# ImmersiveReader(沉浸阅读) > A local Windows reading system that unifies Zhihu archiving, podcast transcription, and Markdown deep-reading in one library. Spotlight focus mode is inherited from MMbook. ImmersiveReader is the successor to **MMbook**, **PodcastTranscriber**, and **Zhihu Packer**. Those repositories are deprecated/archived; all new development continues here. ## What ImmersiveReader does - **Unified local library**: books from Zhihu, manual Markdown imports, and other sources live under one Documents library with per-book `manifest.json` and reading progress. - **Markdown deep reading**: spotlight focus mode, themes, search, TOC, inline paragraph editing (from MMbook). - **Podcast transcription**: audio/video → polished bilingual Markdown notes (from PodcastTranscriber). - **Zhihu archiving**: pack long-form Zhihu content into the same library (from Zhihu Packer). - **Deep read + continuous read**: desktop immersive reading; browser continuous reading shares progress with the desktop app. - **Privacy-first**: content, progress, credentials, and models stay on the local machine. ## Links - Product site (this page): https://immersivereader.vercel.app/ - Source code: https://github.com/lingcang728/ImmersiveReader - Issues / feedback: https://github.com/lingcang728/ImmersiveReader/issues ## Deprecated predecessors - MMbook: https://github.com/lingcang728/MMbook (archived) - PodcastTranscriber: https://github.com/lingcang728/PodcastTranscriber (archived) ## Stack - Desktop: Tauri 2 + Svelte 5 + TypeScript + Rust - Podcast runtime: Python + faster-whisper (+ optional DeepSeek / Ollama) - Zhihu runtime: Node + local Chromium profile - Storage: local filesystem library under Documents ## Author 凌苍 (LingCang) — independent developer.
