Mouse Sprite
— AI Learning Companion

Mouse Sprite
—— AI 学习精灵

Install安装 Chrome Web Store ↗
01 · Overview01 · 概述 Why为什么

A published Chrome extension — a learning sprite that floats on any page. Drag-select any term and it explains it in context; pause too long and it offers a hand. Every lookup is saved locally and resurfaced for spaced review.

一个已上架的 Chrome 扩展 —— 在任意网页悬浮一只学习精灵。拖拽选中任意词，它就结合上下文解释；停顿太久，它会主动搭把手。每次查询都本地保存，并按间隔复习重新浮现。

Privacy-first by design: bring your own OpenAI-compatible API, and all data stays in chrome.storage — nothing is uploaded to a third party. Works on anything from Wikipedia to dense academic papers.

天生隐私优先：自带 OpenAI 兼容 API，所有数据都留在 chrome.storage，不上传任何第三方。从维基百科到艰深的学术论文，处处可用。

The sprite at work精灵实战

Mouse Sprite explaining a term in-page on Wikipedia
01Plate 01 In-page · Wikipedia
Fig. 01 On Wikipedia. Highlight any term and the sprite explains it in the page's own context — no tab-switching. 在维基百科上。选中任意词，精灵就结合页面上下文解释 —— 无需切换标签页。
Mouse Sprite riding along on an academic paper (CNKI)
02Plate 02 In-page · academic paper
Fig. 02 On an academic paper (CNKI). The same companion rides along on dense, specialist text — superconductor research here. 在学术论文上（知网）。同一个伴读精灵也能跟着啃专业长文 —— 这里是超导研究。
Spaced-review tab surfacing previously seen terms
03Plate 03 Review · spaced repetition
Fig. 03 Spaced review. Terms you've met resurface as review cards — “saw this recently, worth a quick recap.” 间隔复习。遇到过的词以复习卡重新浮现 —— “最近见过，值得快速回顾”。
History tab with timestamped local lookups
04Plate 04 History · saved locally
Fig. 04 History, kept locally. Every drag-to-explain lookup, timestamped — nothing leaves the browser. 本地保存的历史。每一次拖拽解释都带时间戳 —— 一切都不出浏览器。
Mouse Sprite settings — bring your own OpenAI-compatible LLM API
05Plate 05 Settings · bring your own LLM
Fig. 05 Settings — bring your own LLM. Any OpenAI-compatible endpoint (OpenAI, a router, even local Ollama); your key lives only in chrome.storage.sync, and a stall threshold triggers the “need a hand?” prompt. 设置 —— 自带大模型。任意 OpenAI 兼容端点（OpenAI、路由、甚至本地 Ollama）；密钥只存在 chrome.storage.sync，停顿阈值触发 “need a hand?” 提示。
