What this course is about

How to see quickly what changed between two versions of a contract, a policy or a spreadsheet: finding differences, picking out the changes that matter and writing a clear change summary for colleagues.

A supplier sends a “slightly revised” contract, HR sends a new version of a policy, finance sends an updated spreadsheet. Rereading everything line by line takes ages, and missing one changed number can be expensive. In this course {AI} becomes your careful assistant: it finds the differences, separates what matters from cosmetic edits and drafts a summary you can confidently send to your manager.
