About

smartLLM

Features
Read full description

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 • smartLLM Pro (one-time purchase): search and download additional GGUF models 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 • Downloading the default model and chatting are free. 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, and for in-app purchase features through the App Store (StoreKit), such as loading the price, purchasing, and restoring. 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.
