Spike Studio vs Ultra AI Chat

Meet Spike Studio: AI chat on your iPhone, with a choice of where your model runs. GET STARTED WITH SPIKE CLOUD Create a free account in the app, verify your email, and start chatting. You do not need a computer or your own server. Free usage limits apply. This version offers no in-app subscriptions or purchases. USE YOUR OWN MODELS Connect an OpenAI-compatible server, including LM Studio, or download an on-device model on a supported iPhone. These options do not require a Spike account. Model downloads need available storage, and on-device performance depends on your iPhone and the selected model. CONNECT YOUR COMPUTER Use an account-linked Runtime from Spike Studio on your computer, and follow Agent work from your iPhone. Computer and Runtime setup are required for these optional features. KEEP YOUR CONVERSATIONS TOGETHER Sign in with the same Spike account across devices to sync encrypted conversations. Organize chats in projects and choose tools for the task at hand. Tools that use iPhone features request the relevant permissions. Cloud chats are processed by Spike Cloud; on-device models run on your iPhone; a connected server processes the chats you send to it. Choose the option that fits your needs.
