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 [Profile (Markdown)](https://openaitools.app/tool/consensus.md) ## Lexal Lexal takes a deliberately lightweight approach to AI in the browser. Rather than opening a chat tab, it rides on the right-click context menu: select a sentence, choose a function, and Gemini responds in a small overlay. That keeps you in the flow of whatever you are reading instead of switching between windows. The extension bundles four related reading aids. Fact check tests a claim against the model's knowledge; Bias check examines how a piece of writing frames its subject; Summarise/TLDR compresses long content into a short overview; and the debate mode deliberately argues both for and against a proposition, which is useful for pressure-testing an argument before you repeat it. All of these return output in the browser's current language. Architecturally, Lexal is honest about what it is: a standalone wrapper around a large language model. It does not run its own inference or resell tokens — you paste in your own Google Gemini developer API key, and the extension simply calls that model under your own quota. The developer states that no user data is collected, sold or shared, which is a sensible posture for a tool that needs access to whatever text is on your screen. It is a small, focused utility rather than a full AI assistant, and it is best judged as such. **Pricing & Plans:** Free. Lexal is a standalone wrapper that runs on your own Google Gemini developer API key and does not charge for tokens; you only pay Google if you exhaust the free Gemini credit allowance. - **One-click fact checking:** Select any statement and get Gemini to verify whether a specific claim holds up, right inside the page you are reading. - **Bias detection:** Scan an article and have the model call out framing, slant and potential bias so you can read more critically. - **Summarise / TLDR:** Condense long articles, threads or documents into a short TLDR you can skim in seconds. - **Two-sided LLM debates:** Generate balanced, well-reasoned arguments for and against a topic to stress-test your own position. - **Browser-language output:** Outputs are returned in your browser's language, so the tool fits naturally into a multilingual browsing session. **Strengths:** Completely free, with no token markup or subscription; Runs on your own Gemini API key, so there is no third-party data middleman; Right-click workflow keeps you inside the page you're reading; Combines four distinct reading aids — fact check, bias check, summary and debate — in one small extension **Limitations:** Tiny user base and no reviews, so reliability feedback is limited; Requires you to obtain and manage your own Gemini API key; Last updated in July 2024, so it may not track the newest Gemini models; Right-click only workflow — no persistent sidebar or full-page interface [Profile (Markdown)](https://openaitools.app/tool/lexal.md) ## Frequently Asked Questions ### How do Consensus and Lexal compare in monthly traffic?
