First launch

Take the tour

The first launch opens a five-page introduction to Cella. Swipe left or use Next to move through it. The last page takes you to Home.

To leave early:

1. Tap Skip.
2. Turn on Don't show again if you do not want the tour on your next launch.
3. Tap Skip again to confirm.

If you cancel the confirmation, the tour continues where you left it.

Choose an AI option

Cella can save documents without AI, but an available AI engine is needed to organize them, read useful details, and answer questions.

You may be offered two private, on-device choices:

• Apple Intelligence is built into supported iPhones. It requires iOS 26 or later, eligible hardware, and Apple Intelligence enabled in the iPhone Settings app.
• Gemma 4 is an advanced model that downloads into Cella and runs on supported Apple Silicon hardware.

Choose one of these options:

• Apple Intelligence: Turn on Apple Intelligence in your iPhone's Settings app, then return to Cella.
• Gemma 4: Start the download in Cella and wait for it to finish.

You only need one option. Cella automatically checks whether your chosen option is ready to use.

Good to know: Tap Not Now if you want to continue without AI. Your item can still be saved, but it may remain unorganized and Ask AI will be unavailable until you configure an engine.

Understand your two vaults

• The Default vault is the normal place for your documents.
• The Private Vault is a separate, PIN-protected area available on Plus and Max plans.

Home shows only one vault at a time. You can switch later from More (the three dots) at the top of Home.

Start without an account

Cella does not require an account or sign-in. Your working vault is stored on your iPhone. Before adding important documents, review Backup and Restore so you know how to protect them from device loss or app deletion.
