Sigma AI Browser alternatives

Sigma AI Browser is a full browser that combines AI chat, research, translation, a browser agent, a local offline model, and built-in privacy features. Most of these alternatives are browser extensions or web apps rather than replacements for the browser itself, so start by deciding whether you need a complete browser or an add-on. Then compare platform support, whether you want an agent that acts on pages, and whether a paid plan or your own API key fits your budget.
