Castor
Spotlight that executes tasks instead of just finding them
Castor is a free, open source AI agent for macOS. Hit a hotkey, tell it what to do — it already knows your Finder paths, browser tabs, clipboard and screen before you ask. Powered by Gemini Flash, built natively for macOS 26 Tahoe.
Hey PH! 👋
I built Castor because I kept switching between Spotlight, the terminal, and AI chatbots to get simple things done. The idea was: what if one overlay just knew your context and acted on it?
It's a personal project, rough around the edges, but I use it daily. Free and open source — would love feedback from this community on where to take it next.
