I built a free Chrome extension for NotebookLM — 0 to launch as a solo dev

Hey IH,

I've been using NotebookLM daily for research for over a year.

Great tool — but the workflow has real friction:

- Importing web pages is tedious (copy URL → switch tab → paste → repeat × 20)

- No way to track where sources came from weeks later

- No connection between NotebookLM, Obsidian, and Notion

I looked at existing extensions — they each solve one thing but don't

talk to each other. So I spent the last few months building NotebookLM Hub.

What it does (v0.1 — shipped):

- One-click import from any webpage via side panel (~2 seconds)

- Smart annotations: auto-timestamp + source tag on every import

- Pick Links: extract all links from a page, batch-import the ones you want

- Source management console with real-time status tracking

- Bilingual (EN/CN)

Stack: Chrome Extension Manifest V3, React, Zustand, Vite

Current status:

- Live on Chrome Web Store (free)

- First users coming in from HackerNews Show HN

What's next (M2):

- Obsidian bidirectional sync

- Notion OAuth sync

- Batch URL import

- YouTube import

Biggest challenge so far: Reddit keeps removing my posts (new account

karma issue), so I'm finding other channels.

Would love feedback — especially from anyone who uses NotebookLM heavily.

What would make this worth installing for you?
