PerplexityAI tool

Perplexity provides AI-assisted search and research with plan-dependent access to models, files and content creation. Standard is free and supports basic searches with limited advanced searches and uploads. Pro expands research and model access, while Max raises usage allowances. Enterprise plans add team administration and controls for internal information. The API is a separate pay-as-you-go product; a web subscription does not automatically include API usage. Read linked sources as well as generated summaries when checking an answer.
