痛点：网页内容无法像 PDF 一样被标注、划线和手绘批注；阅读长文时笔记和原文容易脱节。

目标用户：重度网页阅读者、研究者、学生、需要从文档网站摘录资料的知识工作者

证据：I remember thinking, why can I annotate a PDF but not a web page. / I showed a friend and they asked if they could draw on it.

变现：Freemium：免费基础标注，Pro 订阅或一次性买断解锁手绘墨迹同步、AI 摘要、跨设备笔记导出；或作为浏览器扩展卖给教育/研究团队批量授权。

MVP：不做浏览器，先做 Chrome/Edge 扩展：Reader 模式 + 文本高亮 + 便签 + 按 URL 保存标注，数据存本地 IndexedDB 并支持导出 Markdown；两周内可上线，验证后再加手绘和 AI。

竞品：Hypothesis、Glasp、Weava Highlighter、Readwise Reader、Memex、MarginNote、Microsoft Edge 内置 PDF/网页批注

摘要：作者因无法在网页上像 PDF 那样标注，独立开发了 Windows 浏览器 Quill，支持阅读模式分屏、按 URL 保存手绘墨迹、便签和 AI 面板。帖子只是发布展示，没有公布定价、收入或用户数据，只有一位朋友的口头需求反馈，付费意愿尚未被验证。网页标注方向已有 Hypothesis、Glasp、Readwise Reader 等众多竞品，但以轻量扩展形态切入仍有空间。
