Practical guides
Understand the task, not just the button.
Review an AI text cleanup before you paste it
Use staged changes, pinned phrases, code protection, and reference comparisons to review a cleaned draft instead of trusting a one-click result.
Turn a copied AI draft into a plain-text email
Keep the greeting, requests, names, and link destinations while removing chat-style presentation that does not belong in an email.
Clean an AI explanation without damaging its code
Understand protected code regions, indentation, fences, and why prose cleanup should be separate from code formatting.
