## Overview

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.

## Key Features & Capabilities

- **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.

## Primary Use Cases

- **Label documents consistently (Document reviewer / annotator):** Add standard annotations to each document as it is opened, keeping categorisation uniform across a review team.
- **Validate AI predictions (Content classification specialist):** Check the annotations returned by the prediction service and correct or confirm them before they are used downstream.
- **Work inside the existing workflow (Lexis360 / Sesame power user):** Annotate and validate directly in the browser without switching to an external labelling platform.

## 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
