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.

Sovereign AI models and autonomous coding agents for regulated, secure environments
A family of frontier LLMs trained on the UK's Isambard-AI supercomputer and specialised for UK and EU regulatory frameworks, legacy programming languages and mission-critical workflows, with 1T and 200B parameter variants announced.
Run Cosine fully air-gapped inside your own infrastructure, in a dedicated managed single-tenant environment, or through Cosine's managed public cloud—with data handling and access controls set by you.
Agent surfaces that cover terminal-driven engineering tasks, everyday desktop research and document work, and long-running parallel jobs in isolated cloud environments.
Designed for defence, government and critical national infrastructure teams that need frontier reasoning inside disconnected networks.
Powerful full-stack app generation from natural language, but offers more polished UI components and smoother deployment flows.
