The best extension for research: comparing sources without losing your tabs

Real research — comparing sources, fact-checking a claim across a few outlets, reading around a topic before writing about it — has a shape that fights against how tabs normally work. You need several sources open at once, you need to compare them against each other, and you need to remember which one said what. A browser window full of identical-looking tabs actively works against all three.

What actually helps here

Feed view turns a page of search results into a scrollable column of full previews, so you can read five or six sources back to back without the page reflowing around you and without opening a single one of them into its own tab. For anything past the first page, Plus and up keeps loading as you scroll instead of stopping at the first ten results.

Split view goes further for genuine side-by-side comparison: pin up to four live pages next to each other with adjustable dividers, so you're actually looking at two sources at once instead of alt-tabbing between two tabs and trying to hold the first one's numbers in your head while you read the second.

Where AI fits into research, and where it shouldn't

Peekly AI can summarize a page or answer a direct question about it, and — on Pro — ask the same question to ChatGPT, Claude, Gemini, and Groq at once so you can see where they agree and where they don't, rather than trusting a single model's framing. It's useful for getting oriented fast. It's not a replacement for reading the primary source when the actual wording matters, and Peekly doesn't pretend otherwise — the summary sits next to the real page, not instead of it.

The actual point

None of this is about opening more tabs faster. It's about being able to hold several sources in view at once, compare them directly, and step back to your original list of results without losing your place — which is the part that normally makes real research feel more tedious than it needs to.
