Sigma Private AI Browser

About the startup

Sigma Browser is a privacy-first AI browser built for people who want AI capabilities directly inside their everyday browsing workflow. It combines a built-in AI agent, AI chat, deep research, page summaries, image generation, and local AI in one Chromium-based browser. The AI agent can navigate websites, fill forms, and handle multi-step web tasks, while Sigma’s Eclipse local AI lets you run AI directly on your device without sending prompts to the cloud. Sigma also includes built-in ad blocking, encrypted private profiles, phishing protection, extension support, and tools such as Chat with Page and Quick Translate. It’s designed for developers, founders, freelancers, content creators, researchers, AI power users, and privacy-conscious users who want to browse, research, create, and automate from one place. Available for macOS, Windows, and iOS, with Android support on the way.
