On the web

Most of what you read for a project is scattered across your browser: an article, a video, a thread, a chat with an AI, a PDF, a shared doc. Notebook Clipper puts any of them in a notebook in Gemini Notebook (formerly NotebookLM) as sources, so you can ask questions across everything you gathered instead of hunting through tabs. Every page can be added from the side panel; on YouTube, X, Reddit, the AI chats, PDFs and Google Docs there is also a button next to the site’s own controls. The guides are grouped by site.
