VCrumb AI - YouTube note-taking: Revisit offline, chat & summaries

Hi Product Hunt! 👋 I’m the maker behind VCrumb AI. Like many of you, I spend hours learning from tutorials, lectures, and bootcamps on YouTube. But I noticed a frustrating trend: almost every video note-taking tool out there forces your data onto the cloud, or locks you into expensive monthly AI subscriptions just to study efficiently. I wanted to build a tool that respects user privacy and gives learners full ownership of their knowledge base. That’s why I created VCrumb AI - a local-first, privacy-focused browser extension designed for smart learning. Here is how VCrumb AI helps you learn faster: Active Side-by-Side Study: Take rich-text notes and snap crucial lecture screenshots in real-time right next to the video player - no more constantly switching tabs. 100% Offline Personal Library: Your study notes and captured visuals live entirely on your machine. Revisit your materials anytime, anywhere, without an internet connection. Flexible AI Power (BYOK): Need a quick recap or want to quiz yourself? Plug in your own API key for completely optional, on-demand AI summaries and interactive video chat. Seamless Export: Instantly move your organized study notes into PDF, Markdown, or text format to sync with your existing revision workflow. Whether you are a student, developer tracking technical tutorials, or a lifelong learner, I’d love for you to try it out. I’m incredibly excited to hear your feedback, listen to your feature requests, and help you upgrade your study routine! Thank you so much for the support! 🙏
