Perplexity vs Consensus compares two tools that answer with citations but draw on different sources. Perplexity, for example, searches the whole web, from news to forums. Consensus, by contrast, answers only from peer-reviewed research papers.
Our reviews also score Perplexity 3.4 and Consensus 3.3. So the choice depends mostly on the kind of question you ask.
Perplexity vs Consensus: The Short Answer
Choose Perplexity, first, for news, products, how-to questions and anything recent. It cites every answer, shows no ads, and had the best record in the EBU and BBC news study.
Choose Consensus instead, however, for questions science can answer, such as whether a treatment works. It searches more than 200 million papers, shows how many studies agree, and its Pro plan costs $12 a month billed yearly.

| Criterion | Perplexity | Consensus |
|---|---|---|
| Sources | The whole web | Peer-reviewed papers only |
| Paid plan | Pro $20/mo or $200/yr | Pro $20/mo, or $12 yearly |
| Free plan | Everyday searches | Unlimited paper search; 3 Deep reviews |
| Special feature | Citations on every answer | Consensus Meter of agreement |
| Independent evidence | Best in EBU and BBC study | None found |
| Training by default | Yes on Free and Pro; opt-out | Unconfirmed outside Enterprise |
| Our score | 3.4 | 3.3 |
Sources and Answers
Perplexity searches the live web and links each claim to its source. As a result, it covers recent events, products and practical questions that papers do not address, as our Perplexity for research guide explains.
Consensus, on the other hand, draws only on academic papers, so blogs and marketing pages never shape its answers. For yes-or-no questions, moreover, its Consensus Meter shows how many studies point each way.
Prices
Perplexity Pro costs $20 a month or $200 a year, and its free plan covers everyday searches. Its top models, however, sit on Max at $200 a month.
Consensus Pro, by contrast, costs $20 monthly or $12 a month billed yearly, and Deep costs $45 billed yearly. Its free plan also includes unlimited paper search and three Deep reviews a month.

Accuracy and Evidence
Perplexity had the fewest significant issues of the four assistants in the EBU and BBC news study, at 30%. It also had the lowest error rate in the Tow Center’s tests of AI search.
Consensus took part in neither, and we found no independent test of its answers. Its narrower sources, however, remove low-quality web pages from the mix. Our guide to AI benchmarks explained explains what each test covers.
Data and Training
Perplexity trains on Free and Pro chats by default, and its opt-out covers only new data. Consensus, by contrast, offers institutional data guarantees only on Enterprise, a pricing tracker notes, and we found no stated rule for other plans.
For either one, therefore, keep unpublished or sensitive material out until you confirm the terms. Our guide to which AI tools train on your data compares both.
Who Runs Each
