Perplexity – AI Companion Review 2026: Cited Answers While You Browse

Perplexity’s AI Companion puts the answer engine’s cited answers into a browser toolbar, so you can summarize the page you’re reading or ask follow-up questions without opening a new tab. For anyone who already trusts Perplexity’s citation-heavy answers, the Companion is a natural shortcut. The free tier covers only a handful of cited answers per day, so heavy researchers will hit the ceiling quickly.

Bottom line: A genuinely useful shortcut for Perplexity fans: page summaries, page-specific questions, and cited answers right from the toolbar. Light users on the free tier get the most value; anyone doing daily research will likely need Pro.

Perplexity – AI Companion is a free browser add-on developed by Perplexity AI, designed as an “ask anything while you browse” layer on top of your normal reading. Instead of copying text into a chat window, you ask from the toolbar, get a concise answer with cited sources, and keep reading. The pitch is simple: combine the conversational feel of ChatGPT with the source transparency of a search engine, available on whatever page you happen to be on. It performs best on content-rich pages — articles, papers, Reddit threads, product listings — where there is enough material for the summarizer to work with.

Key features

Instant page summaries: One action summarizes the article or page you’re viewing, saving a scroll through long-form content.
Ask from the toolbar: Pose any question directly from the browser toolbar without navigating to the Perplexity site.
Page- and domain-aware questions: Ask questions about the current page or the site you’re on, with answers grounded in that context.
Cited sources on every answer: Answers come with source links, which is the feature that separates Perplexity from a standard chatbot.
Follow-up questions: Continue the thread with follow-ups from the same panel instead of starting over.
Shareable answers: Share an answer with a link, so someone else can see exactly what the AI produced.
Research helper workflows: Third-party guides highlight uses like content outlining, database searching, and reviewing Amazon product pages.

Who it’s for

The Companion fits students and researchers who fact-check as they read, writers who need fast summaries of source material, and comparison shoppers working through product pages. It’s also a low-friction way to try Perplexity’s approach before committing to a paid plan. If your browsing is mostly quick scans of news and articles, the free tier’s daily allowance may be all you ever need. People doing structured, multi-hour research sessions will outgrow the free limits fast and should weigh the Pro tier against simply using the main Perplexity site.

What to watch out for

The free plan’s daily allowance runs out quickly under real research use, and the strongest models stay behind the paywall. The Companion is a reading aid, not an agent — it answers and summarizes but doesn’t take actions on pages for you. Like any AI summarizer, it can miss nuance or misread a passage, so verify anything you plan to cite or act on. It requires an internet connection (it’s a cloud service), and it’s worth knowing this extension is a separate product from Perplexity’s free Comet browser, which bundles a sidebar assistant with full browsing — don’t confuse the two when comparing options.

Pricing

The extension itself is free to install. Perplexity’s plans: Free with a limited daily allowance of cited answers; Pro at $20/month ($17/month billed annually) for higher limits, advanced models, and file analysis; Max at $200/month for the heaviest usage. Pricing verified September 2026 — always check current pricing on perplexity.ai before paying, since the company adjusts tiers and limits.

Pros and cons

Pros

Citations on every answer make verification far easier than with a plain chatbot.
Works where you’re already reading — no tab-switching to an AI site.
Free to install and genuinely usable without paying for light, daily use.
Follow-up questions and shareable answer links fit collaborative research.
Best-in-class fit for content-rich pages like articles, papers, and forums.

Cons

Free tier’s daily usage limit is quickly exhausted by serious research sessions.
Strongest models and file analysis require the $20/month Pro plan.
Summaries can miss nuance; answers still need human review before use.
No agentic actions — it summarizes and answers but doesn’t act on pages.
Cloud-only; an internet connection is required at all times.

Frequently asked questions

Is the Perplexity AI Companion free?

Yes, the extension is free to install and the free Perplexity plan covers a limited number of cited answers per day. Heavier use, advanced models, and file uploads require Pro ($20/month, or $17/month billed annually).

Which browsers does the Perplexity AI Companion support?

It’s offered as a Chrome extension. Perplexity’s separate Comet browser (built on Chromium) is a different product that bundles an AI sidebar assistant with the browser itself.

Can the Companion summarize any webpage?

It works on most webpages but performs best on articles, research papers, Reddit posts, Amazon listings, and other content-rich sites, according to third-party usage guides.

How is it different from just using perplexity.ai?

The Companion brings the same cited-answer engine to whatever page you’re on — summaries, page-specific questions, and follow-ups from the toolbar — instead of requiring you to copy content into the Perplexity site.

Should I trust its answers for research?

The citations help, but Perplexity’s own materials position it as a research starting point. Open the cited sources and verify claims yourself, especially for anything you’ll publish or act on.
