Perplexity
AI answer engine with cited search, Comet browser, and autonomous Computer agent
Best for
Perplexity is an AI-powered answer engine that searches the web in real time and delivers cited, synthesized answers instead of a list of links. Built on multiple LLMs including GPT-4o, Claude, and its own Sonar models, Perplexity handles everything from quick factual lookups to deep multi-step research.
Pro users ($20/mo) get advanced model access, file uploads, image generation, and Focus modes for targeting specific source types.
In 2026, Perplexity expanded significantly beyond search. Perplexity Computer (Feb 2026) is a full agentic AI system on the $200/mo Max plan that orchestrates 19+ AI models, spawns sub-agents, and runs autonomous multi-step workflows that persist for hours or days even after you close the browser.
Perplexity Comet (March 2026) is a standalone AI-powered web browser available free on iOS, Android, Windows, and Mac, featuring a built-in AI assistant, voice mode, hybrid search, and Deep Research that works alongside your browsing. Spaces enables collaborative research where teams share and build on findings together.
Pros
- Real-time web search with citations: Every answer includes inline source citations you can verify instantly
- Comet AI Browser (2026): Free standalone browser on iOS, Android, Windows, Mac with built-in AI assistant, voice mode, hybrid search, and Deep Research
- Perplexity Computer: Agentic AI system that orchestrates 19+ models, spawns sub-agents, and runs autonomous multi-step workflows (Max plan)
- Spaces for collaboration: Team research workspaces where multiple users share findings and maintain persistent research threads
- Focus modes: Target specific source types: Academic, YouTube, Reddit, News, or Web
- Multi-model access: Uses GPT-4o, Claude, and Sonar models; Model Council compares outputs side-by-side
- Sonar API for developers: Build search-augmented AI apps with Sonar (from $1/M tokens) and Sonar Pro ($3/M input, $15/M output)
- Clean, ad-free interface: Focused experience without the visual clutter of traditional search engines
Cons
- Max plan is expensive: Perplexity Computer requires the $200/mo Max subscription
- Pro Search limits reduced: Pro searches cut from ~600/week to ~200/week; Deep Research capped at 20/month
- API credits are minimal on Pro: Pro subscribers only get $5/month in API credits
- Can surface inaccurate sources: Citations add transparency but AI can still misinterpret sources
- Comet browser is new: March 2026 launch, still maturing compared to Chrome or Arc
- Enterprise pricing is high: Enterprise Pro at $40/seat/mo and Enterprise Max at $325/seat/mo
Our Verdict
Perplexity has evolved from an AI search engine into a full AI platform spanning search, browsing, and autonomous agents. The core search with citations remains best-in-class for research-heavy work where source verification matters.
The 2026 additions change the value proposition significantly. Comet browser (free) makes AI-assisted browsing accessible to everyone, while Perplexity Computer (Max plan, $200/mo) pushes into agentic territory. Spaces adds genuine collaboration missing from most AI search tools.
At $20/mo for Pro, Perplexity works best alongside a general-purpose AI like Claude or GPT for creation and coding tasks. The free plan and Comet browser are genuinely useful for casual research. For power users who need autonomous workflows, the $200/mo Max plan is worth evaluating against dedicated agent platforms.
