OnDevice AI

Acerca de esta app

OnDevice AI is a private artificial intelligence assistant designed specifically for iPhone users who require offline functionality and data security. Unlike cloud-based services, OnDevice AI processes all requests directly on the device using Apple’s on-device intelligence framework. This ensures that conversations are never sent to external servers, uploaded to the cloud, or stored outside the user’s device, making it suitable for use in airplane mode, underground transit, or areas with no signal.

The application supports multiple AI personalities, including Professional, Creative, Technical, and Friendly modes, allowing users to tailor interactions to their specific needs. All conversation history is stored locally on the device, and users can export these chats as text files. The app leverages Apple’s Foundation Models to deliver fast and efficient processing capabilities.

It is particularly useful for scenarios such as international travel without roaming charges, studying in rural areas with poor coverage, or handling sensitive professional brainstorming sessions where confidentiality is paramount. The app requires iOS 26.0 or later and an iPhone equipped with Apple Intelligence support. A free tier allows ten messages daily, while a one-time purchase of $29.99 unlocks unlimited messages and full history access.
