They look similar — a box you ask questions — but they're built for different jobs. Perplexity is an answer engine optimized for sourced, up-to-date research. ChatGPT is a general assistant that writes, codes, reasons and creates.

Research & citations
Perplexity wins here decisively. Every answer is grounded in live web results with visible citations, so it's ideal for research, current events and fact-checking. ChatGPT can browse the web too, but Perplexity is purpose-built around sourced answers.
Everything else
ChatGPT is the broader tool: long-form writing, coding, data analysis, custom GPTs, image generation and deeper reasoning. If you want one assistant for creative and knowledge work, it's the more capable generalist.
Speed & style
Perplexity is fast and focused — question in, sourced answer out. ChatGPT is more conversational and flexible, better for iterating on a draft or thinking through a problem.

Honestly? Many people use both: Perplexity to find, ChatGPT to build. If you only pick one, choose by which you do more of. Also worth a look: Google Gemini. More in our Research category.
