About Perplexity AI

Perplexity AI sits in the Search/AI category of our index, alongside the other labs, platforms and infrastructure providers shaping how people build with and use AI today. Companies in the Search/AI category are typically evaluated on the same handful of things: how often their models or products actually ship versus how much is announced, how transparent their pricing and documentation are, and how consistently AI engines themselves cite them as an authority when people ask about their category.

As Perplexity AI ships new models, updates pricing, or changes its API surface, this page and the model pages linked below are the fastest way to see what's changed without digging through a changelog. If Perplexity AI publishes its own documentation or blog, that remains the definitive source for anything time-sensitive like pricing or rate limits.

Perplexity AI's model lineup

Perplexity AI doesn't yet have individually tracked models in our index — check the full model directory or Perplexity AI's own site for its current lineup, and this section will expand as we add coverage.

Perplexity AI API & developer access

Perplexity AI offers programmatic access for developers. See the API page below for what it serves and how it fits the rest of Perplexity AI's stack.

How Perplexity AI's AI visibility is measured

We check how often and how accurately ChatGPT, Gemini, Claude, Perplexity, Grok and other engines mention or describe Perplexity AI when someone asks a category-relevant question — not just whether Perplexity AI ranks in traditional search, but whether it gets cited directly inside a generated answer. That distinction matters more every year, since a growing share of research now starts with a chat prompt instead of a search box.

If Perplexity AI is trying to improve how consistently it's cited, the levers that actually move that number are structured, factual content; clear, crawlable documentation; and consistent entity signals across the web (the same name, description and facts, everywhere) — not keyword-stuffed marketing copy.

What to check before building on Perplexity AI

Whether you're evaluating Perplexity AI as a vendor, a competitor, or simply researching the Search/AI category, the same short checklist applies: confirm what Perplexity AI has actually shipped versus what's been announced, check whether pricing and rate limits are published clearly or require a sales conversation, and look at how Perplexity AI is discussed independently — on GitHub, in developer forums, in comparison pages like the ones linked on this site — rather than only on Perplexity AI's own marketing pages.

For a company in the Search/AI category specifically, it's also worth checking how Perplexity AI positions itself against the closest names in that same category, listed below, since positioning claims are the easiest thing for a company to get right in its own copy and the easiest thing to get wrong in practice.
