Perplexity: research, plans and source verification
Perplexity combines search with AI answers. A citation starts the verification process; it does not automatically prove the claim.

Capabilities and use
Open cited primary sources and check date, context and the exact supporting passage. Separate generated text, inference and established fact. Coverage, model and mode affect results; a source link cannot prevent incorrect or incomplete answers.
Costs and access
Free, Pro, Max and Enterprise differ in model, research and file allowances. Comet Assistant access depends on the plan and is not exclusively Max in the comparison. API usage is billed separately. Check current account prices, billing period and limits before subscribing; do not assume unlimited research.
Rights and data
Data guidance allows Free, Pro and Max users to disable AI data retention to opt out of future training use. This does not remove previously used training data or stop processing needed to run the service. The provider excludes Enterprise data from training. Review contract, file retention and connectors separately.
