Roblox offers an AI assistant built into Roblox Studio that helps game developers write code, plan experiences, generate 3D assets, and test games using plain-language prompts. The assistant, upgraded in April 2026 with agentic features including Planning Mode and automated playtesting, acts as a multi-step collaborative development partner for the platform's creator community.

The Assistant (previously anchored by Code Assist, which reached full general release in February 2024) accepts natural-language prompts and produces Luau script code, 3D mesh objects via the Cube 3D Mesh Generation API, and structured game-design action plans. The April 2026 'agentic' upgrade added Planning Mode—which analyzes a game's existing code and data model, asks clarifying questions, and generates an editable action plan—plus a playtesting agent that reads output logs, captures screenshots, and simulates keyboard/mouse inputs to identify bugs and feed corrections back into the planning loop. Roblox also announced integration of the Model Context Protocol (MCP) so creators can connect external tools like Claude, Cursor, and Codex with Studio.
