Market & competitive research
Perplexity
AdoptAn AI answer engine that researches the open web and returns cited, source-linked answers.
Verdict: Adopt — Worth paying for now — a clear win for most B2B SaaS PMs.
Enterprise search
Glean
WatchEnterprise search that answers questions across all of your company's connected apps.
Verdict: Watch — Genuinely useful, but situational — adopt it only if it fits your stack.
Which wins for PMs
Perplexity (Adopt) and Glean (Watch) both answer questions, but point in opposite directions. Perplexity researches the open web and returns cited answers you can put in front of leadership; Glean searches inside your own company's connected apps. A PM doing market and competitive work wants Perplexity; one hunting for the internal doc, ticket, or Slack thread that already answered the question wants Glean. They're complements more than rivals.
