## What it is
A Chrome extension that lets users search a webpage using natural language questions instead of exact string matching. It runs a MobileBERT question-answering model fine-tuned on SQuAD via TensorFlowJS and highlights relevant elements on the page.

## Use cases
- search a webpage with a natural language question
- find information on a page without exact string match
- semantic in-page search in the browser
- ask questions about page content like Ctrl-F but smarter
- highlight answers to a question on a webpage

## When to choose
- you want to find answers on a page phrased differently from the text
- you prefer a browser extension over installing separate tools
- you want fully client-side BERT inference via TensorFlowJS

## When to avoid
- you need exact string matching or regex search
- you need fast, low-latency search on very large pages
- you need a production-grade, actively maintained tool - it is an experiment last released in 2020

## Facets
- artifact type: plugin
- maturity: experimental
- function: search-engine, nlp, machine-learning
- domain: browser-extensions
