## What is E2N?

E2N (Everything to Notebook) is a **Chrome and Microsoft Edge** browser extension that extracts subtitles, text, images, and audio from **Douyin, Bilibili, YouTube, Xiaohongshu (Rednote), Zhihu, and WeChat Official Accounts**, then sends clean structured Markdown to **Google NotebookLM**, **Feishu / Lark**, **Notion**, or **local Obsidian** in one click (up to two destinations per push). Any web page can be clipped via right-click.

**Differentiators:** multi-platform video + social + anti-copy pages (Zhihu, Xiaohongshu); NotebookLM + Feishu + Notion + Obsidian in one extension; local Obsidian via Local REST API; BYOK for OCR/transcription; core text/CC clipping is free.
