Ask about anything, then follow it anywhere.
Ask about Mount Everest and a card opens beside the answer, with doors to the Himalayas, Nepal and the eight-thousanders. Tap one, then the next. It is easy to get lost for hours.

-5.28 g CO₂e · 11 redwood-minutesAnswers are written on your iPhone by default, and it counts what that saved.
Every answer is a doorway.
Half a million topics are built into the app, so the facts open at once, even in airplane mode. Every card ends in more cards, and the index grows from what you tap, right on your iPhone.
Places
A map, what is nearby from Apple Maps, and how long the drive is from where you stand.
Dishes
More than 3,000 come with a recipe, and every ingredient leads to the recipes that use it.
Films and shows In 1.0.1
The poster, a summary, the trailer, and what it costs to rent or buy. Theaters near you link to their showtimes.
Weather In 1.0.1
The next hour, the next twelve, the week ahead, from Apple Weather. Planning a trip? It knows what those dates are usually like.
Your calendar In 1.0.1
Your day as cards, each with its place on a map. Tap Weather then, and the question is written for you.
The web
Links open in a small browser inside the app. Ask about the page or get a summary. It keeps no history and no sign-ins.
Answers can be wrong, so check anything important.
It counts what it saved.
Every answer written on your iPhone is one a datacentre never had to write. Corollary keeps the tally in grams of CO₂, and in how long one coast redwood takes to breathe them back in.
It counts at the low end of published per-answer figures, so the number never flatters itself.

Yours, on your phone.
Nothing you ask is sent to us. There is no account and no analytics. When the app does reach outside, for a map, a page or the weather, Settings › Agent log lists what it sent and where.
Answers on your iPhone by default
Apple Intelligence writes them on the phone. For more, choose Apple’s Private Cloud Compute, an open model downloaded to the phone, a model on your own computer, or your own key for Anthropic, OpenAI or Google Gemini. The app asks before anything is sent.
Your calendar stays on the phone
It is read only, and only when you ask. It leaves the phone only if you choose a cloud model to answer, and a question that needs the web never carries it.
Each answer lists its sources
When a question needs the web, the app reads public pages and data, such as Wikipedia and Wikidata. Those sites see the words being looked up and your IP address, never your conversation.
Your chats live on your iPhone
Chats, bookmarks and the games you make are stored on the phone. Delete the app and they go with it.
Ads that know nothing about you
Ads appear only when making games. They are never personalised, and your questions are never part of an ad request.
Coming in 1.0.1
Already built, and going to Apple once 1.0 is approved.
