## What is Hearth AI?

Hearth AI brings powerful AI chat to your device —        
  completely private, completely offline.                   
                                                            
  100% On-Device AI                                       
  Run large language models directly on your iPhone, iPad,
  or Mac using Apple's Metal GPU acceleration. Your
  conversations never leave your device.

  No Account Required
  No sign-ups, no subscriptions, no cloud. Just download a
  model and start chatting.

  Browse & Download Models
  Explore a curated selection of open-source models from
  Hugging Face Hub, or browse the full catalog. Choose
  models that fit your device's capabilities — from
  lightweight 0.5B models to powerful 3B+ models.

  Smart Document Q&A
  Import documents and ask questions about them. Hearth AI
  chunks and indexes your documents locally for fast,
  relevant answers — all without sending your data anywhere.

   using on-device memory, making your experience more
  personal over time.

  for processing.
