Glossary

Assistant The primary conversational AI interface in LexHub. The Assistant allows you to ask legal questions, analyse documents, and run workflows while grounding every response in the sources and documents you select.

Citations Inline references included in every AI-generated response that link back to the exact source passage the answer was drawn from. Citations allow you to verify AI output before relying on it professionally.

Credits The unit of AI usage in LexHub. Credits are consumed each time you interact with the Assistant, run a Workflow, or generate a Review cell. Your monthly credit allowance is determined by your plan.

Deep thinking mode An optional setting in the Assistant that prompts the AI to reason more thoroughly before responding. Useful for complex legal questions or multi-step analysis.

Dossier A curated collection of documents that forms the factual basis for legal work in LexHub. Selecting a Dossier limits the Assistant's context to only the documents inside it, ensuring AI output is grounded in matter-specific material.

History A chronological log of all past conversations with the Assistant. Chats in History can be searched, revisited, and continued at any time.

Legal sources The authoritative external sources the AI is permitted to draw from when answering legal questions. Available sources include EUR-Lex and Rechtspraak. Legal sources can be selected per query.

Playbook A structured set of contract review rules that encodes your firm's legal standards into explicit criteria, guidance, and evaluation thresholds. Playbooks are created in the web application and applied during contract review in the Word plugin.

Prompt A question or instruction entered into the Assistant to generate a response. Well-structured prompts produce more accurate and useful answers. See [Prompting and best practices] for guidance.

Prompt library A collection of saved prompts that can be reused, browsed, and shared with colleagues. The Prompt library helps teams apply consistent instructions when working with the Assistant.

Project A persistent workspace in LexHub that groups related chats, reviews, and documents around a specific matter, client, or transaction.

Reasoning A feature that shows the steps the AI used to arrive at a response. Reasoning helps you assess the reliability of an answer without requiring you to interpret raw model output.

Review A structured table for analysing multiple documents side-by-side against a consistent set of legal questions or criteria. Each row is a document, each column is a question, and each cell contains an AI-generated, source-backed assessment.

Source drawer A panel that opens within the Assistant or a Review to show the full list of sources used in a response, the original document or passage, and the highlighted text that supports the answer.

Template A Word document uploaded to LexHub that serves as the drafting standard for a specific document type. When used in the Word plugin, the AI adapts the content of the Template to fit the matter at hand while preserving its formatting, structure, and house style exactly.

Workflow A predefined, task-oriented AI action that guides users through a common legal task in a structured and repeatable way. Available workflows include Summarise document, Summarise redlines, Extract timeline, and Compare document versions.

Word plugin A Microsoft Word add-in that brings LexHub's AI capabilities directly into the drafting environment. The Word plugin supports Playbook-based contract review, the writing assistant, document summarisation, anonymisation, and translation.

Grounding The practice of limiting an AI's responses to specific, user-selected sources and documents rather than drawing from general knowledge. Grounding is central to how LexHub works — every response is anchored in the sources you choose.

Hallucination A term used when an AI generates information that is plausible-sounding but factually incorrect or unsupported by the source material. LexHub's citation system is designed to make hallucinations easier to detect by linking every claim to a verifiable source.

Large language model (LLM) The type of AI model that powers the LexHub Assistant. LLMs are trained on large volumes of text and can understand and generate human language across a wide range of tasks, including legal analysis, summarisation, and drafting.

Prompt engineering The practice of structuring and refining prompts to get better, more consistent results from an AI. See [Prompting and best practices] for LexHub-specific guidance.

Retrieval-augmented generation (RAG) A technique in which an AI retrieves relevant information from a defined set of documents or sources before generating a response. RAG is the foundation of LexHub's grounded, citation-backed answers.

Clause A distinct provision or section within a contract that addresses a specific right, obligation, or condition. Playbooks and Reviews in LexHub are typically organised around individual clauses.

Due diligence The process of systematically reviewing documents, contracts, and legal materials to assess risk before a transaction or decision. Reviews and Dossiers in LexHub are particularly suited to supporting due diligence workflows.

EUR-Lex The official online database of European Union law, including regulations, directives, and case law. EUR-Lex is available as a legal source in LexHub.

Governing law The jurisdiction whose laws apply to a contract or legal dispute. Specifying governing law in your prompts helps the Assistant produce more accurate and jurisdiction-specific responses.

NDA (Non-disclosure agreement) A contract that establishes confidentiality obligations between parties. NDAs are a common use case for Reviews and Playbooks in LexHub.

Precedent An existing document — typically a previously approved contract or template — used as the basis for drafting a new one. Templates in LexHub are typically built from precedents.

Rechtspraak The official database of Dutch court rulings and case law. Rechtspraak is available as a legal source in LexHub.

Redline A version of a document that shows changes made relative to a previous version, typically with additions underlined and deletions struck through. The Summarise redlines workflow in LexHub is designed to help users understand the legal impact of these changes.

SPA (Share purchase agreement) A contract governing the sale and purchase of shares in a company. SPAs are a common use case for Playbooks and Templates in LexHub.
