Sigma AI Browser (formerly Bagoodex)
Sigma AI Browser is a Chromium-based private browser with built-in AI chat, search, and agents. Bagoodex merged into Sigma in 2025, and Bagoodex.io now shows a short landing page that sends visitors to Sigma AI Chat at app.sigmabrowser.com. Inside the browser you get Eclipse, a local large language model that runs on your device, plus cloud chat for deep research, image generation, and page-level Q&A.
Unlike AI search sidecars such as Perplexity Comet or ChatGPT Atlas that add a chat panel to browsing, Sigma ships as a full browser fork with local LLM processing, Web3 wallet hooks, and an agent that can click through sites on your behalf. Sigma publishes Speedometer 3.0 benchmark results on its homepage, claiming roughly 1.13x faster scores than Chrome and lower RAM use with ten identical tabs (0.8 GB vs 1.00 GB for Chrome in its comparison table).
Private Profiles split work and personal sessions behind a 12-word recovery phrase, and a built-in ad blocker plus phishing warnings target people who want privacy defaults without juggling extensions. Desktop builds cover macOS and Windows, with iOS and Android apps available and a Linux release listed as coming soon.
