Which one wins for which use case
For most people's default "ask a question" habit, ChatGPT's scale and brand recognition make it the path of least resistance. For research-heavy work where sourcing matters — competitive analysis, fact-checking, literature review — Perplexity's citation-first design is built specifically for that job, and its growth rate suggests a meaningful and expanding user base values that trade-off.

Frequently asked questions
Yes, in percentage terms — Perplexity's traffic grew roughly 200% year-over-year, well above ChatGPT's growth rate. But ChatGPT's absolute user base (about 1 billion vs Perplexity's ~30 million) is so much larger that Perplexity's faster growth hasn't meaningfully closed the market-share gap yet.
ChatGPT functions as a general-purpose assistant across writing, coding, and conversation. Perplexity is built specifically around search and citation-heavy research, which is why its usage skews toward people who want sourced answers rather than open-ended conversation.
