 Private LLMPrivate LLMUlogUlog
DescriptionPrivate LLM runs text-based AI models locally on supported iPhones, iPads and Macs. It is a useful alternative for personal writing, summaries and questions when you want an on-device assistant instead of a hosted team workspace. Download a suitable model first; supported models and performance depend on your device and available memory. The US App Store lists a one-time price of $4.99. The developer describes access across supported Apple platforms with Family Sharing for up to six people and no subscription. Check your own store region for the current price and device requirements. Siri and Apple Shortcuts integration can connect the assistant to your existing workflows. The app privacy policy says conversations stay on-device and are not collected by the developer. This is distinct from the product website, which has analytics and a support form, and from the network requests needed to download models. Local processing is useful for controlling your chat data, but it does not establish that every model answer is correct or that every model will run well on every device.uLog is an AI-powered conversational journaling app that helps users track their thoughts, ideas, and memories through interactive conversations with an AI companion. With subscriptions starting at $2/month, users can set customizable reminders, engage in meaningful discussions, and review their experiences through a detailed timeline. uLog ensures data privacy and security and offers a progressive web app for ease of use.
