What is in the app
When you are signed in, the tab bar has Home, Shared, Record, Files and More.
Decisions, shared spaces, AI activity, automations and connections open as native screens. Any other screen opens its own page from app.gettrillion.ai inside the app, where you sign in once with your passkey.
Record a voice memo
1
Open Record
Tap Record in the tab bar.

Talk
Your words appear as you say them: settled lines with the moment each was said, and the words still being heard in grey. Scroll back to read while it keeps recording; Back to now returns to the newest words. Recording carries on with the screen locked.
3
Finish
Pause keeps the same memo. Discard throws it away on the phone. Done keeps the sound and a transcript in your Files under Recordings from iPhone, by date, and hands both to your AI.
Formats
Formats (under More) shows the ways you write and speak: your own saved formats first, then the starters every account has, such as a blog post, a newsletter, an X thread, a short video or a YouTube video. Type a thought and every format fills with it at once. Open one to read it as a script in large type, Record it with the script pinned above your live words, or tap Have my AI write it.Add to Trillion from any app

Signing in
Open the app and tap Sign in to Trillion, then use your passkey. The Share sheet uses the app’s sign-in, so if you share before signing in, it asks you to open Trillion and sign in once, then share again.Getting the app
The Trillion iPhone app is not in the App Store or on TestFlight, so there is no public install link. It runs on iOS 18 or later.On Android there is nothing to install from a store either: open app.gettrillion.ai in Chrome on Android, sign in, and install it as an app from Chrome’s menu. Trillion then appears in the Android share menu. After you share, a page shows a preview of what you shared and the same places and instructions as the iPhone sheet; tick the places, pick the instruction, and tap Send. What you share is kept under Shared from Android in your Files.
