Show HN: NotebookLM style mindmap inside ChatGPT
A developer created a NotebookLM-style mindmap interface that runs inside ChatGPT, aiming to replicate the look and feel of NotebookLM within the ChatGPT environment.
Background
- NotebookLM is Google's AI note-taking tool that can automatically generate "Mind Maps" (visual diagrams of connected ideas) from documents you upload. It became popular in tech circles in 2024 for its clean, podcast-like audio summaries and visual overviews.
- "Show HN" is a tag on Hacker News (HN), a tech news aggregator run by Y Combinator, where developers showcase side projects and prototypes to the community.
- This project is a browser extension or custom UI (it's unclear which from the post alone) that replicates NotebookLM's mind-map feature inside ChatGPT's interface — letting ChatGPT users get that same visual summary without switching to Google's product.
- The original Hacker News thread would likely discuss how well it mimics NotebookLM, whether it's actually useful, and potential privacy/security concerns of running third-party code inside a major AI chatbot.
