smartLLM runs a real large language model entirely on your iPhone. Your chat messages are never sent anywhere — every answer is generated by your phone's own chip. • Fully on-device inference (powered by llama.cpp) • Chat messages never leave your phone — no server, no account, no sign-up • Browse and download GGUF models straight from Hugging Face, inside the app • Checks your device's memory before downloading, so you don't end up with a model your phone can't run • Streaming responses, multi-turn chat history, stop generation anytime • Free, with no ads and no subscription ABOUT "OFFLINE" Chatting is fully offline. The app only uses the internet when you search for or download a model from Hugging Face. A NOTE ON AI CONTENT Answers are generated by a language model and may be inaccurate or inappropriate. Please verify anything important yourself, and don't rely on it for critical decisions.
