Starcat is a native, local-first macOS app that turns messy GitHub Stars into a searchable, AI-powered knowledge base. Organize repositories with tags, notes, status and smart filters; get AI summaries and tag suggestions, track releases, and rediscover useful projects fast. Unlike browser bookmarks or cloud-first Star managers, Starcat keeps your data on your Mac, supports your own AI keys, and lets AI suggest—not decide—so you always stay in control.
