ContextBox

Save useful bits from any webpage and paste them into any AI chat — no sign-up, no uploads.

Stop copy-pasting bits of web pages one at a time. ContextBox is a sidebar that sits next to any webpage. Highlight text, save entire pages, or drop in code files — organize them into groups and copy everything at once into any AI. No sign-up. No uploads. Everything stays in your browser. WHY INSTALL IT If you use AI tools daily for research, coding, or writing, you know the routine: find something useful on a page, copy it, switch tabs, paste it, go back, find the next thing, copy again, switch again... ContextBox removes all that friction. Collect as you browse. Paste once. HOW IT WORKS 1. Browse normally. When you see something worth saving — a paragraph, a code block, an entire article — highlight it and right-click "Sendidebar button. 2. Everything lands in your Box, organized into groups however you like. Drag in local files too (.txt, .md, .js, .py, .json, and more). 3. When you're ready, click "Copy all" and paste the complete bundle into any AI chat. All content stays in your browser — nothing is ever uploaded. WHAT YOU CAN DO - Highlight text on any page and save it instantly - Save entire pages with title, URL, and clean body text - Drag in local code and text files - Organize items into named groups for different tasks - Edit titles and content inline before copying - Pick a theme you like (6 color options) - Switch between English and Chinese PRIVATE BY DEFAULT ContextBox stores everything in your browser's local storage. There is no account, no server, no sync, and no telemetry. Your content leaves your machine only when you paste it somewhere yourself. Use it offline. Use it without signing in. It just works. --- 别再一段一段地复制网页内容了。 ContextBox 是一个常驻浏览器侧边的收集器。浏览网页时看到有用的文字——选中它、整页保存、拖入代码文件——按分组整理好，一键全部复制到任何 AI 工具 存在你的浏览器里。 为什么需要它 如果你每天都在用 AI 做研究、写代码、写文章，你太熟悉这个流程了：在网页上发现了有用的东西→复制→切到 AI 标签→粘贴→再切回去→再找下一段→再复制→再切换…ContextBox 就是来解决这个问题的。 边浏览，边收集。一键贴走。 怎么用 1. 正常浏览网页。看到值得保存的内容——段落、代码块、整篇文章——选中文字后右键选择「发送到 ContextBox」，或者点击侧边栏的「选中文字」按钮。 2. 收集到的内容会按你建的分组整理好。也可以把本地文件直接拖进去（支持 .txt .md .js .py .json 等）。 3. 收集完了，点一下「一键复制」，把所有内容一起粘进 AI 对话框。所有内容都只在你的浏览器本地，不会上传。 你可以这样用 - 选中网页上的任何文字，一键保存 - 保存整个页面，包含标题、网址和正文 - 把本地代码文件和文本文件拖进去 - 给不同任务建不同的分组 - 复制前编辑标题和内容 - 选一个看着舒服的配色（6 种可选） - 中英文界面随时切换 隐私默认就安全 ContextBox 把数据都存在浏览器的本地存储里。没有账户、没有服务器、没有同步、没有埋点。你的内容只有在你手动粘贴时才会离开你的电脑。 离线也能用。不登录也能用。打开就能用。
