It is an easy phrase to put on a website, so it is worth being specific about what we mean.
Every AI-generated change is read by an engineer before it merges. Not skimmed for whether it runs — read for whether it is correct, secure, accessible and maintainable. In practice, the recurring problems we catch are consistent: state handling that works in the happy path and breaks on a slow network; heading levels chosen by visual size rather than document structure; missing ARIA on custom interactive components; error handling that swallows failures silently; and dependencies added for a single utility function.
None of these break the demo. All of them cost you later, and none are visible to a client reviewing a staging link.
We also refactor rather than accept. Generated code tends toward repetition — five components that each solve the same problem slightly differently. Left alone, that becomes the thing that makes your site expensive to change in year two. Consolidating it is unglamorous work that AI is happy to help with once a human has decided what the right abstraction is.
The speed is real, and it is the reason we can build in weeks what used to take a quarter. But the review is what makes the speed worth having, and it is not optional on our projects.
