How we compare
We compare each tool on the things that matter most to Perplexity users: whether it has a usable free plan, how clearly it shows sources, whether it searches the live web, its research and browsing features, what it does best, and what it costs. We use each provider’s own pricing pages and help docs, plus published independent studies, and we date every check.
We don’t publish our own star ratings or invented benchmark scores. AI tools change monthly, so treat any comparison as a snapshot and try the free plans yourself with your own questions. Our accuracy guide includes a simple self-test kit.
