Pricing and free plan

Pricing model: Freemium SaaS with free search access and paid Pro/Max/Enterprise-style plans; plan names and limits can change, so verify on Perplexity's help/pricing pages.

Free plan / trial assessment: Free usage exists, but advanced models, deeper searches, file handling, and high-volume use are limited.

Limitations

Answers still require source checking; not a substitute for expert review or primary-source reading.

ChatGPT / Claude comparison

Better than ChatGPT/Claude for this task — it is more specialized for live web research with source-first answers.
