How to Add Chat Overlay to OBS

Introduction to OBS and Chat Overlays

OBS (Open Broadcaster Software) is the go-to free software for live streaming and recording. A chat overlay allows you to display messages from your viewers directly on your stream so you can interact with them in real-time without switching tabs.

Why a Chat Overlay Matters for Streamers

A chat overlay keeps your audience engaged by showing them that their messages are being read. It also makes streams more interactive, especially for those watching on mobile or full-screen mode.

Understanding the Basics

What is OBS?

OBS is a free and open-source software that lets you capture your screen, use webcams, mix audio, and broadcast to platforms like Twitch, YouTube, and Facebook Gaming.

What is a Chat Overlay?

A chat overlay is a visual element added to your live stream showing real-time chat messages from your streaming platform.

Types of Chat Overlays

• Transparent Overlays – Blend seamlessly with your stream.

• Themed Overlays – Match your brand’s style.

• Minimalist Overlays – Keep the chat clean and distraction-free.
