Frequently asked questions
What is Niello?
Niello is an AI sticker journal for iPhone and iPad. Snap a photo, Niello cuts the subject into a die-cut sticker, and you compose your day on a journal page — with Mochi, the AI kitten, helping along the way.
How do photos become stickers?
Point your camera at anything — a coffee, a plant, a friend. Niello lifts the subject off the background and turns it into a clean sticker you can place, resize, and tilt on your page.
Is Niello free?
Niello is free to download and journal with, and AI features include a free monthly allowance. Niello Pro unlocks higher limits for heavy sticker-makers.
Which devices does Niello support?
iPhone and iPad running iOS 17 or later. On iPad, Niello supports Apple Pencil for handwriting and doodles.
Is my journal private?
Your journal is yours alone — nothing you write is public. Photos and text are only sent for processing when you use an AI feature; the Privacy Policy explains exactly what is processed.
Which languages does Niello speak?
English, 简体中文, 繁體中文, 日本語, 한국어, Français, Deutsch, and Español — the app and this site speak all eight.
How do I manage or cancel my subscription?
Subscriptions are managed by the App Store. On your iPhone, open Settings → your name → Subscriptions, choose Niello, and change or cancel there.
How do I restore a purchase?
In the app, open the Niello Pro page and tap Restore Purchases. Make sure you are signed in with the Apple ID you originally purchased with.
