Legal Assistant is an AI tool for legal research and document review, built around an organisation’s own legal knowledge base. It can search precedents, practice guidance, regulatory frameworks, and research materials, and review contracts, court documents, regulatory filings, and correspondence to summarize key provisions, obligations, and issues. Other supported tasks include regulatory navigation, matter research, knowledge queries, precedent and template retrieval, and drafting based on the organisation’s materials and house style. Responses cite source documents, sections, or authorities for professional review. The service is delivered through KnowledgeFlow in a customer’s Azure or AWS cloud infrastructure. The maker says customer documents stay in the organisation’s cloud tenant and are not shared with public AI models or used to train external systems. KnowledgeFlow supports Microsoft Entra ID authentication, document-level access controls, and managed identity, and records an audit trail of questions, answers, and sources. Legal Assistant does not provide legal advice; qualified legal professionals remain responsible for advice. Pricing is not public; the maker invites prospective customers to book a demo.

Legal Assistant: the full review
Legal Assistant supports research and document review grounded in an organisation’s materials, with citations and an audit trail. It is not a substitute for legal advice, and the organisation must keep its knowledge base current.
Legal Assistant is a web-based tool for legal research and document review using an organisation’s own legal materials. It is best suited to law firms and legal departments that need cited, auditable support for recurring work. Its value rests on combining internal knowledge search with controlled cloud deployment; teams needing legal advice or a self-serve published price should look elsewhere.
Overview
Legal Assistant searches precedents, practice guidance, regulatory frameworks and research materials, and can help with matter research, knowledge queries and drafting. It also reviews contracts, court documents, filings and correspondence, summarising key provisions, obligations and issues. That breadth makes it useful where lawyers repeatedly need to find and apply an organisation’s own knowledge, rather than rely on a general-purpose legal assistant.
It runs through KnowledgeFlow in a customer’s Azure or AWS infrastructure. The maker says customer documents stay in the organisation’s cloud tenant, are not shared with public AI models and are not used to train external systems. KnowledgeFlow supports Microsoft Entra ID authentication, document-level access controls and managed identity. Its audit trail records questions, answers and cited sources, while citations point to source documents, sections or authorities for professional review.
The maker states ISO 27001 and ISO 42001 certifications and describes Cyber Essentials certification. Its Trust Centre describes encryption at rest and in transit, role-based access controls, Azure Firewall and Microsoft Defender for Cloud monitoring. These controls may suit teams handling sensitive legal materials, though the organisation still needs to maintain the knowledge base and check recent legal developments against primary sources.
Key features
- Legal knowledge search: Search internal precedents, guidance, regulatory materials and research. This is most useful when relevant answers are scattered across an organisation’s own sources.
- Document review: Summarise provisions, obligations and issues across contracts, court documents, filings and correspondence. It can help focus review, but does not replace a qualified professional’s assessment.
- Citations and audit trail: Answers link back to source material, and interactions are auditable. That gives legal professionals a route to verify outputs rather than treating them as unsupported conclusions.
- Content reuse and drafting: The tool supports precedent and template retrieval and drafting based on the organisation’s precedents and house style. Its usefulness depends on the quality and currency of the supplied knowledge base.
- Related assistants: Contract Assistant, Research Buddy and Knowledge Assistant can be deployed alongside it in the same secure environment.
Pricing
Legal Assistant has custom pricing; prospective customers are invited to book a demonstration and discuss the product with the maker. No public price or trial is stated. That route is a poor fit for buyers who need to compare costs or start with a self-serve plan before contacting a vendor.
The Legal Assistant plan includes a precedent library, legal knowledge search, content reuse workflows, citation linking and AI assistance.
Platforms
Legal Assistant is offered on the web through KnowledgeFlow, deployed in the customer’s Azure or AWS cloud infrastructure. The maker says documents remain in the customer’s cloud tenant. The maker offers product demonstrations and lists first-line support documentation for KnowledgeFlow.
Who it's for
The maker identifies law firms, in-house legal teams, public-sector legal services, and legal teams in housing and social-care organisations as intended users. It is a stronger fit for teams with a maintained body of internal legal knowledge and professionals able to check outputs. It is not a source of legal advice: qualified legal professionals remain responsible for advice.
Pros and cons
Pros
- Grounded in an organisation’s materials: Search and drafting can draw on internal precedents, guidance and research rather than only general legal content.
- Verifiable outputs: Source citations and an audit trail help professionals check what informed an answer.
- Customer-cloud deployment: The maker says documents stay in the organisation’s cloud tenant and are not used to train external systems.
- Multiple legal workflows: Research, document review, precedent retrieval and drafting are covered within one legal assistant.
Cons
- Knowledge upkeep is the customer’s responsibility: An outdated knowledge base can undermine relevance, and recent developments need checking against primary sources.
- Not legal advice: It supports professional work but leaves legal judgment and advice with qualified legal professionals.
- Custom pricing and demo-led purchase: Buyers cannot assess a public price or trial before contacting the maker.

Verdict
Choose Legal Assistant if your legal team needs research and document review grounded in its own precedents and guidance, with citations and an audit trail in a customer-cloud environment.
