The Browser Company — the makers of the Arc browser — just launched a $20 per month subscription to its new AI-powered web browser, Dia, as reported earlier by TechCrunch. The new Dia Pro subscription comes with unlimited access to the browser’s chat feature, which lets you ask questions about the content in your tabs.

People who use Dia for free will still have access to the same features the browser launched with, including the ability to interact with the browser’s AI chatbot and create custom skills. But free users might run into some limits if they frequently use Dia’s AI chat feature.

The Browser Company hasn’t carved out specific limits for non-subscribers, but CEO Josh Miller told The New York Times last month that “the browser will remain free for those who use the A.I. tool only a few times a week.” Miller also hinted at rolling out additional subscription tiers, ranging from $5 to hundreds of dollars per month.
