See how one small fix grows into a system.

We take one page — a trading dashboard — and walk it through eight steps: from spotting something that does not work for you, through AI script creation, validation, live execution, agent use, consent, and publishing to the marketplace.

The eight steps

1. You spot something on a page that does not work for you.
2. You describe the change in plain language to the Customaise editor.
3. Customaise writes a reversible UserScript and shows you the diff with syntax highlighting and version history.
4. You see it run on the live page; flip the switch, the page breathes.
5. Each small fix stacks. The page becomes the page you wanted in the first place.
6. When chat is not enough, you open your IDE. The MCP bridge exposes your authenticated browser session to Cursor, Claude Code, Codex, and other MCP-speaking clients.
7. You give your AI new tools on the site by building an AgentScript. Typed, consent-gated tools the agent calls through navigator.modelContext.
8. You publish to the marketplace. Allow / prompt / deny consent on every tool. Every listing is reviewed before going live.

The full walkthrough on the How-it-works page covers each step with screenshots, code samples, and verify-yourself commands.
