Best for

ChatGPT

Everyday writing, explaining, research and first drafts that you will edit yourself.

Perplexity

Looking things up: questions where you want an answer with links to the sources.

Strengths

ChatGPT

  • Conversation. Good at explaining a topic in plain language or turning rough notes into a structured draft.
  • Research. Deep research and file uploads help with longer questions. Check the sources it cites.
  • Extras. Custom GPTs, projects and scheduled tasks suit repeat jobs; the free plan limits them.

Perplexity

  • Sourced answers. Each answer links to the pages it used, which makes fact-checking faster.
  • Deep research. Longer research mode suits a topic you are new to.
  • Model choice. Paid plans let you pick the underlying model; the free plan is more limited.

Prices were checked on each vendor’s own pricing page on Oct 19, 2026. Plans change often, so confirm on the official site before you pay.

How to choose

  • Do you want every answer to link to its sources?

    Choose Perplexity

    Perplexity links each answer to the pages it used, which makes fact-checking faster. Open the link anyway: a cited answer can still misread its source.
