## 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

## Review Express

Review Express is a Chrome extension built around one of the most repetitive tasks in research: getting through a long paper fast enough to decide whether it matters. Instead of a general-purpose summariser, it ships with pre-engineered prompts aimed specifically at scientific papers, and lets you choose a summary mode that matches why you are reading - a broad overview, the key findings, or something in between.

The published version works on highlighted text. You select a passage on a journal site or any web page, trigger the extension, and get a summary in your chosen mode. You can also ask direct questions about the selection, which is handy when you need to check whether a paper actually supports a specific claim before citing it. The developer notes that the extension consults the surrounding article text as well as your selection, so summaries are more contextual than the highlight alone would suggest.

Review Express is a small, early-stage project - the public version is 0.1.x and the developer describes more features as forthcoming. It is currently English-only in the interface, and it is an independent tool rather than something published by a journal, university, or AI vendor. For a research workflow where you read many abstracts and papers in a day, that narrow focus on scientific summarization is the main reason to try it.

**Pricing & Plans:** Freemium. The extension is free to add from the Chrome Web Store, and the developer also operates a web app at review-express-v1.vercel.app that offers a download and a sign-in, suggesting account-based paid or expanded usage. No specific plan prices or free-tier limits were published on the pages checked, so exact quotas should be confirmed in the app itself.

- **Prompts built for scientific papers:** A pre-engineered prompt library tuned for journal articles, so summaries focus on the parts researchers actually need rather than generic gist.
- **Multiple summary modes:** Pick from different summary modes depending on whether you want an overview, the key findings, or a specific angle on the passage.
- **Ask questions about the selected text:** Go beyond summarizing by asking targeted questions about the text you have selected, useful for checking whether a paper supports a claim.
- **Journal articles and general web pages:** Works on journal sites as well as ordinary web pages, so long reports, documentation, and news articles are fair game.
- **In-browser workflow:** Runs inside Chrome on the page you are already reading, with no separate app or dashboard to switch to.

**Strengths:** Prompts are purpose-built for scientific papers instead of generic summarization; Several summary modes let you match the output to your reading goal; Question answering on selected text helps verify claims before citing; Works on journal sites and ordinary web pages alike

**Limitations:** Currently only summarises text you highlight, not entire documents in one pass; English-only interface; Early-stage release with a small user base and further features still promised
