Lekh AI is a native iPhone, iPad, and Mac application that runs large language models entirely on the device, keeping all data private. It integrates chat, vision, document analysis, image generation, and voice interaction in a single offline assistant. Users can converse with models such as Gemma, Qwen, Llama, Phi and Mistral, and use Kokoro text‑to‑speech for voice chats. The app is sold for a one‑time fee and does not rely on cloud services.
