AI Photo Editor No Sign Up – Edit Photos with Prompts
Mock up gallery wall layouts to scale with your photos before hanging real frames.
u/Individual_Plane5170 · Reddit
I built a free, open-source gallery wall planner because the good ones are paywalled My wife and I were decorating a big wall and couldn't agree on a layout. I wanted to place real frame sizes with our own photos and see it to scale before drilling. Tools exist (GalleryPlanner, Suprtiles…), but the good ones paywall the useful bits or felt heavier than I needed. So I vibe-coded a stripped-down one over a evening.

做了个托管 PDF 的二维码工具 最近老婆一直在抱怨给老外传 pdf 文件很麻烦，之前一直是走邮件附件。麻烦在于文件一改就得重发一遍，对方手上可能还留着旧版本，来回确认到底看的是哪一版特别费劲。 想着不如给她生成个二维码或者短链接，文件更新了直接换后面的，链接不变。搜了一圈现成的工具，试了几家都有点别扭。有的免费能生成，点下载却要注册。还有的会在扫码后的落地页上放广告，但那是发给客户看的东西，不太合适。 干脆自己做了一个： https://qrcodeforpdf.app 传个 PDF ，出一个二维码和短链接，扫了在浏览器里直接打开，不用下载也不用装 App 。文件可以随时替换，码和链接都不变，已经发出去或者印出去的都还能用。不注册就能生成和下载，PNG 和 SVG 都没有水印，应该是比较完美的，刚好也作为自己的一个小项目，也欢迎大伙们试用给建议，逐步优化！
