Transparency note: guide published by edit.legal, which appears in the list. Contract work is where AI delivers the most concrete return today, provided you pick the right tool for the right task: drafting from scratch, reviewing what the counterparty sends, or managing the signature cycle.

In brief

In 2026, AI contract drafting utilizes specialized tools such as edit.legal for Italian law (NDAs and leases) and contract review software like Luminance for M&A operations. Generalist models including ChatGPT, Claude, and Gemini generate preliminary drafts but lack verification of mandatory provisions, such as art. 79 of Law 392/1978. Legal validity necessitates professional oversight. The lifecycle concludes with qualified electronic signatures via providers like Aruba or Namirial to ensure full evidentiary value. AI accelerates drafting while professional responsibility for the text remains.

3.
Generalist models for non-binding drafts
ChatGPT, Claude and Gemini produce clause skeletons and preliminary term sheets in any language. The limit is structural: no verification of the provisions referenced, and clauses that may be void under Italian law (think commercial leases, where art. 79 of Law 392/1978 voids deviating terms).

4.
E-signature and lifecycle
A drafted contract must be signed and preserved: signature platforms (DocuSign, Yousign, and Italian qualified providers such as Aruba and Namirial) close the cycle. For full evidentiary value in the Italian context, prefer the qualified electronic signature.
5.
Method matters more than tooling
Whatever stack you choose: start from the contract's canonical structure, check mandatory provisions, use variable fields for party data and have a lawyer review every generated clause. edit.legal's free guides cover the most requested contracts, step by step.

Frequently asked questions

Can AI draft a valid contract on its own?

It can produce a complete text, but validity depends on mandatory provisions and consistency with the parties' intent: both require a lawyer's check. AI speeds up drafting; responsibility for the text remains professional.

What is the difference between AI drafting and AI contract review?

Drafting starts from scratch or a template and produces the contract; review analyses existing contracts to find clauses, risks and anomalies, typically at scale. They are different, often complementary, categories and tools.

Are the free templates I find online enough?

A generic template ignores the specifics of your case and often current mandatory provisions too. Better a template with verified legal basis and fields to fill in consciously, with a guide explaining each section.
