About Perplexity Companion
Perplexity Companion is a browser extension that lets you ask questions about the current tab or any selected text using Perplexity's AI search engine.
Its edge is staying in-page: you can query the open tab or highlight text and get an answer without leaving the page, and it runs as a lightweight extension rather than a separate desktop or mobile app.
That in-browser scope is also its ceiling — it's an extension only, with no standalone app, and free-tier use is subject to Perplexity's standard query and feature limits. It fits people who want quick answers about what they're already reading in the browser.
Among browser extensions, it puts Perplexity's search directly on top of your current page, rather than sending you to a separate search interface.
