Perplexity vs. ChatGPT: Research or a versatile work assistant?
Perplexity is a natural starting point if finding and checking web sources is your main task. ChatGPT fits well if you want to follow research with writing, file analysis and revision. Their capabilities now overlap considerably: ChatGPT researches with sources, and Perplexity also creates files and apps. A second subscription is only worthwhile if it fills a recurring gap.

Questions before choosing
Can ChatGPT replace Perplexity?
ChatGPT Search or Deep Research may be enough for many research tasks. Comparing them on real tasks will show whether Perplexity's search workflow offers you more value.
Is Perplexity just a search engine?
Its search focus remains important, but the current offering also includes research and the creation of files and apps.
Are answers with sources automatically correct?
No. Sources may be outdated or may not support the cited statement. Check the key passages.
Do I need paid subscriptions to both?
Only if you regularly need both for different requirements. First check your existing access and the free alternative.
Why does the SME score alone not decide this comparison?
The score assesses overall value. A lower-rated tool may be a better fit for a specialised research workflow.
