Built a free Chrome extension to save AI chat, articles and more to NotebookLM
While prepping for interviews I got into this workflow where I'd discuss topics with Claude/ChatGPT, read through Medium posts, GeeksforGeeks articles, the usual. Then I'd dump everything into NotebookLM so I could query it later, generate summaries, study plans, mind maps. It's genuinely great for that.
The problem was actually getting stuff into it. Every time I wanted to save a conversation or an article, I had to copy the text, save it as a file, then upload it. Do that 10 times a day and it becomes its own job.
I looked for an extension that could just... do this automatically. Found a couple but they were paid or only handled one type of content. So I built my own.
It's called ContextKit for NotebookLM. One click saves:
- AI conversations from ChatGPT, Claude, Gemini (full chat or selected messages)
- Web pages and articles (Medium, GFG, whatever)
- Reddit and Twitter/X threads
- Highlighted text on any page
- Multiple tabs at once
- Google Docs, screenshots, clipboard content

Launched about 6 weeks ago, no promotion, somehow at 140 installs. Still using it myself daily and adding stuff. If you try it, let me know what's missing or broken.
