How to Automate Contract Review with ChatGPT / GPT-4o (OpenAI)

Extract key terms, flag non-standard clauses, compare against standard templates, and summarise risk points.

The problem

Legal review of routine contracts takes 2-4 hours per document. Most of that time is reading for standard issues a checklist could catch.

The outcome

Contracts arrive for legal review pre-annotated. Lawyers spend time on edge cases, not routine reading.

The tool

  3. 3
