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 [Profile (Markdown)](https://openaitools.app/tool/annotation-chrome-plugin.md) ## Leom Leom is a small, single-purpose Chrome extension built around one job: telling you whether you qualify. Instead of walking through a long eligibility questionnaire and waiting for someone to review it, you enter your details and Leom evaluates them automatically using what it calls the '3-1-0 rule' — 30 seconds to capture information, one minute to evaluate, zero human intervention. The extension sits in the Workflow & Planning category of the Chrome Web Store and is intentionally minimal, weighing only a few kilobytes. That keeps installation and updates fast and means there is no companion account or dashboard to manage. Adopted by a small but rated user base, it suits people who want a quick, repeatable eligibility answer rather than a full application portal. Because Leom is so focused, it works best as a first-pass filter: check eligibility in about a minute, then move on to the official process for whichever scheme, program or offer you are assessing. It is not a general-purpose AI assistant, and it does not store or publish your results. **Pricing & Plans:** Leom is listed as a free extension on the Chrome Web Store, and the developer discloses that no user data is collected or sold. The store listing notes that the extension may offer in-app purchases, so check the listing for the current details. - **Instant eligibility assessment:** A compact extension that evaluates eligibility from a short set of inputs instead of a long manual questionnaire. - **3-1-0 rule workflow:** The '3-1-0 rule' frames the whole flow: fast data capture, a roughly one-minute evaluation, and no manual review queue. - **Runs directly in Chrome:** Runs in the browser toolbar and installs from the Chrome Web Store in a few seconds. - **Automated, human-free evaluation:** Returns a direct assessment rather than a report you have to interpret, so the next step is obvious. **Strengths:** Answers eligibility questions in around a minute instead of a long form; Tiny download that installs and updates quickly; No account, dashboard or setup required; Developer states no personal data is collected or sold [Profile (Markdown)](https://openaitools.app/tool/leom.md) ## Frequently Asked Questions ### How do Annotation Chrome Plugin and Leom compare in monthly traffic?
