About Notebook OS
Gemini Notebook is brilliant at thinking. Everything around it is friction: copy-pasting URLs, hunting for papers in other tabs, re-typing the same instructions every session, exporting a deck with a watermark. Notebook OS removes that friction: one-click YouTube and academic sources, voice notes straight into a notebook, Skills that make it remember how you work, Studio recipes for decks, reports and quizzes, and watermark-free presenting.
About ContxtAI
Every time I switched between ChatGPT, Claude, and Gemini, I found myself rewriting the same project context, preferences, and goals. I built ContxtAI to fix that. It’s a free, open-source, privacy-first Chrome extension that lets you create reusable context profiles and use them across AI platforms. Build Context Once. Use It Everywhere. Keep your context local, private, and always under your control.
