## Annotation Chrome Plugin

Annotation Chrome Plugin is a lightweight Chrome extension published by Lexis Nexis that supports document classification and categorisation work. Rather than replacing the host application, it layers on top of it: when a reviewer opens a document in Lexis360.fr or in one of the Sesame applications, the plugin adds controls for entering custom annotations by hand and for reviewing annotations suggested automatically.

The prediction side is powered by internal SIE web services. The plugin sends a request for the current document and receives annotations returned by a prediction AI component, which the reviewer can then validate. That human-in-the-loop step is the core idea of the product: the model proposes, the specialist confirms, and the validated label feeds back into the classification and categorisation pipeline.

The extension is small (around 340 KiB), ships in English and French, attracts a few hundred users and is still actively maintained, with version 4.0.4 published in September 2025. Because it is tied to internal Lexis Nexis web services and specific French-language products, it is best understood as an internal productivity tool for teams already working inside that ecosystem rather than an open standalone annotation platform.

**Pricing & Plans:** Free to install from the Chrome Web Store. It relies on internal Lexis Nexis web services, so practical use is limited to organisations and users with access to the associated Lexis360 / Sesame environments.

- **Custom annotation entry:** Add your own annotations to the document currently open in the browser, without leaving the host application.
- **Prediction-AI annotation retrieval:** Contacts internal SIE web services to fetch annotations produced by a prediction AI component for the document you are viewing.
- **Annotation validation:** Review and validate returned annotations so that human judgement is applied before labels are accepted.
- **Classification and categorisation support:** Designed specifically to help classify and categorise documents in editorial and legal content workflows.
- **Bilingual, lightweight build:** Ships in English and French at roughly 340 KiB, with no data sold to third parties.

**Strengths:** Adds annotation and validation directly inside the tools users already work in; Human-in-the-loop design keeps a specialist in control of the final label; Very small footprint and a narrow, clearly defined purpose; Still maintained by Lexis Nexis, with a recent release in September 2025

**Limitations:** Useful only if you have access to the internal Lexis Nexis / Sesame web services; Very limited public documentation and no self-serve onboarding; Tiny install base and a single public rating, so community support is minimal

## 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
