does this look vibe coded?

Upload PDFs, videos, and articles to chat with sources and generate flashcards, quizzes, and mind maps.

I built an AI study and research workspace for source-grounded learning I built SolomindLM around a frustration I kept seeing: uploading a lecture or paper to a general chatbot gives you a summary, but it’s hard to keep the work tied to the source. It lets you collect PDFs, slides, notes, web pages, and papers in a notebook, chat with those sources with citations, and generate flashcards, quizzes, written questions, reports, and mind maps from them. I’m sharing it because I want feedback

My first vibe-coded app 🚀 Built with just a few prompts using Claude Code, with full CRUD support. Still amazed at how quickly an idea can turn into a working app with AI-assisted coding. #VibeCoding #ClaudeCode #AI #BuildInPublic

做了十多年视频后期,我 vibecoding 了一个 YouTube 视频分析总结工具 大家好,我是一个做了十多年影视后期的从业者,最近开始学习 vibecoding ,尝试自己做产品。 由于之前工作的需要,随时学习最新的技术,所以需要经常看些教程,比如 C4D 或者 Houdini 之类的,但是这类教程往往都是英文的,对于我这种英文不好的人来说,简直是地狱,看一会就困得不行,尤其是听不懂,只能看操作,一个教程看下来,实际吸收的知识我估计只有 30%左右。出于这个原因,我就考虑做一个学习工具,于是有了这个产品。 这个工具叫 TubeTutor AI: https://www.tubetutor.top 我看过很多现在市面上的 YouTube 工具,主要依赖字幕。用来总结访谈、播客和课程问题不大,遇到屏幕录制、软件教程、代码演示或者旁白比较少的视频,往往需要暂停,来看清楚作者到底操作了什么,或者输入了什么命令,这样无形中浪费了大量的时间。 所以我给 TubeTutor 做了一个视觉分析功能。 它会结合视频字幕和画面,尝试整理视频中出现的工具、网页、代码
