# Word Importance Evaluator

Drop-one embedding analysis using `sentence-transformers/static-retrieval-mrl-en-v1`.

Each word's importance score = the semantic distance introduced by omitting that word
from the prompt (higher = more critical to the meaning).

## Features

- **Importance bar chart** — horizontal bars coloured by a hot→cold colormap, with a draggable threshold line
- **Distribution per word** — violin-style sampled spread showing where each word's importance would land under paraphrase jitter
- **Threshold filter** — highlighted HTML output and summary of words above the cutoff
- **Multi-line prompt support** — all lines are concatenated into a single word list

## Usage

1. Paste a prompt (e.g. a Stable Diffusion caption)
2. Adjust the importance threshold (default 0.30)
3. Adjust distribution sample count if desired
4. Click **Analyse →**
