Tired of messy, inconsistent phone number formats in your contacts?

Benefits include improved contact organization (ensure all your phone numbers follow a consistent and professional format) and simplified international calling (easily identify and dial international numbers with the correct prefix). Your phone numbers are processed locally on your device and are never stored, shared, or transmitted. e.164: The international standard format (+15555648583) ensures seamless global communication and compatibility with various systems. International: A more readable international format (+1 555-564-8583) with spaces and hyphens for easy dialing and identification. National: The familiar national format ((555) 564-8583) commonly used within North America. This app is open source.

About

Modem AI

Features
Read full description

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.
