Overview

Sigma Chat is an AI assistant embedded directly inside Sigma Browser. Instead of switching tabs to use tools like ChatGPT, you interact with AI while you browse—on any page.

It combines browsing and AI into one workflow. Think of it as a sidekick that reads, writes, and explains content in real time.

Most AI tools live in separate tabs. That slows you down. Sigma Chat removes that friction.

If you’re researching, writing, or learning online, it helps you:

Summarize long articles instantly
Ask questions about any webpage
Generate content without leaving your tab

It’s especially useful for students, researchers, marketers, and anyone who spends hours reading or writing online.
