Why RoCortex

A development partner, not a chatbot

It sees your project, writes code that fits, and puts it where it belongs.

Project-aware AI

Reads your full DataModel tree, scripts, and dependencies — then generates code that actually fits your game.

Instant sync

Code appears directly in Studio. No copy-paste, no file shuffling, no leaving your editor.

Smart edits

Surgical find-and-replace on existing scripts. It changes what you ask and preserves the rest.

Console mirror

Studio output streams to your browser. Say "fix that error" and the AI already sees it.

6 AI models

From 1-credit Flash for quick scripts to frontier models for complex systems. Pick per prompt.

Full undo

Every AI change is a ChangeHistory waypoint. Ctrl+Z reverts anything — safe to use on a live game.
