AI browsers or agentic browsers: a look at the future of web surfing

The article discusses a new generation of AI-powered or “agentic” browsers that embed AI agents directly into the browsing experience, acting as personal assistants rather than simply adding plugins. It highlights several examples, including the Dia browser, Fellou, Comet, Sigma browser, and Opera Neon, noting their focus on tasks such as summarising tabs, automating workflows, and protecting against distractions like tab overload.

It explains how these browsers differ from traditional ones by offering conversational interfaces, autonomous task execution, context awareness, built‑in privacy and security features, and integrated AI tools for generation and management. The piece also weighs safety and privacy concerns, mentioning end‑to‑end encryption in Sigma, the potential for bugs in early‑stage software, and the need to review privacy policies and data handling practices.

It suggests a cautious approach, recommending experimentation with AI browsers like Sigma or Comet while keeping a standard browser for day‑to‑day use, and notes that prompt injection research has shown attackers can target AI browsers. For those interested, Mind2Web is cited as a dataset for developing and evaluating generalist agents for the web, according to Mind2Web. Posted on 12 September 2025.
