Chatbots · freemium

Cons

- ✓Systemwide app actions work across first- and third-party apps, functioning as an OS-level agent
- ✓Completely free — no subscription tier, included with the OS update
Cons
- ×Locked to Apple ecosystem — no Android, Windows, or web access
- ×Still in beta — real-world performance on cross-app actions and personal context accuracy is unproven
