## 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

## NNScholar

NNScholar organizes research as a project rather than a series of one-off chats. You start with a topic, DOI, PMID, arXiv ID, or a free-form research question, and the literature search turns that into a ranked set of sources that you can save into a persistent project library. From there the app becomes a reading environment: you can chat with individual PDFs, translate them, annotate them, and ask questions whose answers stay anchored to the specific paper in context.

The distinguishing piece is its evidence system. Instead of producing fluent paragraphs that may or may not be grounded, NNScholar maintains an evidence board that ties claims, sources, decisions, risks, and follow-up actions together, and lets you trace citations forward and backward from seed literature. Research agents and reusable 'academic skills' handle repeatable tasks such as data extraction, screening, synthesis, and verification, so the same workflow can be applied across a large batch of papers.

When the reading and evidence work is done, the same workspace carries you into writing: outlines, drafts, figures, and submission materials are assembled with nearby sources still visible. NNScholar also connects to academic infrastructure through MCP, including Zotero, OpenAlex, PubMed, arXiv, Crossref, and ClinicalTrials.gov, and supports multiple LLM backends as well as custom OpenAI- or Claude-compatible endpoints. Pricing runs on a single visible credits balance, with free starter credits and rolling monthly plans.

**Pricing & Plans:** Freemium with a single credits balance. New users get free credits, and there is a one-time intro month offer alongside rolling 40-day Lite, Pro, Plus, and Max plans that grant increasing credit allowances. Credits are consumed by AI screening, chat, PDF reading and translation, agents, and skills.

- **AI literature search:** Launch a literature review from a topic, DOI, PMID, arXiv ID, or research question, inspect titles and abstracts, and save the useful hits into a shared project library.
- **PDF reading and translation:** Chat with a PDF, translate it, annotate passages, and ask questions that stay scoped to the academic paper you are reading.
- **Evidence board and citation tracing:** Connect claims, sources, decisions, and open questions in one board, then follow references and related work forward and backward from your seed literature.
- **Research agents and academic skills:** Reusable agents and skills handle routine tasks such as screening, data extraction, synthesis, and source verification, which makes batch review work practical.
- **Broad model and tool connectivity:** Connect academic databases and reference tools through MCP, including Zotero, OpenAlex, PubMed, arXiv, and Crossref, and choose among multiple models or bring your own API key.

**Strengths:** Keeps sources, notes, and evidence in one persistent project instead of scattered chat threads; Evidence board and citation tracing make it easier to check whether a claim is actually supported; MCP integrations with Zotero, PubMed, arXiv, and similar tools fit real academic workflows; Flexible model choice, including bring-your-own API keys through OpenAI- or Claude-compatible endpoints

**Limitations:** Credit-based pricing means heavy agent use can be hard to predict up front; Desktop-app-first design is less convenient for purely browser-based workflows; Feature depth has a learning curve, so casual users may only touch a fraction of it
