Sigma

Sigma란 무엇인가요?

Sigma is a private AI browser built around three main functions: browsing, AI chat, and an AI agent. The site presents it as a Chromium-based browser with local AI, privacy features, and built-in tools for everyday web work.

Its AI agent can act on web pages by navigating sites, filling forms, and managing tasks, while Sigma AI Chat handles questions, research, image generation, and text creation. Sigma also includes Eclipse, a local LLM that runs inside the browser so prompts and sensitive data stay on the device when using local AI features.
