Roblox Unveils AI Chat Filter for Safer Conversations
Roblox announced a real-time, AI-powered chat rephrasing feature that replaces banned words with respectful language instead of masking them with hash marks. The system reformulates filtered messages to preserve the original intent (for example, turning “Hurry TF up!” into “Hurry up!”) and notifies chat participants when a message has been rephrased. Roblox says the feature works across all languages supported by its automatic translation tools. The company also upgraded its text-filtering to better detect leetspeak and other bypass attempts, reporting a 20x reduction in false negatives for sharing or soliciting personal information. Roblox says traditional safety systems remain in place for more serious behavior.
Feature improves in-game chat quality and moderation on a major gaming platform, reducing disruption and lowering some moderation false negatives; relevant for platform safety and brand-safety considerations but not industry-shifting.

Key Takeaways & Evidence Grounding
- Roblox introduced a real-time, AI-powered chat rephrasing feature to replace banned words with more respectful language.
- The new rephrasing replaces prior behavior that showed banned text as hashes ("####") and notifies chat participants when a message is rephrased.
- Roblox reports the upgraded text-filtering better detects leetspeak and sophisticated bypass attempts, reducing false negatives for sharing/soliciting personal information by 20x.
- The rephrasing feature supports all languages available via Roblox’s automatic translation tools.
- Roblox states existing safety systems remain active for more serious behavior; the announcement follows prior moves including mandatory facial verification for chat access amid lawsuits over child safety.

Roblox launches AI game-creation mobile feature
Roblox unveiled Build, a mobile-first, AI-powered game-creation feature that generates playable game starting points from simple text prompts inside the Roblox app. Build uses a mix of open-source and proprietary Roblox AI models to produce gameplay mechanics, environments, characters, visuals and sound, and it shares back-end models, chat history, and projects with Roblox Studio so creators can move work between mobile and desktop. Public alpha begins July 28, 2026 in New Zealand for users aged nine and older; publishing and select features will require age verification with publishing limited to older users (16+). Roblox will surface AI-generated experiences based on player retention and maintain existing safety reviews. The company is also testing agentic AI tools for playtesting/analytics and developing foundation models for 3D asset and scene generation, a launch that has sparked debate over low-quality, repetitive AI games.
Roblox open-sources three safety models via ROOST
Roblox is contributing three open-source safety models — an updated PII Classifier, Roblox Sentinel, and a voice safety classifier (v3) — to the Robust Open Online Safety Tools (ROOST) Model Community. The PII Classifier's F1 score rose from 63.41 to 90.52 in version 2.0, and the expanded benchmark dataset now supports 189 languages (up from 17) and includes synthetic multiuser conversations to simulate evasion attempts. Roblox said Sentinel detected nearly 70% of its child-endangerment cases through early detection during the 12 months ended August 7, 2026. The voice safety classifier v3 supports 30 languages across eight violation categories and achieved 61% recall at a 1% false-positive rate. Roblox joined ROOST as a founding member alongside Google and OpenAI in early 2025.
Roblox adds agentic Planning, Mesh, and Procedural tools
Roblox announced upgrades to its plain-language AI tool, Roblox Assistant, introducing agentic features that help creators plan, build and test games inside Roblox Studio. Key additions include a collaborative "Planning Mode" that analyzes code and data models, asks clarifying questions, and produces editable action plans; Mesh Generation for quickly inserting fully textured 3D meshes; and Procedural Models for editable, code-driven 3D assets that adapt to scene relationships. The Assistant can run multi-step development workflows including automated playtesting (reading logs, capturing screenshots, simulating inputs, identifying bugs and applying fixes). Roblox said it is also building support for multiple parallel AI agents, long cloud workflows, and integrations with third-party tools such as Claude, Cursor and Codex.
