Sigma Domain vs PA Node

Sigma Domain is the AI workspace where you bring the tools — and the AI does the work. The conversation is powered by Claude, the model family behind the world's best coding and agent systems. When you want a sanity check, tap the brain button and get a second opinion from a catalog of 70+ leading models — OpenAI, Meta, Mistral, DeepSeek, Amazon, and more — with a summary of where they agree or differ. YOUR AI TOUR GUIDE Going somewhere? Start a tour and Sigma Domain narrates the places you pass — the history, the architecture, the stories — spoken aloud while you drive or walk. Road trips, neighborhood walks, museum visits: it's like a private radio station about wherever you are. POST YOUR OWN TOOLS Most AI apps are just chat. Sigma Domain includes a marketplace of thousands of ready-to-use tools — and you can register your own functions, APIs, and integrations, public or private. Your tools become part of the AI's toolkit, callable in plain English by you, your team, or anyone you share them with. LIVE MAPS YOU BUILD TOGETHER Search properties and places, pin and compare them on a shared map, vote with your team, and generate reports — commute times included. SKILLS Expert playbooks the AI loads on demand: create and edit Word documents, PowerPoint decks, Excel spreadsheets, PDFs, and more — so answers become finished documents, not just text. AI JOBS Hand off multi-step work. The AI plans the steps, calls the right tools, and reports back when it's done.

PA Node connects your iPhone to a user-configured personal agent system, such as OpenClaw. A desktop or server agent can do a lot on its own, but some workflows only work well when the phone is part of the loop. PA Node lets your agent use phone-native capabilities like push notifications, location context, and commute-aware actions, with permissions controlled by iOS. After setup, your iPhone is registered as a trusted device using a backend-issued credential. You can receive proactive notifications, share location context when enabled, and support workflows that are not possible from a Mac mini or desktop agent alone. Features include: • Secure device setup with a backend-issued credential • Push notifications from your configured PA server • Optional location sharing for commute and phone-context workflows • Commute job status, route choice, and refresh controls • In-app setup prompts for configuring your desktop or client agent • Privacy and support information built into Settings PA Node is built for people running their own personal agent infrastructure who want the iPhone to act as a secure, permissioned extension of that system.
