## What it is
BlueSea is a browser extension for English learning that offers word selection translation, word highlighting, word danmaku (bullet comments), and spaced-repetition review based on the forgetting curve. It also tracks word frequency statistics and manages a local vocabulary notebook with import/export support.

## Use cases
- translate selected English words on any webpage
- build a personal vocabulary notebook while browsing
- review vocabulary with spaced repetition and forgetting curve scheduling
- highlight saved words across all web pages
- learn words passively via danmaku-style popups
- track word frequency statistics while reading English content

## When to choose
- you read English web content daily and want to passively build vocabulary
- you want an integrated translate-highlight-review workflow in the browser
- you prefer spaced-repetition scheduling embedded in your browsing experience

## When to avoid
- you need a full-featured standalone flashcard app like Anki
- you require sentence translation without configuring your own Youdao API keys
- you need an officially distributed extension from the Chrome Web Store (it must be loaded unpacked)
- you need guaranteed maintenance or support (no license, last release 2022)
