# ✂️ Snippet Generator

Recreates Google Vertex AI / Gemini grounding-style extractive snippets.

## How it works

1. **Sentence Segmentation** - Splits document on sentence boundaries and newlines, filters noise (URLs, questions, low-alpha content)
2. **Cross-Encoder Scoring** - Uses `cross-encoder/ms-marco-electra-base` to score query-sentence relevance
3. **Budget Selection** - Picks top-scoring sentences within character/count limits
4. **Document-Order Stitching** - Reassembles in original order with `...` for gaps

## Model

Uses [MS MARCO Cross-Encoder](https://huggingface.co/cross-encoder/ms-marco-electra-base) trained on search relevance data - the same task as snippet generation.

## Usage

1. Enter a search query
2. Paste document content
3. Adjust settings (max chars, max sentences)
4. Click "Generate Snippet"

## Example

**Query:** `best prostate cancer treatment in the world`

**Output:**
```
This makes Asklepios one of the best prostate cancer treatment centers for foreigners. ... Spain is a leader in prostate cancer treatment, with top clinics like Centro Médico Teknon, Quironsalud Madrid, and Hospital Quiron Barcelona. ...
