Problems solved: chatGPT does a great job with editing a proposing useful edits to drafts of memos and legal documents. It acts as a quick "double check" on most of the work I do.
What could improve: Legal diagrams and spreadsheets. Connectivity with a major legal database like Westlaw or Lexis. Connectivity with major research sites like Bloomberg BNA or other legal or tax treatises.
