Overview

Arcfield is a concept for a developer-tools company — brand, marketing site and docs system — with one twist that makes it AI-native: an agent living in the docs that drafts your integration code from a plain-English ask. Three days, end to end.

01 — The challengeWhat we were solving

Developer docs explain the API; they rarely get you to your first successful call. The gap between "reading the reference" and "it works in my codebase" is where most integrations stall — and where developers churn.

02 — The approachHow we built it

We built the identity and site fast with AI, then the differentiator: an agent embedded in the docs that takes "send a webhook when a payment succeeds" and returns working, copy-pasteable code for your stack — grounded in the live reference so it doesn't invent endpoints.
