Comet by Perplexity
AI browser for deep research and web exploration.
Comet is a strong pick if you're a heavy multi-source researcher who wants AI-assisted synthesis with auto-citations — it beats a standard browser for complex queries and complements tools like Perplexity's own search. The $20/mo Pro plan unlocks unlimited queries and priority access, which heavy users will need, but the free tier's 50-query daily cap feels tight. It's not for casual browsing or strict privacy environments, and the lack of mobile apps is a real gap. If you need a more portable or budget-friendly option, consider the free tier or a general browser with AI features.

Skip Comet if you need a mobile or desktop browser experience, require offline access, or expect to rely on the free tier for more than 50 AI queries a day.
Going past the free tier's 50 AI queries per day requires paying $20/month for Pro, which is a hard jump with no per-day top-up.
Comet's pricing fits individual researchers and small teams that need daily AI-assisted deep research. The $20/mo Pro tier is competitive with other AI research tools like Perplexity Pro or ChatGPT Plus, but heavy users may find it better value than per-query pricing. For casual users, the free tier is a good entry, but the daily cap makes it less suitable for all-day browsing.
In short
Comet by Perplexity — AI browser for deep research and web exploration. Best for Academic researchers, Journalists and analysts, Knowledge workers. Free to start; paid plans from $20/mo.

About Comet by Perplexity
Comet by Perplexity is a specialized AI-powered browser that streamlines deep research and web exploration for knowledge workers, researchers, students, and analysts. It combines a unified search interface with AI-generated insights, allowing you to ask follow-up questions, get multi-source analysis with automatic citations, and organize findings into collections. You can create custom AI agents for tailored research tasks, export data in multiple formats, and even automate multi-step workflows like booking flights or comparing prices. Available as a web app, Comet offers a free tier (50 AI queries per day) and a Pro tier at $20/month for unlimited queries and priority access. Unlike general-purpose browsers, Comet focuses on reducing manual fact-checking and accelerating complex research. However, it lacks mobile/desktop apps, requires an internet connection, and may struggle with heavy JavaScript sites. For deep research workflows, Comet is a strong alternative to traditional browsing, but casual users or those needing offline access should look elsewhere.
Behind the Verdict
Comet by Perplexity is positioned as an AI-first browser, not just another search tool. Its core promise is to reduce the friction in deep research by combining live web search with AI synthesis and automatic citations. This is genuinely useful for anyone who regularly juggles multiple tabs and sources to answer a complex question. The ability to ask follow-up questions in a conversational flow, create custom agents for repetitive research tasks, and organize findings into collections mirrors how a good research assistant works. The multi-step automation, such as booking flights or filling out forms, is a differentiator that most browsers don't offer, but it's also where the tool can be fragile. The free tier's 50 daily queries is generous for light use, but power users will quickly hit the ceiling. The $20/mo Pro tier removes that cap and adds priority access to advanced reasoning models, which is reasonable if you're using it daily for work. However, the lack of a mobile or desktop app is a significant gap for a tool that claims to be a browser — you're tied to a web app. Privacy-conscious users should also note that all queries go through Perplexity's servers, and there's no clear on-prem or self-host option. Overall, Comet shines for structured research tasks where synthesis and citations matter more than raw browsing speed. It's less ideal for casual browsing or sites with heavy JavaScript that might break the AI's interaction. If you're already in the Perplexity ecosystem, Comet feels like a natural extension; if you're not, the learning curve and the web-only limitation might give you pause.
