ChatGPT vs Perplexity
These serve different primary purposes. Perplexity is built around citing its sources for research questions; ChatGPT is a broader general-purpose assistant. If your main need is "answer this with sources I can check," Perplexity is the more purpose-built choice.

You want a general-purpose assistant for writing, coding, brainstorming, and varied tasks beyond research.
