## What is Theo8080?

Theo8080 is a private, on-device AI assistant for people who want to use AI more personally and more privately on iPhone and iPad.

Your prompts and conversations stay on your device, not on someone else’s server. Theo8080 lets you download local models, chat privately, and shape how the assistant responds to match your needs.

With Theo8080, you can:

• Chat with local AI models on your iPhone or iPad
• Download models from Hugging Face, a widely used repository for AI models
• Keep your prompts and conversations on device
• Adjust response style and behavior with model settings
• Review and manage your conversation history
• See helpful performance details like response time and generation speed
• Use vision-capable models to chat about photos from your library

Theo8080 gives you control over settings like temperature, context, and system prompt, so you can fine-tune the experience while keeping everything local.

Built for a fast, native experience, Theo8080 supports efficient on-device AI on compatible Apple devices. But please keep in mind that AI can make mistakes, so always check important information and avoid relying on open models for certainty.
