iRun Studio vs ExpertAgent

iRun for iPadOS and iOS is a companion app for running AI locally and efficiently. Cloud providers are also available, but require api keys. iRun can run an AI model right on your iPhone, iPad or Mac. Built natively for apple silicon, iRun carries a tiny footprint, while compiling and optimizing AI models in realtime. This allows for large context windows and everyday usability, even on small devices such as phones. iRun is free to download and use (no token limits, full customization and privacy). iRun Pro enables access to many features, especially for the MacOS version. We are constantly updating the app and its functionality to enhance the user experience. Read our EULA here: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Stop starting every AI chat from zero. ExpertAgent is a native iPhone app that helps you build reusable AI experts — then paste them into ChatGPT, Claude, Gemini, or Perplexity as Custom Instructions, a system prompt, or your first message. It is not a chatbot. It is not another prompt generator. Define role, skills, and tone once, and start every chat already in context. Whether you are tired of generic answers, re-explaining your background, or inconsistent AI tone, ExpertAgent turns a quick 2-step setup into a reusable expert you control. KEY FEATURES • Expert Builder — A guided 2-step flow: pick your role, shape skills and tone, then generate. AI crafts a ready-to-paste system prompt from your inputs. • Use in ChatGPT, Claude, or Gemini — One tap opens your expert in the AI app you already use. Copy or share the full prompt anytime. • My Experts library — Save, search, edit, and organize experts on your device. When signed in, your library syncs for backup and cross-device access.
