## Consensus

Consensus works like a scholarly search engine supercharged by AI. Instead of returning a flat list of PDFs, you ask a natural-language research question and Consensus extracts claims from relevant papers, then shows you what the studies actually find. A Consensus Meter summarizes the weight of evidence for yes/no questions, so you can see at a glance whether scientists largely agree, disagree, or remain divided.

The platform indexes hundreds of millions of peer-reviewed papers spanning medicine, biology, psychology, economics and more. Answers link straight back to the source studies, and you can filter by study design, journal quality, sample size and publication year to separate stronger evidence from weaker signals. Features like Deep Search, Topic Synthesis and Skills let researchers build a working knowledge base over time rather than starting from scratch on every query.

Consensus is designed for researchers, clinicians, students and analysts who need trustworthy signals from the scientific record without drowning in irrelevant results. A free tier gives limited AI-powered searches each month, while paid plans unlock unlimited use, advanced filters and deeper synthesis.

**Pricing & Plans:** Freemium. A free tier offers a limited number of AI-powered searches per month; paid individual plans unlock unlimited searches and advanced research features, with discounted student pricing and team/enterprise options.

- **Evidence-grounded answers:** Ask a research question in plain language and get answers synthesized from peer-reviewed studies, with each claim linked to its source paper.
- **Consensus Meter:** A visual summary shows how the scientific literature leans on a yes/no question, indicating agreement, disagreement or mixed evidence.
- **Powerful filters:** Narrow results by study design, sample size, journal quality, publication year and more to prioritize high-quality evidence.
- **Topic synthesis and Deep Search:** Aggregate findings across many studies into structured summaries that map what is known and where the gaps are.
- **Research workspace:** Save papers, organize sources and build a persistent knowledge base for literature reviews and ongoing projects.

**Strengths:** Answers cite real peer-reviewed papers, so claims are verifiable; Consensus Meter makes it easy to gauge scientific agreement at a glance; Rich filters help separate high-quality evidence from weaker studies; Fast, clean interface designed around research workflows

**Limitations:** Free tier caps the number of AI-assisted searches per month; Coverage is strongest for STEM and health fields, lighter for some humanities topics; It guides you toward sources but is not a substitute for reading full papers

## PaperLens

PaperLens is designed for people who need trustworthy answers from academic literature rather than generic chatbot output. Its central claim is grounding: unlike a general-purpose assistant, every answer is tied to real papers, and the tool surfaces evidence strength, scientific consensus, key findings and stated limitations so you can judge how strong a claim really is. It searches across millions of peer-reviewed papers via sources including arXiv, Crossref and Semantic Scholar.

Beyond one-off questions, PaperLens acts as a research copilot. You can ask follow-up questions, drill into individual papers, and combine with real-time web search, aiming to replace the clutter of many open browser tabs with a single conversation. A library feature lets you save papers and generate structured wiki summaries covering findings, methods and limitations, and filters for date, quality and source help cut through irrelevant results.

Pricing is transparent and tiered, with a free entry point and monthly/yearly billing options. It is aimed at students, researchers and analysts who want faster literature review and defensible, citation-backed answers instead of unverifiable prose.

**Pricing & Plans:** PaperLens offers a free starting tier with no credit card required, plus paid plans billed monthly or yearly with discounts for annual billing. The Starter plan is around $8/month on yearly billing, and the Pro plan around $20/month, with unlimited searches and priority support on higher tiers.

- **Evidence-grounded answers:** Every response is tied to real peer-reviewed papers, with evidence strength, consensus, findings and limitations shown.
- **Research copilot chat:** Ask follow-up questions, dive deep into individual papers, and combine with live web search in one conversation.
- **Library and wiki summaries:** Save papers and generate structured summaries covering findings, methods and limitations.
- **Smart filtering:** Filter results by date, quality and source to surface the most relevant and credible research.
- **Multi-source search:** Queries academic literature across arXiv, Crossref and Semantic Scholar to broaden coverage.

**Strengths:** Answers are grounded in real peer-reviewed papers with visible evidence strength; Combines semantic search, chat, web search and library features in one tool; Transparent tiered pricing with a free plan and no credit card needed to start; Structured wiki summaries make paper review faster than reading everything in full

**Limitations:** Coverage and answer quality depend on the underlying academic sources; The most useful search and paper-chat capacity is behind paid tiers; It complements, rather than replaces, careful reading of the primary literature
