Perplexity starts with search, while ChatGPT starts with the task. Both can evaluate current web sources and produce longer answers.
When to pick which
Choose Perplexity when current search with visible sources is the starting point and you want advanced models from different providers in one research interface. Choose ChatGPT if you want ChatGPT Work to turn research into a Word report, Excel analysis, or slides, then add images, custom GPTs, or code changes with Codex. Perplexity no longer stops at the answer either: Computer can perform multi-step work across the web, files, code, and connected apps, while Projects retain files and working context across tasks. The difference is therefore one of emphasis: Perplexity puts source work and model choice at the center, while ChatGPT connects research more closely to its own production and development tools. Both free offerings have usage limits: Perplexity distinguishes basic search, Pro Search, and Research, while ChatGPT applies limits by model and tool. API costs are separate for both, and the calculator below compares only OpenAI and Perplexity.
