Perplexity
AI search and agentic research with cited sources
- Overview
- Perplexity started as an AI answer engine that replaced traditional search with real-time, cited responses, and has since expanded into a broader research platform. Its Computer product runs multi-step agentic workflows across 20+ models, Deep Research generates structured reports, and the Comet browser brings an AI assistant to every web page. Pro Search, focus modes, and a Sonar API remain available for developers.
- Why it matters
- Perplexity has become the clearest challenger to both traditional search and general-purpose LLM chat, combining live retrieval with citation transparency that enterprise users increasingly require for auditability. The 2026 expansion into Computer and Comet signals a bet on becoming a full research OS rather than a single-purpose tool—a positioning shift worth watching as it adds agentic lock-in risk alongside genuine workflow value. The steep jump from Pro ($20/mo) to Max ($200/mo) with no middle tier means teams may end up paying enterprise rates sooner than expected. Samsung's OS-level integration on the Galaxy S26 gives it a meaningful mobile distribution advantage over pure-chat competitors.
- In practice
- Research and RevOps teams use Perplexity Pro for daily sourced fact-checking, competitive monitoring via scheduled searches, and Deep Research reports that output directly to presentations or spreadsheets—replacing ad-hoc Google + ChatGPT workflows. Computer's email interface (cc computer@perplexity.com) lets teams kick off multi-step research tasks without leaving their inbox, and the Microsoft 365 integration brings it into Word and Excel. The honest limitation: answer quality depends heavily on what Perplexity's crawler can index, so paywalled or proprietary sources are silently absent from citations—a meaningful gap for legal, medical, or primary-market research.

Know the terms
Glossary entries that explain what Perplexity is built on.
RAG (Retrieval-Augmented Generation)
A technique that retrieves relevant documents from an external knowledge base and feeds them to a model alongside the user's query. RAG reduces hallucination and keeps responses grounded in current, factual data.
Grounding
Techniques that anchor AI outputs in verifiable facts by connecting models to external knowledge sources. Grounding reduces hallucination and is essential for enterprise use cases where accuracy is non-negotiable.
Hallucination
When an AI model generates confident-sounding but factually incorrect or fabricated information. Hallucination is the number-one barrier to enterprise AI adoption and a major focus of current research.
Agentic workflow
A multi-step process where an AI agent plans, executes, evaluates, and iterates on tasks with minimal human intervention. Unlike single-turn prompts, agentic workflows involve loops, branching logic, and tool calls that unfold over minutes or hours.
Models behind it
The models Perplexity runs on, offers, or competes with.
