Roblox shares AI child-safety tools parents should know

If your child plays Roblox, chances are plenty of their friends do too. Roblox reported an average of 123 million daily active users during the second quarter of 2026. Nearly three-quarters of its age-checked users are under 18. With that kind of reach, one of the biggest risks a child can face may begin with a conversation that seems completely harmless. Someone asks what games they like. Later, that person wants to know where else they chat. Eventually, they suggest moving the conversation to another app. That progression should sound familiar to parents who have followed online grooming cases.

Earlier this year, we covered a disturbing involving two girls, ages 12 and 14. Investigators said a Nebraska man initially contacted them through Roblox before conversations moved to Snapchat. Authorities described the case as online grooming. Now Roblox is opening up some of the artificial intelligence it uses to detect behavior that can lead to dangerous situations.

On Aug. 19, Roblox announced that it is contributing updated versions of three safety models to the Robust Open Online Safety Tools, or ROOST, Model Community. The company is also releasing a new evaluation dataset so other platforms can test their own safety systems. For parents, the technical details matter less than what these tools are trying to catch. They focus on attempts to get personal information, signs of possible child endangerment and inappropriate behavior in voice chat. Here's how these new AI safety tools work, what they could mean for your child and what you can do right now to help keep your kids safer online.

Roblox already uses versions of these on its own platform. Now, other companies can study them and potentially adapt them for their own services. Roblox joined ROOST as a founding member in 2025 alongside Google, OpenAI, Discord and others. ROOST focuses on making open-source online safety technology available to organizations that may lack the resources to build sophisticated systems themselves.

Think about how many places children communicate online today. A conversation can begin inside a game. Then it may jump to a messaging app or another social platform with different protections. No single company controls that entire journey.

Sharing safety technology could give more services access to tools designed around similar warning signs. However, another company still has to adopt the technology and adapt it to its platform. So I see this as an encouraging development, but parents should not view it as a reason to lower their guard.

One of the most interesting updates for families involves Roblox's PII Classifier. PII stands for personally identifiable information. That can include a phone number, email address, social media username or other information that could help s
