Overview
AI-powered YouTube summaries and structured knowledge capsules to help you learn smarter.
MindCapsule for YouTube is a privacy-first AI learning assistant for YouTube. When you're watching any captioned knowledge video on YouTube, it turns the content into structured "knowledge capsules" so you can grasp the essentials quickly and review them later with ease. Key Features: • One-click summaries: Generate AI-powered summaries, key takeaways, and study notes for the current YouTube video. • Knowledge capsules: Save and revisit structured learning cards built from any video. • Multiple AI providers: Supports OpenAI, SiliconFlow, and custom OpenAI-compatible endpoints. Your API key is configured and kept by you. • Bilingual UI: Switch between Chinese and English interface instantly. • Export notes: Copy or organize AI-generated learning content for use in Notion, Obsidian, Lark, or any note-taking tool. • Lightweight & fast: Open the extension from the toolbar or sidebar without interrupting your viewing experience. MindCapsule does not collect your personal data or silently access unrelated websites. All settings and learning data stay locally on your device, and AI requests are sent directly to your chosen provider using only your own API key. Turn every YouTube video into your personal knowledge capsule.
