Nack

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 enhance the size and quality of your best photos.

You can also pin your favourite conversations for quick access and 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.
