Former Perplexity Engineer Launches Polar AI Browser to Automate Knowledge Work

Former Perplexity Employee Builds AI-First Browser Startup

Kevin Jiang, a former Perplexity employee who worked on Perplexity Comet, has launched Polar, an AI-first browser startup designed specifically for knowledge workers 1

. The company secured $5.7 million in seed funding led by Madrona, with participation from notable investors including ex-GitHub CEO Thomas Dohmke, Phia founder Phoebe Gates, Modal CEO Erik Bernhardsson, and others 1

. The launch signals a significant shift in how AI browsers are positioning themselves in the market.

Why Polar AI Browser Focuses on Knowledge Work Over Consumer Tasks

Jiang's strategy with the Polar AI browser deliberately avoids the mistakes of first-generation AI browsers that tried to replace default search engines or help with occasional consumer tasks like booking flights. "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 explained 1

. Instead, Polar targets professionals who perform repetitive tasks across multiple browser tabs daily, focusing on areas where browser agents deliver tangible value. The AI browser enables users to schedule workflows, save prompts, and assign tasks to AI agents based on their open tabs 1

Browser Agents Drive AI-Driven Browser Automation

The Polar AI browser is designed to automate repetitive tasks for knowledge workers across sales, recruitment, marketing, research, and business operations 1

. Built for non-technical users, the browser eliminates the need to write scripts or build custom automation solutions . The company operates on a freemium model, offering users daily credits to spend on AI tasks, with subscription plans starting at $20 per month for higher credit limits 1

. Most current users launch Polar specifically for automation while maintaining another browser as their daily driver 1

Market Shift From Search to Automation

The AI browser landscape has transformed dramatically since 2025, when companies competed to build browsers with integrated chatbots. OpenAI Atlas has disappeared, The Browser Company sold to Atlassian with its Dia browser now focusing on productivity, and startups like Strawberry, Browser Use, and Aside are building browsers with an agentic approach 1

. Even Perplexity Comet has shifted toward providing browser agents 1

1

. Sabrina Albert, a partner at Madrona, emphasized that automating tasks for knowledge workers represents a massive market opportunity. "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," she noted 1

What's Next for Polar

While Polar currently positions itself as a browser-based automation tool, the startup remains open to exploring other avenues such as computer use 1

1

. The company's immediate goal is to establish itself as the go-to automation platform for professionals, believing the browser format currently offers the best environment for this work. Polar must still prove that professionals will adopt a dedicated second browser for automation, but if AI browsing's next chapter centers on software that quietly completes work in the background rather than conversational search, the timing appears strategic 2
