Frequently asked questions
Is Perplexity better than ChatGPT for research?
Yes, for most research tasks. Perplexity retrieves real-time web sources and cites every claim, which is essential for research where accuracy and currency matter. ChatGPT without web browsing is limited to its training cutoff and has no citations.
Does Perplexity replace Google?
For research-style queries, many users find Perplexity more efficient than Google — it synthesizes results rather than returning a list of links. For quick lookups, local search, and shopping, Google still dominates. Perplexity and Google serve increasingly different search behaviors.
Can Perplexity write code?
Perplexity can write basic code and answer programming questions, but it's not optimized for coding tasks. For software development, debugging, and code generation, ChatGPT, Claude, or Claude Code are significantly better choices.
Is Perplexity Pro worth $20/month?
For heavy research users, yes. Perplexity Pro unlocks access to GPT-4 and Claude on top of Perplexity's retrieval, unlimited file uploads, and faster search. If you use Perplexity as your primary research tool and do more than 5-10 research sessions per day, Pro is worth it.
How does Perplexity make money if search is mostly free?
Perplexity monetizes through Perplexity Pro subscriptions ($20/month), enterprise API access, and an advertising product that is rolling out in 2026. The company has raised over $500M and is one of the fastest-growing AI products.
