Our Verdict
Pick ChatGPT for one reason above all: Strong all-rounder for writing, coding, research, and analysis. Pick Perplexity instead if this matters more: Every answer links the sources it drew from. Both are freemium, so price is unlikely to decide it. The trade-offs are real on both sides, so weigh ChatGPT's limits against Perplexity's before committing.
