Sigma Domain is the AI workspace where you bring the tools โ€” 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 โ€” OpenAI, Meta, Mistral, DeepSeek, Amazon, and more โ€” 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 โ€” the history, the architecture, the stories โ€” 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 โ€” 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 โ€” commute times included. SKILLS Expert playbooks the AI loads on demand: create and edit Word documents, PowerPoint decks, Excel spreadsheets, PDFs, and more โ€” 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. WHY SIGMA DOMAIN - Powered by Claude for the main conversation โ€” the engine behind today's best AI agents - Second opinions from 70+ models with one tap - A tool marketplace you can add to โ€” publish your own tools in minutes - GPS-aware audio tours, live shared maps, document skills, and automated jobs - Natural conversation โ€” no prompt engineering required Bring your tools. Ask for outcomes. Sigma Domain does the rest. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

About

Decubed

Read full description

Decubed is the local-first AI workspace for the models, tools, memory, and agent workflows you choose. Most AI apps start with one model. Decubed starts with your environment. It gives you one place to connect model providers, work with local or remote model paths, keep durable threads, manage memories, and control which tools an agent can use. Use Decubed to: - Bring local, remote, linked-account, and custom models into one workspace. - Keep threads, folders, memory, tools, approvals, and run history attached to your environment. - Approve sensitive tool actions before they run. - Inspect tool calls, waiting states, and completed runs in the thread. - Configure agents around jobs with their own model, prompt, tools, skills, and memory policy. Decubed is designed for people who want model choice without giving up context or control. Run supported models on device when work should stay close to you, or connect hosted providers when a task needs remote capability. Bring the model. Keep the control.
