Free in-browser PDF tools for merging, splitting, converting, and editing without uploading files.
u/Key_Caramel_5578 · Reddit
Built a free PDF toolkit solo (with AI help) — need feedback on the in-browser text editor before I keep pushing on it Been heads-down on this for a while: thepdftool.in Standard PDF stuff : merge, split, compress, convert, OCR — but most of the conversion tools run entirely client-side (WASM), so files never leave your browser for those. Built solo, leaned on AI tools for a good chunk of the code and debugging. The feature I care most about right now is an inline text editor :— click i

AI assistant that instantly converts your thoughts into organized tasks, notes, and contacts.
u/Firenze30 · Reddit
I built an AI personal assistant that turns brain dumps into tasks, contacts, and notes. No filing required My job requires me to work across multiple projects at different scopes. Recurring monthly tasks, one-time requests, long-term initiatives, operational work. Things come at me from emails, chat messages, meetings, and verbal conversations. And the worst part is getting asked about a project decision from months ago. That decision could be buried in an Outlook email, a Wo

做了个把房源照片自动做成视频的小工具: ReelHive 之前在折腾海外房产相关的项目,跟几位 real estate agent 聊下来,发现一个很典型的痛点: - listing 照片都有,而且通常拍得不错(摄影师外包) - 但是业主 / 中介越来越要求「要有视频、要有 Reels / TikTok 」 - 真正去剪视频很花时间,请人做视频又贵,而且每套房子都要重复同样的活 大部分“照片生成视频”的工具,本质都是把一堆 JPG 丢进时间轴,统一套一个 pan & zoom 模板,最后效果很像 PPT 幻灯片,真实用户反馈是: “有视频是有了,但拿不出手,反而拉低了 listing 质感。” 所以我最近做了一个小工具 [ReelHive]( https://reelhive.app),专门给房产经纪、房产摄影师、marketing team 用来「把现成的房源照片快速变成可用的视频」。 简单说一下它在做什么: 1. 你把一套房子的 listing 照片丢进去(支持一次多选上传),按你希望的顺序排好。 2. 选择一个风格:Luxury / Mo

独立开发了一个「图片转 AI 绘画 Prompt」的小工具,欢迎体验 大家好,最近利用业余时间做了一个小工具站 Find Image Prompt ( https://findimageprompt.com ),主要是想解决自己平时刷到好图、 但写不出对应 prompt 的问题,顺手做出来给大家用。 目前有四个小工具: - 图生 Prompt ( Image to Prompt ):上传一张参考图,生成保留构图、 光影、风格的详细 prompt - 文生 Prompt ( Text to Prompt ):一句话想法扩写成结构化的 prompt - AI 图片描述( Image Describer ):拆解一张图的主体、氛围、构图 - AI 生图:直接拿 prompt 出图,方便对照迭代、反复微调 不需要注册,有免费额度可以直接试。生成的 prompt 是比较通用的 描述性语言,理论上换到 Midjourney / SD / 其他模型也能用。 刚上线不久,功能还比较简单,欢迎大家来体验,有 bug 或者想加的 功能欢迎在帖子里说,我会尽量回复。
