What Is Sigma AI Browser?

Sigma AI Browser is a next-generation web browser engineered for the AI era — combining intelligent assistance, uncompromising privacy, blistering speed, and transparent pricing. At its core lies SigmaGPT, a purpose-built, on-device AI engine that powers real-time chat, content creation, webpage summarization, and contextual research — all without sending your data to remote servers.

Why Choose Sigma AI Browser?

Unlike traditional browsers with add-on AI extensions, Sigma integrates intelligence natively — delivering seamless performance, end-to-end encryption, and zero-tracking browsing. Its lightweight architecture ensures faster page loads, lower memory usage, and extended battery life — making it ideal for professionals, students, and privacy-conscious users alike.

Sigma AI Browser: Key Features at a Glance

  • AI Power: SigmaGPT responds instantly in-chat, drafts emails, explains complex topics, and transforms ideas into structured content — all within the browser window.
  • Privacy First: No telemetry, no ad profiling, no cloud-based AI inference by default. Optional cloud features (e.g., cross-device sync) are opt-in and fully encrypted.
  • Blazing Speed: Built on a modern Chromium fork with AI-optimized rendering — pages load up to 40% faster than standard browsers, especially on low-bandwidth or older hardware.
  • Transparent Pricing: Free tier includes full SigmaGPT access and core privacy tools. Pro plan ($4.99/month or $49/year) unlocks advanced AI workflows, priority support, and offline model caching.

FAQs

What makes Sigma AI Browser different from other AI browsers?

It’s the only mainstream browser that runs SigmaGPT locally by default — meaning your prompts, browsing context, and generated content never leave your device unless you explicitly choose otherwise. Combined with a lean, privacy-hardened codebase, it delivers true AI empowerment *without* surveillance.

Is Sigma AI Browser really free to use?

Yes — the core browser and full SigmaGPT functionality are completely free forever. The optional Pro tier enhances productivity with features like multi-step AI agents, custom prompt libraries, and encrypted cloud sync — but none are required to experience AI-powered browsing at its best.

Does Sigma AI Browser work offline?

The lightweight SigmaGPT Lite model runs entirely offline for basic tasks (chat, summarization, translation). For advanced reasoning or large-context generation, an internet connection enables optional cloud acceleration — always with clear user consent and encryption.
