When this makes sense
Document Summarisation automation with ChatGPT / GPT-4o (OpenAI) works best when your team handles this workflow multiple times per week, inputs are consistent enough for pattern matching, and human review of exceptions is part of the process. It is less effective when every instance requires unique judgment or when regulatory requirements mandate human sign-off on every step.
