## 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

## DeClassIFY

DeClassIFY installs as a browser extension and works on the PDFs you already download every day. Instead of opening each file to find out what it is, the extension reads the document and assigns it a category, turning a folder of mixed downloads into something you can triage at a glance. The pitch is simple: stop burning hours on files that were never useful to you.

The extension is intentionally narrow in scope. It does not try to be a full document manager, an editor or a cloud drive — it does one job, classification, and keeps the footprint small (under half a megabyte) so it stays out of the way of normal browsing. The listing states that the developer does not collect or sell user data.

Because it is distributed through the Chrome Web Store, installing and removing it takes a single click, and updates arrive automatically. It will suit researchers, students, analysts and office workers who collect large numbers of PDFs and need a fast first-pass filter.

**Pricing & Plans:** Free to install from the Chrome Web Store. The listing does not advertise a paid tier; any premium features, if they exist, are not described on the store page.

- **One-second PDF classification:** Reads a PDF and assigns it a document category immediately, so you can decide whether it deserves your attention.
- **Triage for mixed download folders:** Turns a pile of unsorted PDFs into labelled groups you can scan quickly instead of opening file by file.
- **Tiny footprint:** The extension is only a few hundred kilobytes, so it loads fast and does not slow browsing down.
- **Privacy-conscious design:** The developer declares that user data is not collected, sold or used for unrelated purposes.
- **One-click install and updates:** Installs straight from the Chrome Web Store and updates automatically, with no separate account required.

**Strengths:** Very fast classification that removes the manual step of opening every PDF; Small, unobtrusive extension that does not slow the browser down; Free to install and distributed through the official Chrome Web Store; Explicit statement that user data is not collected or sold

**Limitations:** Small user base at the time of writing, so community reviews are limited; Only classifies PDFs — it is not a reader, editor or file manager; No public pricing page describing premium tiers or higher limits
