Reviewer scorecard
“Deep Research is legitimately impressive for technical evaluation — comparing libraries, auditing security postures, understanding architecture decisions. What used to take 2 hours of reading docs and Stack Overflow now takes 5 minutes and comes with citations I can verify.”
“Vendor lock-in concerns. Hard to migrate once you're committed.”
“Citations remain the core differentiator vs ChatGPT. Every claim is sourced and you can click through. Hallucination risk drops dramatically when the model knows it has to cite. Deep Research is good but sometimes slow — it works best when you have a few minutes, not seconds.”
“Perplexity Pages is the underrated bet — turning AI research into shareable documents is how knowledge workers will collaborate in the future. The roadmap (Deep Research, Pages, shopping, Pro with multiple models) is building the AI-native knowledge platform, not just a better search engine.”
“The API design is thoughtful. Integrates well with existing stacks.”
“Too expensive for what it offers. Plenty of open-source alternatives.”
