Build working apps, websites, and AI agents by describing them
Describe an idea and get a working app with database, authentication, payments, and hosting already wired up — no server or infrastructure setup.
Generates complete websites with layout, copy, and design, plus built-in SEO tools and custom domain support, ready to publish in one click.
Create 24/7 AI agents that connect to your tools, take real actions, manage data, and automate recurring workflows autonomously.
Connects to Google Calendar, Gmail, Slack, Notion, HubSpot, Salesforce, and more, with API access for anything else you use.

Autonomous web businesses, cast by invitation and run by an AI swarm
Each engagement is cast around one owner's vision and business rather than assembled from a shared template library.
Strategy, research, writing, design, building, publishing, optimisation and analytics are handled by dedicated AI agent roles working in parallel.
Content is structured with Schema.org markup - FAQ, article, event, local business and product - so answer engines can cite your site as the source.
Auto-updated XML sitemaps, per-page OG images, RSS/Atom feeds, a PWA manifest and inlined critical CSS ship with every site.
