Modem AI is a private assistant for iPhone, iPad, and Mac. It runs a language model on your device, so your conversations stay there. There is no account, and your prompts stay on the device rather than going to a cloud chatbot. The first launch downloads Phi-3-mini, about 2.7 GB. After that, you can chat without a connection. Replies can take longer than a cloud service. That is the trade for keeping the conversation on the device. The model needs about 4 GB of available memory. What you can do • Chat in natural language, including answers with lists and code • Dictate a message with on-device speech recognition. Audio stays on the device • Write a system message, and set temperature, top-p, and maximum response length • Choose light, dark, or system appearance • Copy a reply, start over, or clear history Privacy Your prompts and replies stay on the device. Modem AI does not read them. If you send feedback or report a reply, only what you choose to submit is shared. The app may send anonymous performance statistics, such as whether a feature succeeded. Those statistics do not include your conversations.
