Nyth AI

Nyth AI is a private artificial intelligence chat application made for iPhones and iPads. It brings strong AI abilities right to your device without sending your talks to outside computers. This means your chat messages stay on your device, keeping your conversations private. You do not need to create an account to use Nyth AI, making it a great choice for people who care a lot about their privacy.

Nyth AI uses different "brains" for various jobs. Flash is for getting fast answers. Nova is for general chatting and coming up with new ideas. Sage is for more complex thinking, working with code, and doing analysis. You can pick a specific brain for your needs or let "Smart Routing" choose the best AI model for what you are doing. You can change brains whenever you want.

The app allows you to talk naturally using your voice. It can understand what you say and read replies out loud, all on your device. It has an easy way to record and play back voice messages. Nyth AI also includes helpful features like an introduction guide, a history of your conversations, and the ability to save your chats as JSON files. You can easily copy the AI's answers, and the design works well for chatting and typing on iPhones and iPads.

AI processing happens on your device after you download a language model. This download happens only once over Wi-Fi from Hugging Face. The models are usually between hundreds of megabytes and about 1.5 gigabytes in size. Once downloaded, these models work even without an internet connection. Nyth AI is useful for professionals, students, writers, and developers who need a capable AI tool that respects their data privacy.

Nyth AI is available for iPhone and iPad with iOS 18.6 or later. It also works on Mac computers with macOS 15.6 or later and an Apple M1 chip or newer, and on Apple Vision with visionOS 2.6 or later. The app is in English and is rated for ages 9 and up.
