A deal team rarely has time to read everything in a data room. Language models can, which changes diligence from sampling to full coverage. The risk is a confident summary that misses or invents something. This post covers how to use AI for diligence with citations and checks that a deal team and its lawyers can rely on.

01

Extraction against a checklist

Diligence already runs on checklists: change-of-control clauses, exclusivity, termination rights, customer concentration, related-party transactions. Turn each item into a structured question and ask the model to answer it for every relevant document, with the exact passage. The output is a table the team can sort and challenge, not prose.

02

Citations, and why they matter

Models can return answers grounded in specific passages of supplied documents; Anthropic's citations feature, for example, returns the exact text each claim relies on [1]. In diligence this is the difference between a lead and a liability: a reviewer can open the clause in one click.

03

Coverage and long documents

Research on long contexts found models use information at the start and end of the input best and miss more in the middle [2]. For a 200-page agreement, process it section by section, record which sections were read for which question and report gaps explicitly.

04

Where people stay in charge

AI does not decide whether a clause is a deal issue. It makes sure the team sees every clause that might be. Keep the final red-flag report written and signed by the deal team and counsel, with AI findings as its appendix.

Industry reports such as Bain's annual private equity report track how firms are adopting these tools across the deal cycle [3].
