Modem AI
Read full descriptionHide 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.

A1 - AI without the data centers. Every other AI app ships your questions to a warehouse the size of a town — one that drinks water by the reservoir and burns power by the city — then rents the answer back to you by the month. A1 doesn't. A1 runs two ways, and neither needs a data center: • On your phone. A small, capable model runs fully on your device. Nothing is uploaded. No account. • Across the mesh. Or borrow a slice of compute from a decentralized network of real people's devices — no headquarters, no landlord. What you type never becomes someone's training pile. What you ask is never sold back to you. And not a single drop of water is boiled off to answer “hey.” Common sense about thinking machines: a model is just math, and the chip in your pocket is enough to think with. Ask anything. Run it on us, not on the planet. — — — A1 Pro is an auto-renewable subscription. • Price: $9.99 per week (US), with a 7-day free trial for new subscribers. • Payment is charged to your Apple Account at confirmation of purchase. • The subscription automatically renews unless it is canceled at least 24 hours before the end of the current period. • Your account is charged for renewal within 24 hours prior to the end of the current period. • Manage or cancel anytime in your App Store account settings after purchase. • Any unused portion of a free trial is forfeited when you buy a subscription.

Verdict
The clearest difference is in-app purchases: Modem AI at none against A1 ai's 1. Modem AI also leads on device support (4 vs 2) and iOS requirement (15.0 vs 18.0). A1 ai's advantage is update cadence (weekly vs every 7 months). On price and ads there is nothing between them.
