Perplexity

Web research with linked sources and follow-up questions.

Primary purpose

Perplexity helps investigate web questions with linked sources. Free Standard, paid Pro/Max and enterprise plans have different entitlements. Its developer API is a separate pay-as-you-go service; an app subscription should not be treated as API access. [P1, P2, P4]

Editorial strengths

Editorial assessment: linked sources can make it easier to revisit the basis of an answer.

Limitations

Citations do not guarantee correctness. API billing is separate.

Who it is for

Editorial fit: researchers, students and specialists who can independently check sources.
