NackApp

Nack is a user-friendly AI app for chat and image generation for mobile. You can chat with AI, including the GPT4. You can also create stunning images by just describing what you want to see, and you can use Nack's Upscaler to enhance the size and quality of your best photos.  You can also pin your favourite conversations for quick access, rename conversations, search through your chat and prompt history. Your conversation data is also privately stored directly on your device.   It's available on iOS and Android, with the desktop/web version coming soon.
