AI
Your AI App Builder builds internal tools and client portals with AI builders and Supabase, then reviews the code for security.
Coding with an AI pair
GitHub Copilot, Cursor or Claude Code for boilerplate, refactors and first drafts. Every change is read and tested before merge.
Tests and edge cases
AI proposes test cases. Your AI App Builder runs them, fills the gaps and keeps the useful ones.
Docs and handover notes
READMEs, code comments and handover notes drafted with AI and checked against the code.
Debugging
AI helps read errors and logs. Your AI App Builder confirms the cause before changing anything.
Site copy and content
Page copy drafted from your brief, then checked for accuracy, SEO and accessibility.
Our rule: business-grade AI only, never free or personal accounts.
A person signs off before anything goes live, and builds run on your accounts, so you own what's built.
Tested before you meet them
