What is an AI legal assistant?
An AI legal assistant is software that supports a specific legal task, such as answering a policy question, summarising a document, or checking a clause against a playbook, using natural language processing and machine learning. It is part of the broader legal AI category, but scoped to assist rather than act autonomously.
What tasks can an AI legal assistant handle?
Common uses include:
Answering business users' questions about policy or process without escalating to legal
Summarising contracts, matters, or long documents into key points
Checking a draft against a clause library or precedent set
Extracting obligations, deadlines, and key dates from a document
Guiding a user through a self-serve template, such as an NDA request
How is an AI legal assistant different from an AI lawyer?
An AI legal assistant is generally scoped to a task or a user interaction. An AI lawyer is positioned more broadly, as a digital counterpart handling a wider slice of legal work. In many platforms the underlying technology overlaps significantly, and the distinction is more about how the tool is framed and deployed than a hard technical line.
Can business teams use an AI legal assistant without legal's help?
Yes, and this is one of the main reasons organisations adopt one. A well-designed AI legal assistant lets a marketing manager generate a compliant NDA, or a sales team check a standard clause, without opening a request with legal at all. This is the mechanism behind self-service contract creation, covered in more detail in how AI is transforming contract management today.
What should you look for in an AI legal assistant?
The key differentiator is whether the assistant is connected to your organisation's own policies and delegation of authority rules, or only general legal knowledge. An assistant with no visibility into your delegation of authority structure cannot reliably tell a business user what they are and are not allowed to sign off on.
How does Plexus AI work as a legal assistant?
Plexus Counsel acts as a real-time assistant embedded directly in contract, matter, and compliance workflows, answering policy questions and guiding self-service requests using your organisation's own knowledge layer rather than generic legal data. See AI document automation for how this extends into generating documents directly.
