AI-Enhanced Chat Moderation
Stop harmful content before users see it. AI-powered chat moderation built into PubNub—no code, no lag.
Built-in AI moderation runs inline to protect the experience, not just the screen.
Why it matters
When toxic content reaches users, trust erodes and teams scramble to recover.
Malicious content breaks trust
Toxic content breaks trust. Users leave. Teams scramble. Moderators burn out.
Most tools are too late or too slow
They react after the damage is done or rely on external APIs that introduce lag and risk.
PubNub stops it before it spreads
Built-in filtering intercepts harmful messages in real time, before they reach anyone’s screen.
You Can’t Moderate at Scale by Hand
Toxic messages slip through.
Human moderators burn out.
External APIs introduce lag
and compliance risk.
You need a native, real-time solution that protects your users and scales with your product.

How does it work with my stack?
PubNub Chat Moderation runs natively within your existing PubNub-powered app—no extra infrastructure or third-party APIs required. You can activate moderation directly in the PubNub UI, and if you need custom rules, simply extend the logic using PubNub Functions. This means you get seamless integration, whether you’re building in JavaScript, Unity, Python, or any other supported language.
What’s the latency impact?
The moderation engine is designed for real-time performance, processing messages inline with sub-500ms end-to-end latency. Your users won’t notice any lag—messages are filtered and delivered instantly, so conversations stay fast and natural.
Is data sent to third parties?
No. All moderation happens inside your dedicated PubNub Virtual Private Cloud (VPC) by default. Your chat data never leaves the PubNub environment, so you maintain full control and privacy—no external data sharing or exposure to third-party services.
Can we customize rules?
Absolutely. You can start with built-in moderation presets for common scenarios, then fine-tune or extend them using PubNub Functions. This lets you create custom filters, triggers, and workflows tailored to your community’s needs—all without managing extra servers.
Do I need to run servers?
No servers required. PubNub Chat Moderation is fully managed and serverless, so you don’t have to worry about hosting, scaling, or maintenance. Just enable the feature and focus on your users.
How do I try it?
Getting started is simple: log in to your PubNub account and enable Chat Moderation in the BizOps Workspace. There’s a generous free tier for developers, so you can test moderation in your app right away—no credit card or long setup process needed.
