Show HN: Cai – Local AI Action Layer for macOS (Free, MIT, MLX)

Hi HN, Cai runs actions on your selection via ⌥C, pick an action (AI, shell, GitHub issue, Linear ticket), done. Bundled local model (MLX Community), create custom actions with prompts, scripts and more. Free, MIT. Built after my Raycast extension sat in review queue for 3+ months. Wanted no typing, no app switching, no cloud. Repo: https://github.com/cai-layer/cai https://github.com/cai-layer/cai Demo: https://youtu.be/LH2MYNQ_wsk https://youtu.be/LH2MYNQ_wsk
