Roblox introduces an AI chat filter that rewrites swears in real time

On 5 March 2026, Roblox announced a new AI-powered moderation feature that automatically rewrites profanity in player chat instead of blocking messages entirely. The update is rolling out across the platform and aims to keep conversations readable during gameplay while still enforcing community rules.

Previously, Roblox’s chat filter would replace inappropriate words or entire messages with strings of “####”. While this helped block offensive language, it often disrupted conversations and made it difficult for players to understand what someone was trying to say.

AI rewrites messages to keep conversations flowing

The new system, called real-time chat rephrasing, uses artificial intelligence to modify messages that contain profanity. Instead of hiding the message completely, the AI replaces the offensive wording with a more acceptable phrase while keeping the original intent.

For example, a message such as “Hurry TF up!” would previously appear as “####” in chat. With the new system, it may be automatically rewritten as “Hurry up!” so players can still understand the message.

Roblox says this approach helps maintain the flow of communication during gameplay, especially in multiplayer games where players often rely on chat to coordinate actions or share quick updates with teammates.

According to the company, when a message is rewritten, everyone in the chat will see a notification explaining that the text was rephrased to keep the conversation civil.

Moderation rules remain unchanged

Although the message is rewritten, Roblox emphasized that the moderation rules have not changed. A message that gets rephrased is still considered a violation of the platform’s profanity policies. Players who repeatedly attempt to use offensive language may still face moderation actions.

The AI system is part of a broader update to Roblox’s chat safety tools. The platform has also improved its filtering technology to better detect attempts to bypass moderation rules, including the use of leet speak, where letters are replaced with numbers or symbols.

Roblox said the improved system can also better detect attempts to share personal information in chat. Early testing showed a significant reduction in missed detections when users tried to share or request personal details.

Feature limited to certain chat environments

At launch, real-time chat rephrasing is available for in-experience chat between age-verified users within similar age groups. The system also supports all languages currently available through Roblox’s automatic translation tools.

The company said it developed the feature with feedback from its Teen Council to better reflect how younger users actually communicate online.
