  • 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.
