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.

To get cited by ChatGPT and Perplexity, be the clearest answer in several places at once. Publish answer-first pages with extractable facts, get listed on directories and review sites the engines crawl, and build consistent mentions across Reddit, YouTube, and your own site. Perplexity tends to favour recent content; ChatGPT appears to weight agreement across sources.

If you built something with AI, posting is getting hard to ignore. GaryVee's 'interest media' shift is real — more feeds now recommend content by interest, not only by who follows you — so a maker with zero followers can sometimes out-reach an established brand. That's the unlock and the mandate: building got faster, getting seen is the job, and many products struggle to grow without it. Here's the honest first move, written for a builder who would rather ship a feature than post.
