I built a tool to collaborate on HTML artifacts like a PowerPoint As a consultant, I've watched artifacts become more common as a way to communicate ideas and insights, both internally and with clients. The problem is there's no good way to comment on them, collaborate, or make quick edits; so in practice, they're slow to actually use. I built a free tool that lets you leave comments and edit directly, all while sharing with your team. After you make your edits you can export

周末到啦 介绍一个更加通用的 AI 导盲犬 Ampcode 推出的 Orbs 非常好用 但是反反复复提交图片 debug 会有点心累 现在远程 vibe coding 开发的场景越来越多了 agent 的识图能力也越来越强 但是如何给 agent 传递且描述准确的信息成了瓶颈 像 cursor design mode 这种好用的工具并不在大多数地方提供 尤其是画面动态变化的时候 或者步骤较多的时候可能需要多次标注以及关键帧引导才行 Markup Relay 作为 SUB&SUB 工作室第一个构想的开源产品提供了一个还在不断完善的思路 来作为 agent 的导盲和接力助手 让标注的内容能够被 agent 读懂 即便是视频 也可以方便的提取关键帧来描述画面的变动 https://tools.subnsub.com/relay 使用方法很简单 在桌面端浏览器内 你可以通过拖动支持的文件到窗口内进行快速编辑 如果是框选工具 在处理完毕后会对未框选的区域在浏览器端自动打码并上传至 cloudflare 的 R2 桶 并在设定时间内自动删除 https://i.

dzzz.ai over 90 tools in one website privacy focus Hey r/SideProject , I kept uploading private invoices and contracts to random "free PDF tool" sites just to compress a file. Eventually it occurred to me that the browser can do this locally — so I built dzzz.ai : over 90 tools that run entirely on your device. PDF compress/merge, video trim and conversion, background removal, HEIC→JPG, document scanning with your camera, audio transcription, CSV cleanup. All WebAssembly — ffmpeg, Ghost
