Consensus
Pros
- + Passed my known-literature recall test on three questions — the key studies I expected ranked in the top ten every time
- + Consensus Meter gives a genuinely fast read on well-studied questions, backed by papers you can open
- + MCP server and API made my generic assistant answer research questions with citations in minutes; 30 free calls a month is a real trial allowance
- + Free tier allows unlimited paper searches plus 3 Deep reviews and 10 Study Snapshots per month
- + Per-study AI one-liners matched the abstract in 7 of 10 spot checks I ran
Cons
- - The meter can show a strong lean resting on a dozen retrieved papers without foregrounding how thin the base is
- - Deep reviews inherit retrieval blind spots — on one fast-moving topic it leaned on older studies I knew had been superseded
- - Agentic features are metered tightly on the free tier (10 Pro messages, 3 Deep reviews per month)
- - Published-science only: grey literature, market reports and internal data are entirely out of scope
- - Very new papers can take time to surface in retrieval; one 2026 paper appeared only on an exact-phrase search
Perplexity AI
Pros
- + Inline citations held up in my spot-checks: most claims linked to retrievable sources that actually supported the sentence
- + Pro at $17/month billed annually (pricing page, at time of writing) covers serious daily research with model selection and Deep Research
- + Fast first tokens — under five seconds on typical factual queries in my testing
- + Free tier is genuinely usable for occasional questions, with citations included
- + Enterprise Pro at $40/seat/month buys SSO, admin console and org-wide knowledge search with a contractual training opt-out (Perplexity help center)
Cons
- - Thin-source answers slip through: one deprecated-SDK answer cited a forum thread that did not support the claim
- - Agentic Computer features run on credits (4,000 bonus on Pro) with no per-action meter I could find, so burn is hard to predict
- - Publisher blocks and crawl disputes leave gaps in the index on contested topics
- - Max at $167/month billed annually ($200 month-to-month per third-party capture) is steep for individuals
- - Enterprise plans exclude API access entirely — credits are a separate purchase (help center)
