The Take

It maps seven detected content types to one‑key actions — convert invites to calendar events, jump addresses into Maps, or run custom prompts — and even ships a local MinistraI 3B runtime so nothing leaves your machine. Smart, keyboard‑first ergonomics and app‑aware responses make it genuinely useful; the hard part now is building enough action templates or integrations to outcompete Raycast/Alfred clones.

Post Description

I've spent a lot of time copy-pasting and switching between apps to summarize text, create events, proofread emails, look up addresses — always the same follow-up steps after copying.

So I built Cai. It sits in the menu bar. Press Option+C, it detects what you copied and shows relevant actions. Ships with llama-server (Ministral 3B) so it works out of the box, or connect Ollama/LM Studio if you already use them.

Free and open source. Would love feedback on what content types or actions to add next.
