Atlases and the AI assistant are two separate subscriptions. Buy either, or both — they aren't bundled.

All Atlases and the AI assistant each come with a free two-week trial — everything unlocked during that window. Cancel inside the two weeks and you are not charged. (A single region has no trial.)
Atlas subscription
Subscribe by body region, or take all of them at once.

AI assistant subscription
Free 2-week trial
From $4.99 / month
Ask it about whatever you are looking at. Free two-week trial. It also works without a subscription — there is a free allowance every day. Subscribing unlocks every model and raises the ceiling.
These are starting prices. For the exact tier, monthly vs annual, and the converted price in your region, check the App Store inside the app — that's the source of truth.
Frequently asked questions
How much can I use without paying?
All Atlases and the AI assistant each come with a free two-week trial — everything unlocked, and nothing is charged if you cancel inside that window. The AI assistant also works unsubscribed, with a free allowance each day.
Why are atlases and AI sold separately?
Because people want different things. Some only want the images and never touch the AI; others are the opposite. Keeping them separate means you don't pay for the half you don't use.
Is there a free trial?
Yes. All Atlases and the AI assistant each come with a free two-week trial; cancel inside the window and you are not charged. A single region has no trial — it is already the cheapest option.
How do I cancel?
Settings → your Apple Account → Subscriptions on your iPhone, any time. You keep access until the end of the current period, then it returns to free with no further charges.
Take the two-week trial first
Free two-week trial, everything unlocked. Cancel within the two weeks and you are not charged.
