Helios is our take on the AI assistant we wish Apple Intelligence felt like in day‑to‑day use. It’s a cross‑app AI that understands what you’re working on and helps you right where you are. It lives as an overlay you can use in any app (Mail, Slack, your browser, notes -- anything), so AI help is always just a shortcut away. Free to use with your own API keys, plus we give you free credits to get started!
