How many tabs do you have open right now?
Tabs are the ultimate multipurpose tool. We use them to work in applications, remind us of tasks we need to complete and gather information we might need later. Within each tab, a world.
Which is exactly why having too many tabs makes us so unproductive.
We’ve all been there. You’re in the flow of work and a notification pops up. You realize you’ve forgotten to check something important, so you open a new tab in your browser. But along the way, you see another abandoned task and start working on that instead. In less than a minute, you’ve completely lost track of what you were supposed to be doing.
Researchers have found the average knowledge worker toggles between desktop apps and browser tabs an average of 1,200 times a day. Each switch takes a few seconds of reorientation. By the end of the week, you’ve lost roughly four hours just getting your bearings. By the end of the year, you’ve lost five working weeks.
And that was before AI.
Knowledge workers are now managing AI agent outputs on top of everything else. Reviewing drafts and summaries. Verifying recommendations. Answering follow-up prompts. AI was supposed to take work off their plates. For many, it’s added a second helping.
Researchers have a name for what happens when this gets out of hand: AI brain fry, defined as the “mental fatigue from excessive use or oversight of AI tools beyond one’s cognitive capacity.” Workers in the study described a buzzing feeling, mental fog, difficulty focusing and even headaches. One commented, “It was like I had a dozen browser tabs open in my head, all fighting for attention.”
All of this information overload and task-switching comes at a real cost to the business. Workers experiencing AI brain fry reported 33% more decision fatigue and made mistakes with serious consequences more often, scoring 39% higher on major error frequency measures.
We mostly think of productivity as a personal problem, a reflection of poor focus and bad habits. According to UC Irvine’s Gloria Mark, a professor studying how devices affect attention for the last two decades, humans are wired to automatically respond to notifications flashing across our screens. However, Mark endorses that we can develop autonomy over our attentional resources; we’re not helpless to resist on-screen distractions. Controlling how we intake and process information in our digital environments can help significantly.
The researchers behind the brain fry study suggest that how workers access AI affects the amount of strain they experience. They noted that teams that integrate AI in their workflows and treat it as a capability (instead of a separate stack of agents to manage) experience lower cognitive burdens.
But most AI tools aren’t integrated. They sit in isolated tabs or desktop applications. Dozens of times a day, workers manually copy and paste or upload documents to their AI. They do the “gluing” their digital workspaces should do for them: surfacing relevant information, sharing context across apps, and embedding AI inside their workflows.
Most employees today use browsers as their primary digital workspace. And most of these browsers were not built for the enterprise, but for consumers to shop and search the Internet. AI providers like Google are investing heavily in backend integrations to connect their models with enterprise productivity apps and systems of record, when the context they really need — what the end user is doing — is right there in the browser.
To work productively, they need to see and plug in information from multiple sources at a glance. They need notifications that let them complete tasks without opening a new tab. They need AI woven into their entire workflow, not parked in an app they have to switch into and risk losing focus and making mistakes. The information users need lives in their digital workspaces. It just isn’t connected.
AI was supposed to give us our time back. But how much of that are we sacrificing to brain fry? More or less than the four hours a day, five weeks a year already lost to the toggle tax? A screen crowded with AI apps fighting for your attention doesn’t make anyone more productive.
Tech companies have spent the last few years building AI tools for every use case out there. It’s time to give users a more connected enterprise browser for accessing them productively.
