Indie developer crafting productivity tools. Creator of Bookshelf for
Hey! I'm an indie developer from Japan, building small productivity tools that make everyday workflows smoother. I created "Bookshelf: Folder Manager for Gemini Notebook" — a Chrome extension that adds folders and subfolders to Gemini Notebook (formerly NotebookLM). It started as a personal fix for my own 50+ notebooks, and it's now been installed over 40,000 times.

On privacy: your notebooks and folder data stay in your browser — I never see them. The extension does send anonymous usage counts (how many folders, which features get used) so I can tell what's worth improving. Nothing that identifies you.
