Roblox is introducing a real-time, AI-powered chat rephrasing feature that automatically replaces banned words and phrases with more appropriate language, keeping conversations civil while reducing disruption. The company is also upgrading its text-filtering system to better detect attempts to bypass filters.

Why it matters

This new feature aims to improve the user experience on Roblox by maintaining community standards and civility in chat conversations, which are central to how people connect and play on the platform. It comes after Roblox faced lawsuits over child safety concerns, highlighting the need for robust content moderation tools.

The details

Instead of simply displaying hash marks when banned words are detected, the new rephrasing feature will replace the offending language with more respectful phrasing that is close to the user's original intent. For example, 'Hurry TF up!' would become 'Hurry up!' All users in the chat are notified that the message has been rephrased. Roblox says its safety system remains in effect for more serious violations.

  • Roblox announced the new feature on Thursday, March 5, 2026.
