## 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

## HighlightGPT

HighlightGPT exists for the moment when a sentence on a webpage does not quite make sense and you do not want to break your reading flow to open a separate chat tab. You highlight the difficult passage and the extension sends it, together with a configurable amount of surrounding page text, to an OpenAI model that returns a plain-language explanation. Because the surrounding paragraph, heading and nearby argument are included, the answer tends to reflect what that sentence means in this specific article rather than a generic dictionary definition.

The extension exposes three levels of context so you can trade accuracy against cost: higher values pull in more of the page and give richer answers, lower values keep requests small and cheap. If a selection is too large for the model's request limit, HighlightGPT automatically reduces how much page content it ingests so the request still goes through. Double-click highlights are deliberately ignored, which prevents accidental triggers while you are simply selecting text to copy.

Setup is minimal but does require an OpenAI API key, and every explanation you generate is billed against that key. The project is a small, single-developer tool published under the name Sacrosaunt, and it upgraded its underlying model to GPT-4o in version 1.1.3. It is best understood as a focused reading aid rather than a full AI assistant suite.

**Pricing & Plans:** The extension itself is free to install, but it is not usable without your own OpenAI API key. You pay OpenAI directly for the tokens each explanation consumes, and larger context settings increase that cost. There is no separate subscription sold inside the extension.

- **In-place explanations:** Highlight a confusing sentence and receive a short explanation without leaving the page or opening another tab.
- **Three context levels:** Choose how much surrounding page text is sent along with your selection to balance answer quality against API cost.
- **Automatic request trimming:** When a selection plus page context exceeds the request size limit, the extension automatically lowers how much page content it ingests.
- **Double-click protection:** Accidental highlights created by double-clicking are ignored, so the tool only fires when you deliberately select text.
- **Bring-your-own-key design:** Runs against your personal OpenAI API key, keeping you in control of model choice, quota and spend.

**Strengths:** Explanations use surrounding page text, so answers match the article rather than a generic definition; No context switching — you stay on the page you are reading; Adjustable context depth lets you control how much you spend per explanation; Simple, single-purpose design with automatic handling of oversized requests

**Limitations:** Requires your own OpenAI API key, which adds setup friction for non-technical users; High context settings can consume your OpenAI quota quickly; Small user base and a narrow feature set — it explains text and little else
