Quick decision guide
Use these notes to shortlist the plan that fits your actual workflow.
Choose Perplexity when citations matter
Perplexity is the clearer fit when you need visible sources, quick source discovery, and answers that point back to the web.
Choose ChatGPT for broad assistant work
ChatGPT is more flexible when the work includes brainstorming, drafting, coding help, image tasks, file analysis, and back-and-forth iteration.
Use both only for distinct jobs
A two-plan setup can make sense if research and general assistant work are both frequent. Otherwise, start with the product that matches your most repeated task.
