Non-native English speaker here. I built a tool to understand hard sentences in papers without leaving the page

I’m not a native English speaker and I read a lot of papers in English, so I often get stuck on one sentence or one figure and end up switching tabs to ChatGPT or a translator, then losing my place. So I made a small Chrome extension for myself. You highlight a sentence (or press Alt+Q) and it explains it using the paragraph around it, in whatever language you pick. For figures and equations you can’t copy, Alt+Z lets you drag a box around them. It’s free with a daily limit

痛点：非英语母语者读英文论文时遇到难句/图表，必须切换标签到 ChatGPT 或翻译器，既打断思路又丢失阅读位置。

目标用户：以非英语为母语的研究生、科研人员及需要读英文文献的学术读者。

证据：I’m not a native English speaker and I read a lot of papers in English, so I often get stuck on one sentence or one figure and end up switching tabs to ChatGPT or a translator, then losing my place. / It’s free with a daily limit (there’s a paid plan if you need more).

变现：Freemium：免费每日限额，付费订阅解锁更高调用额度；后续可加团队/机构版或按 API 用量分层收费。

MVP：做一个 Chrome 扩展：划词或 Alt+Q 快捷键调用 LLM，把选中句子连同所在段落上下文一起发给模型并用目标语言解释；Alt+Z 支持拖框截取图表/公式走多模态识别。直接复用 OpenAI/Google API，2 周可完成。

竞品：Immersive Translate、Sider、Monica、ChatGPT 浏览器侧边栏插件、Scholarcy

摘要：一位非英语母语开发者因读英文论文时常卡在单句或图表、被迫切标签到 ChatGPT 而丢失位置，自建了 Chrome 扩展 ContextSnap：划词/Alt+Q 用上下文解释句子，Alt+Z 框选图表公式，支持多语言。产品采用每日免费额度+付费订阅模式，基于 OpenAI 和 Google 付费 API。需求真实且受众广，但翻译/AI 阅读类扩展竞争激烈，且帖子仅有作者自述，缺乏他人付费验证。
