OfflineLLM: Private AI Chat

OfflineLLM uses a custom execution engine for LLMs, optimised specifically for Apple Silicon on iPhone, iPad, Mac and Vision Pro. Using the full power of Metal 3, OfflineLLM is able to run faster on consumer devices than apps based on llama.cpp and MLC.

Welcome to AI chatbots that can be used without the risk of compromising confidential and sensitive data.

For the first time, you can have personal GPT assistants running privately on your device without an Internet connection. No data is ever sent to the cloud. Your conversations never leave your device. Continue using your AI chatbots when in Airplane mode.

Chat directly with the LLM that powers Apple Intelligence!

Experience multi-modal vision models like never before on the iPhone. Send images to your offline AI chatbots.

Further enhance your AI chatbots using RAG (Retrieval Augmented Generation) to integrate your own documents and files into your LLMs.

Beginner mode allows novices to step into the world of LLMs and AI chatbots.

Advanced mode allows experts to configure every parameter of the LLM execution engine.

Interact with Offline LLM, anywhere and on any device. Extend the app with system Shortcuts, Automations and Widgets.

Offline LLM can run a variety of models, which are capable of running on a range of devices. Performance on devices will vary and depend on the model selected. More advanced models are optimized for powerful Macs and iPads and will struggle to run on older iPhones. To successfully run a model, your device must have more VRAM than the model you choose to use. Large language models perform differently for each question asked; some questions will run significantly quicker or slower than others.
