About this extension

Everything to Notebook (E2N) — Firefox extension to clip video subtitles, articles, and research into clean Markdown for Google NotebookLM, Feishu (Lark), Notion, and Obsidian

Built for students, researchers, and knowledge workers who collect material across the web. E2N turns page text, CC subtitles, on-page summaries, images, and audio into structured notes—then syncs to the knowledge bases you configure.

Common use cases
• Turn long tutorial or course videos into searchable notes (subtitles + summaries, no manual transcription)
• Export multi-part series or playlist-style collections when you stay on an authorized video site
• Capture articles, image-heavy posts, and charts without broken formatting from copy-paste
• Build a research library in NotebookLM, team docs in Feishu, structured Notion databases, or local Obsidian vaults

What you get
• Video notes: CC subtitles, platform summaries where available, and batch-friendly exports from channels or lists on supported sites
• Rich posts: clean article Markdown with images; Pro adds multi-image OCR for screenshots and diagrams
• Universal clipper: right-click any page to extract the main reading content
• Flexible destinations: NotebookLM, Feishu/Lark, Notion, Obsidian — choose up to two active targets per push

Free vs Pro
• Free: text, subtitles, summaries, source URLs, and right-click clipping
• Pro (BYOK): optional OCR and speech-to-text with your own API keys (purchase at e2n.studio)

Privacy
• Keys and destination tokens stay in your browser. Content is processed only for exports you start. Anonymous product analytics disclosed at e2n.studio/privacy.
