🗞️ **News Classification** using `DistilBERT`
- 📌 **Event Detection** with `KeyBERT`, `spaCy` & `TF-IDF`
- 📥 Upload **PDFs**
- 🔗 Input article **URLs** using `newspaper3k`

---

## 🛠️ Tech Stack

- `Streamlit` - Web UI
- `Transformers` (HuggingFace)
- `KeyBERT`
- `pdfplumber` for PDF extraction
- `PyTorch` (auto GPU/CPU)
- `scikit-learn` & `sentence-transformers` for KeyBERT
- `newspaper3k` for url support
