What Can AI Take on for Lawyers and Legal Teams Today?

Anyone searching for AI is usually looking for an AI that can take on or accelerate concrete legal work. Modern Legal AI can review contracts, research legal information, edit documents, identify risks, and apply contract knowledge systematically.

The point is not that the AI replaces the lawyer. The point is which work it can take on reliably, and how much control stays with the legal team.

Which AI Is Suited to Legal Work?

An AI can produce a convincing legal text and still be unsuitable for professional legal teams. Because in a company it is not only about getting a legal answer. It is about deciding repeatedly by the same standards. That is why legal AI should meet five requirements.

Why Isn't ChatGPT Always Enough?

General generative AI can be highly capable at legal tasks too. It can summarise contracts, analyse clauses, formulate text, and answer legal questions.

For companies, however, an additional requirement arises: the AI must apply the company's standards consistently. This is exactly where a professional legal AI system differs from the purely prompt-based use of a general language model.

When you work with complex contracts, not simple NDAs, and use elaborate sets of rules for the review, for example with over 100 guidelines, then whether it's ChatGPT, Claude, or Copilot, none of them will do it precisely. The contracts and rulebooks are not fully captured and analysed, so you only get weak results you cannot rely on. Ask the same task with the same parameters multiple times, and you get different results each time. Legartis Legal Agent can fully analyse these data volumes and deliver precise results that stay consistent across repeated attempts.

The AI Quality Score is not one generic number. It shows quality at the level of each individual requirement in your playbook, based on ongoing feedback from your legal team. Every time you confirm or correct a result, that feedback recalibrates the score, so it reflects how reliably the AI meets your specific standards, not a general benchmark.

The AI takes on the operational analysis. It reviews contracts against your playbooks, flags risks and deviations, and prepares concrete change proposals. The legal team keeps legal judgment, negotiation strategy, complex risk assessments, final approvals, and accountability. The AI prepares the decision. The lawyer makes it.

Yes. Every result is broken down to the requirement level, so you can see exactly which playbook rule triggered which risk classification or change proposal, not just an overall verdict. Combined with the full audit trail, this makes every AI decision traceable and reviewable after the fact.

Every review, every correction and every decision is documented and traceable – for the team, for audits and for management.
