Google put Gemini inside Chrome. Microsoft put Copilot inside Edge. Apple built Apple Intelligence into Safari. None of these are extensions you install — they ship baked into the browser, and none of them follow you if you open a different one.
Somehow this is being sold as progress.
The “Agentic Web” Pitch, and the Part Nobody’s Advertising
At Google I/O 2026, Google laid out its vision for what it called the agentic web: an AI that reads the page you’re on, summarizes it, answers questions, and — with permission — takes actions like filling out forms or comparing products across open tabs. Edge’s Copilot sidebar does something similar for Microsoft 365 workflows, with tighter integration into work documents and calendars than Gemini offers in Chrome. Safari’s Apple Intelligence takes a different approach entirely, trying to keep as much processing as possible on-device before anything reaches Apple’s servers, which trades some capability for a genuinely different privacy posture than either competitor.
What none of the keynote slides mention is that these features are exclusive to their home browser. A 2026 roundup of browser trends put it plainly: these AI assistants are tightly coupled to the browser they ship in, and that pairing doesn’t loosen — it’s a permanent feature of how each company is building its AI story, not a temporary rollout gap.
People Are Already Splitting Their Browsing by Assistant, Not by Habit
The predictable result: open Edge for the work doc that needs Copilot, switch to Chrome to keep researching the same topic later, open Safari on a phone for something quick. Nobody planned this. It’s just what happens when three companies each decide their AI is the reason to stay in their browser.
It would be a mildly annoying inconvenience if it weren’t for the thing that quietly breaks every time: bookmarks. Save something in Edge while Copilot’s helping with a work task, and it’s nowhere to be found three hours later when Chrome is open for the personal version of the same research.
The Fix Nobody’s AI Roadmap Includes
None of Gemini, Copilot, or Apple Intelligence are going to solve this, because solving it would mean building a feature that works in a competitor’s browser. That’s not happening. Each company’s AI roadmap is explicitly designed to deepen loyalty to its own browser, not reduce the friction of using more than one — a cross-browser save feature would actively work against that goal, which is exactly why the ability to share a bookmark folder chrome, Edge, and Firefox all recognize the same way has to come from outside any single vendor’s roadmap.
As long as AI assistants stay locked to their home browsers — and there’s no sign that’s changing — the number of people quietly running two or three browsers a day is only going up. Bookmark portability stops being a nice-to-have the moment that becomes normal.
