What ChatGPT does in legal practice

Core tasks in legal practice
Where ChatGPT excels
  • Versatile across a wide range of tasks
  • Strong at agentic coding and debugging
  • Multimodal: text, image and speech
  • Large ecosystem and integrations

ChatGPT has a well-documented GDPR profile and, with the right business settings, is usable in legal practice.

Confidentiality and GDPR

GDPR: Strong

Professional secrecy is mandatory. Only enter client data into a business/EU variant with a data processing agreement, where input is not used for training. Always keep a lawyer in the loop.

EU data residency available for Enterprise, Edu and the API. Business and API data are not used for training by default; consumer tiers (Free/Plus/Pro) are, unless you turn this off.

Rule of thumb Use the business variant with a data processing agreement, and keep a human in the loop for decisions that matter.
