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.

Drowning in browser tabs? Web Canvas gives the web room to breathe. Instead of juggling tabs, create an infinite canvas where websites, images, and your own notes live together in your own visual workspace; pan, zoom, and connect everything you're researching in one place. WORKING CANVAS • Pan and zoom freely across your workspace • See all your research and browsing at a glance • Navigate spatially instead of linearly through tabs • Turn on a canvas grid to stay oriented as you pan and zoom • Recenter with one tap to snap back to where you started • Sessions: name, save, and reload your canvases; return to your research anytime • Share a saved session link; tap it to reopen that canvas on your device VISUAL BROWSING • Add multiple browser windows to your canvas • Images show in your workspace • Sticky notes: jot a thought right next to the site it belongs to • Connect any two items with a line to map how your research fits together • Color-code anything: give windows a color to group by theme, priority, or status • Arrange everything exactly how you think DESIGNED FOR RESEARCH & EXPLORATION Whether you're researching a project, planning a trip, or diving deep into a topic, Web Canvas lets you organize the web your way. Keep related websites close together, leave yourself a note about why something matters, create visual clusters of information, and never lose track of that one tab again. NATURAL GESTURES • Drag windows anywhere on the canvas • Pinch to zoom in and out • Pan with one finger to navigate and the canvas glides to a smooth stop • Two-finger trackpad swipe to pan on iPad • Full-screen mode for focused reading • Read Mode / Lock: follow links in place without new windows POWERFUL FEATURES • Share a URL from another app and open it on your canvas in one step • Full web browsing and your favorite search engines • Search history that remembers your journey • Dark mode support • Optimized for both iPhone and iPad • Smooth 60fps animations MAKE IT YOURS • Pin and reorder the toolbar buttons you use most • Choose your primary color and theme • Pick your default search engine • Start of RTL handling and translations Perfect for: • Research projects and deep dives • Visual learners and thinkers • Anyone drowning in browser tabs • Students organizing study materials • Designers collecting inspiration • Writers gathering references Your research deserves more than a list of tabs. Give it space to breathe.

Verdict
The clearest difference is in-app purchases: Web Canvas at none against Sigma Domain's 2. Sigma Domain's advantage is update cadence (every 5 days vs every 2 months). On price, ads, device support and iOS requirement there is nothing between them.
