## 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

## Scribbr

Scribbr was built around a simple promise: help students submit work they feel confident about. The core of the service is human proofreading and editing, delivered by a hand-picked pool of academic editors who go through an in-house training programme before they are allowed to take orders. Documents are returned with tracked changes, in-text comments and a short personal letter explaining the reasoning behind the main edits.

Alongside the human service, Scribbr offers a growing library of AI writing tools. The Academic Check bundles together grammar and language review, citation checking, plagiarism scanning and AI-content detection into a single upload, which is convenient when you want one pass over an entire paper rather than juggling separate tools. Individual utilities such as the citation generator for APA, MLA, Chicago, AMA, IEEE and ACS, the paraphrasing tool and the text summarizer can be used on their own without paying for an edit.

The platform also maintains a large free knowledge base of academic writing guides that has become one of the more popular ways students discover the brand. Pricing depends heavily on document length, chosen turnaround time and add-on checks, so the practical way to get a number is to upload a file and select services in the order flow.

**Pricing & Plans:** Freemium model. Free tools include the citation generator, grammar checker and summarizer. Human proofreading and editing, the plagiarism checker, AI detector, AI proofreader and Academic Check are paid per document, with the final price depending on page count, delivery speed and any add-on checks such as structure or clarity review.

- **Human proofreading and editing:** A vetted academic editor reviews your paper within hours and returns tracked changes, comments and an explanation letter.
- **Plagiarism checker:** Scans your document against a large web and publication database to surface potentially unoriginal passages before submission.
- **AI detector and AI humanizer:** Flags text likely generated by large language models and offers a rewriting mode aimed at making AI-assisted drafts sound more natural.
- **Citation generator:** Creates and verifies references in APA, MLA, Chicago, AMA, IEEE and ACS styles from a URL, DOI or title search.
- **Academic Check bundle:** Runs grammar, citations, clarity, plagiarism and AI-detection checks in a single upload of the whole document.

**Strengths:** Combines human editors with AI tools rather than relying on one alone; Strong editorial vetting process and a large pool of academic specialists; Free citation generator and knowledge base are genuinely useful on their own; Transparent turnaround options starting from a few hours

**Limitations:** Paid services are priced per document, which adds up for long theses; AI detector verdicts can still be disputed by institutions; Some premium checks require you to buy them alongside an editing order
