NoCatch - Universal Google NotebookLM Harvester

Universal Google NotebookLM Media & Artifact Harvester
Official Product of Lorapok Labs • Hosted at nocatch.lorapok.tech

GitHub Release npm version Packagist Version Discord Bot License: MIT Zero-Trust

🌟 Overview

NoCatch is the definitive, zero-loss extraction engine for Google NotebookLM (formerly Project Tailwind). It allows developers, researchers, and creators to download Audio Overviews (podcasts), transcripts, briefing documents, study guides, FAQs, mind maps, notes, and cited sources in 1-click — as single items or bundled completely at once.

💎 Key Features

  • ⚡ Direct RPC Protocol Harvester: Communicates with Google's internal v9rmvd batchExecute protocol directly in <2 seconds. No flaky headless browser overhead required for public artifacts.
  • 🎙 Pristine 128kbps AAC (M4A) Audio: Resolves high-fidelity Google CDN streams directly from drum.usercontent.google.com with original metadata and duration tags.
  • 📦 Single Item or "Download Everything" (ZIP Bundle): Download an individual podcast episode or bundle audio + synthesized markdown notes + source citation manifests into a single indexed ZIP archive.
  • 🌐 Alive Cybernetic Web Application: Hosted at nocatch.lorapok.tech featuring real-time soundwave visualization, interactive cyber player with waveform scrubbing, speed multipliers (0.75x to 2x), and instant download triggers.
  • 🤖 Dedicated Discord Application & Bot: Ingests Discord message links, auto-detects NotebookLM links in server channels and DMs, and generates rich embeds with download buttons.
  • 🧩 Cross-Browser Social Media Extension: Injects a 1-click download bar directly on notebook.google.com and renders a floating ⚡ NoCatch badge on Discord Web, X (Twitter), Reddit, LinkedIn, Facebook, and Slack.
  • 🦾 Loragent Ecosystem Agent: Integrated into Loragent as loragent-nocatch (/mnt/NewVolume/Personal_Projects/loragent/agents/loragent-nocatch/SKILL.md).
