iPhone Users Run Local AI Chatbots for $5 as Apps Cut Cloud Fees and Data Sharing

3 articles · Updated · Engadget · May 28
  • $5 or less can now get iPhone users a local AI chatbot through apps such as Private LLM and free-to-download Locally AI, letting open-weight models run directly on the device.
  • Those apps pitch three main advantages over ChatGPT, Claude and Gemini: no monthly subscription, no login or prompt sharing with major AI labs, and offline use without an internet connection.
  • The tradeoff is weaker performance than leading cloud models, including shorter context windows, no built-in web search for timely answers, and fewer memory-style personalization features.
  • Locally AI is positioned as the easier starting point, while model size remains the main constraint: Meta's 3-billion-parameter Llama 3.2 needs 1.81GB, versus 695MB for the 1-billion version.
  • Newer phones handle larger models best—the guide recommends an iPhone 15 Pro or newer for the strongest experience, though smaller models also ran on an iPhone 12.
