Your input.
Built into more.
Core turns what you know about your business into a working website — guided by one intelligent build agent powered by Anthropic and OpenAI, with a framework and build engine developed in house by Sitethreesixty.
A true intelligent build system, not a gimmick — no extra costs, no tokens to buy.
Answer a few questions
A guided survey and a short conversation — your trade, your area, your services, what you like, a logo if you have one. Around half an hour, and the more you give it, the better the result.
The AI Agent compiles your blueprint
Sitethreesixty's AI Agent — not a chatbot, but an agent that consults — takes your answers and compiles a blueprint for your site. Powered by the latest models from Anthropic and OpenAI. No templates — the blueprint is built from your answers alone.
The 12 West Platform builds your draft
The Sitethreesixty 12 West Platform turns that blueprint into a real, hand-quality first draft: fast, accessible, and found on Google. A genuine build engine — not a template picker or a drag-and-drop toy.

An AI website builder is a great choice if…
- you enjoy building websites
- you don't mind learning new software
- you're happy managing hosting and updates
If that's you, you may not need Arc.
Arc is a better fit if…
- you'd rather spend time running your business
- you want someone else handling the technical side
- you just want to request changes and get on with your day
If that's you, Arc was built for exactly this.
Both use AI to create websites quickly. The difference is simple: an AI website builder gives you the software; Arc gives you the finished website — and looks after it afterwards. Your website is created by the AI Agent, then you approve everything before it's published.
