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. WHY SIGMA DOMAIN - Powered by Claude for the main conversation — the engine behind today's best AI agents - Second opinions from 70+ models with one tap - A tool marketplace you can add to — publish your own tools in minutes - GPS-aware audio tours, live shared maps, document skills, and automated jobs - Natural conversation — no prompt engineering required Bring your tools.

Stop guessing which AI tools are good. Agentix grades any agent or tool S-F in seconds — then tracks momentum so you know who's rising and who's slipping. Search an agent, get an instant score broken down across 5 pillars, and watch its grade momentum rise or fall over time. WHAT YOU CAN DO • Grade any AI agent or tool and get a single S–F letter grade in seconds • See the score broken down by pillar — acceleration, traction, app & team credibility, and niche position — each with a plain-English rationale • Compare an agent head-to-head against the top 2 rivals in its space • Build a watchlist and track each agent's momentum (up or down) as it improves or slips • Call an agent's trajectory in play-money paper mode — go long or short and follow your P&L (no real money, ever) WHY AGENTIX Every other AI directory just lists thousands of tools and leaves you to guess. Agentix grades them. The score is forward-looking, transparent, and hard to fake — built to tell you not just what an agent is, but whether it is getting better or worse. WHO IT IS FOR Builders, investors, and curious users who want to evaluate AI agents before they trust them — and keep tracking the ones that matter. Agentix is free — no account, no sign-up. Grade as many agents as you like and keep your full history. Built by Jason Colapietro, founder of Suede Labs — building ownership infrastructure for the AI era. Grades are informational and are not financial advice. Paper mode uses play money only.
