Press ⌥C on anything to run smart actions, locally
Press ⌥C on anything to run smart actions: AI prompts, shell scripts, GitHub issues, Linear tickets, or send results anywhere... All one keystroke away. Bring your own brain: bundled Ministral 3B for zero-setup local AI, any HuggingFace MLX model for Apple Silicon speed, or connect Ollama, LM Studio, Apple Intelligence, or OpenRouter. Free, MIT licensed. No cloud, no account, no telemetry.
Cai is my attempt to escape the "⌘Tab fatigue" for everyday tasks (eg. copy something → ⌘Tab to Claude → paste, wait, follow-up → ⌘Tab back, paste, copy → ⌘Tab to browser…) Probably 30+ times a day?
I originally tried shipping it as a Raycast extension, but it's been sitting in their review queue ever since, so I decided to build Cai natively from scratch with simplicity, privacy and ownership in mind.
As models keep improving and commoditising, I strongly believe local and privacy-first is the way forward (my Gmail from 2005 is probably in some model's weights now, writing bad poetry to strangers.). Cai aims to become the assistant you own, that runs on your Mac and you never have to think twice about what data you're feeding it.
Cai is free, MIT licensed, and a few amazing people are already helping with ideas and code (massive thanks for your support! 🙏). Everything in the demo runs 100% on your Mac.
Roast it in the thread, I'll be around all day.
Much love,
Asís

Who hunted Cai?
Cai was hunted by Asís. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it.

Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
