When to use text diff with AI

Reviewing AI rewrites: ask Claude or ChatGPT to improve your writing, then diff the result to accept or reject specific changes.
Comparing prompt iterations: see how changing your prompt affects the output.
Checking AI edits on code: spot exactly which lines changed in a code review.
Contract / document review: paste original and AI-summarized versions to verify nothing was dropped.
