Perplexity Review
A cited, source-linked research assistant instead of a plain chat response
Overview
Perplexity positions itself as a research-first AI assistant: every answer comes cited and source-linked, and a single Pro subscription lets users select between multiple underlying models rather than committing to one vendor. Its Comet browser extends the same assistant into agentic, multi-step web tasks. It's noticeably weaker than Claude or ChatGPT at open-ended creative and coding work, and its brand reach still trails the two market leaders.
Who It's For
Researchers, analysts, and anyone who wants a cited, source-linked answer instead of an uncited generated response.
Who Should Pass
Users prioritizing raw coding or creative-writing quality over citation and sourcing should default to Claude or ChatGPT instead.
Key Features
- Best for research questions that need cited, source-linked answers instead of an uncited wall of generated text
- Best for users who want to pick between underlying models (GPT, Claude, Gemini) inside one Pro subscription rather than juggling separate accounts
- Best for agentic web tasks via the Comet browser, which handles multi-step research, bookings, and shopping beyond a simple chat window

Pros & Cons
What Works
- Answers are cited and source-linked by default, a real differentiator from the more static, uncited responses of ChatGPT and Claude
- One Pro subscription includes selectable access to multiple underlying models instead of locking users to a single vendor's model
- The Comet browser extends the same assistant into agentic, multi-step web tasks rather than staying confined to a chat window
What Doesn't
- Noticeably weaker than Claude and ChatGPT at open-ended creative writing and coding tasks in side-by-side comparisons
- Brand awareness and market share trail ChatGPT and Gemini by a wide margin, which shows up as a smaller G2 review base
- The Max tier jumps to $200/mo, a steep step up from Pro for teams that outgrow the standard plan

Final Verdict
Perplexity is the clear pick for research-heavy work that needs citations, not just an answer — the Comet browser is a genuine extra for anyone who wants that same assistant handling multi-step tasks, not just chat.
