Start with the free tier
The household Adventurer plan is $0 with unlimited devices — every phone, tablet, console, and smart plug in the house. You pay only for the AI work used, which for most families runs a few dollars a month.

Takeaway. Unlimited devices at no platform fee means you never have to choose whose phone matters.
