Pictures, films and music, made on your iPhone.
Cloudless AI is an iPhone app. The AI runs entirely on the phone. There is no account, and nothing you type or make is sent to a server.
Needs iOS 26.4 or newer. Pictures, films, sound and music need an iPhone 15 Pro or newer. The instant tools work on iPhone 11 and newer. iPad and Mac versions are coming.
Two films from the phone
Both films were made by Cloudless AI on an iPhone 17 Pro, from the same description. Each one is 5 seconds long and took about 2 minutes. We re-compressed them for this page; nothing else was changed. They are silent: sound is optional and was not added.

Why on the phone

Your work stays with you
The descriptions you type and the pictures, films and music you make stay on your phone. Nothing is sent to a server.

What you can make
Instant tools

- Blur the background
- Enlarge ×4
- Erase
- Add words
Each tool fetches one small model the first time you use it.
Photo and Change a picture
Photo makes a picture from a description. Change a picture works on one of your own pictures. The picture model is about 3.7 GB. A photo takes about 25 seconds on an iPhone 17 Pro. The first picture after a download takes a few minutes, while the phone prepares the model.
Make a video
Films of 5 or 10 seconds, tall (480 × 832) or wide (832 × 480). Start from a description or from a picture, with sound if you like. A 5 second film takes about 2 minutes on an iPhone 17 Pro.
Sound and music
Sound effects for your films, and Compose music: a piece from 10 seconds to 2 minutes long, made from a description. Both use Stable Audio 3 Small.
Powered by Stability AIHow the films are made
As far as we know, Cloudless AI is the first app you can install on an iPhone that runs a 5-billion-parameter video model’s main network on the Neural Engine.
The video model
FastWan 2.2 TI2V 5B, from the Wan 2.2 family, released under the Apache-2.0 licence. Its main network runs on the Neural Engine. The text and picture encoders run on the graphics chip.
A one-time preparation
After you install the app, and again after each update, the film model is prepared for the Neural Engine. This happens once and takes about 12 to 25 minutes. Keep the app open and plug the phone in if you can. The phone gets warm. If you lock it, it carries on, but it can take 4 times longer or more.

Questions
Is anything I make uploaded?
No. The descriptions you type and the pictures, films and music you make stay in the app on your phone until you delete them. A picture or film goes to your photo library only when you press Save to Photos.
Does it need the internet?
Only to download the models, once. After that it works with no internet. While a model downloads, the host that serves it can see your phone’s internet address, as with any download.
Why does it need an iPhone 15 Pro or newer?
Photo, films, sound and music need 8 GB of memory. The iPhone 15 Pro and newer models have it. The instant tools are small and work on iPhone 11 and newer.
Why is the first film slow?
After you install the app, and after each update, the film model is prepared for the Neural Engine. This takes about 12 to 25 minutes, once. If you have not done it before, your first film does it.
How long does a film take?
About 2 minutes for a 5 second film on an iPhone 17 Pro. The phone gets warm and may pause to cool down. If Low Power Mode is on, or the phone is already hot, the app tells you before it starts.
Is there a safety check?
Yes, always on, on the phone. Descriptions that ask for nude, sexual or abusive content are refused. The picture you start a film from is checked, every picture is checked, and seven moments of every film are checked. The checks report to no one.
How do I free up space?
In the app, open Models and remove the one you do not need. You can download it again later.
What about iPad and Mac?
Versions for iPad and Mac are coming. The beta is for iPhone.
