Spike Studio vs ApiRelay

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.

ApiRelay is a private vault for the API keys you use with AI platforms and developer tools. STORE KEYS SAFELY Keep key secrets in the system Keychain. Metadata syncs with iCloud; key secrets sync through iCloud Keychain with end-to-end encryption between your own Apple devices—not uploaded to an ApiRelay server. ORGANIZE & ASSIGN Group by platform or by the tools you use. Assign keys to consumers so you always know which key belongs where. COPY WHEN YOU NEED IT Reveal or copy a secret after optional identity confirmation (Face ID, Touch ID, device passcode, or master password—you choose). Copied secrets can auto-clear from the clipboard after a timeout you set. FREE & ONE-TIME UNLOCK Store a limited number of keys for free. Unlock unlimited keys with a one-time In-App Purchase. Restore Purchases is always available in Settings. PRIVACY-FIRST No ApiRelay account. No analytics SDK. The app helps you keep and hand out keys; it does not send your API calls through our servers. Requires iCloud Keychain on each device that should share the same key secrets.
