AI Browsers 2.0: Polar Aims to Revolutionize Knowledge Work

The latest iteration of AI browsers is focused on knowledge workers, with a startup called Polar launching an AI-first browser that automates tasks and workflows.

AI browsers were all the rage in 2025, with companies large and small trying to build browsers that baked in AI to own the interface people use to browse the internet. However, the focus has since shifted to agents and automation, with startups like Strawberry, Browser Use, and Aside building browsers with an agentic slant.

Polar's AI-first browser is designed specifically for knowledge workers, allowing them to schedule workflows, save prompts, and assign tasks to agents based on their open tabs. The company claims that its browser can be easily used by non-technical users and can help with work like sales, recruitment, marketing, research, and business operations.

CEO Kevin Jiang, who previously worked at Perplexity on Comet, explained that the first wave of AI browsers aimed to change default search for users and have them chat with tabs for doing tasks like travel booking, which wasn't a strong long-term proposition. Jiang noted that Polar's AI browser is not focused on mass consumers but rather on knowledge workers, where browser agents are actually valuable.

"If you think about end-user consumers, they don't book a flight or make a reservation every day or every week. There wasn't a strong pull for mass consumers to go to an AI browser and find value in it," Jiang said.

Polar has raised a $5.7 million seed round led by Madrona, with participation from ex-GitHub CEO Thomas Dohmke, Phia founder Phoebe Gates, Modal CEO Erik Bernhardsson, Flapping Airplanes co-founder Benjamin Spector, Etched co-founder Rob Wachen, and Fundamental Research Labs co-founder and CEO Robert Yang.

The browser itself is free to use, with users getting a few daily credits to spend on AI tasks. Users who want higher credit limits can pay for subscription plans starting from $20 per month. Polar's goal is to become a tool for automation, and it believes that the browser is currently the best way to do it.

"I think that the hard part is building really reliable agentic work on the open, logged-in web. Building a web browser has a whole set of different advantages of understanding how users interact and engage with websites. Plus, they are logged into most of these websites, giving the tool access to services they use the most," said Sabrina Albert, a partner at Madrona.

Polar's launch marks a new chapter in the evolution of AI browsers, with a focus on knowledge workers and automation. As the company continues to grow and develop, it will be interesting to see how it addresses the challenges of building reliable agentic work on the open web.
