The Browser Company, known for its Arc browser, has launched Dia Pro, an AI-powered web browser with a $20 per month subscription. Dia Pro offers unlimited access to the browser's AI chat feature, enabling users to ask questions about tab content. Free Dia users retain access to the original features, including the AI chatbot and custom skill creation. However, free users may encounter limits with frequent use of the AI chat. Specific limitations for non-subscribers have not been detailed, but CEO Josh Miller has stated that the browser will remain free for users who only occasionally use the AI tool.
