Greetings again, PH 👋
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

@soyasis amazing, it makes my workflow so much smoother not having to jump back and forth between all different apps I have opened :) I also just found out that there are community extensions - love it!
Glazed
Thanks for the early testing @phiele 🙏
@soyasis Is this working on Windows as well?If yes what are the shortcuts there and are they customizable?
Glazed
@shantanu_singh_parihar Unfortunately no in scope atm, but if we get enough interest we'd be happy to consider :)
@soyasis Sounds like a great tool! Very interesting. Just heads up, I think the preview video sound is mixed up around 2:48-3:15

This looks sharp. What do you think will surprise people most once they actually use it?

@iampascio The minimalism and customization aspect are key, you can create your own actions to fit your workflow (scripts, prompts, destinations...) and even trigger fire-and-forget agents that run tasks in the background while you focus on something else. Curious what you think!
Wow this is really really cool - is this open source - this is what software should be minimal and simple and does what it has to do.

@dhruba_patra thanks for the kind words! Agree, simplicity is king! 👑
