What you’ll be able to do

You can make long writing shorter and easier to read.

The problem

AI can make text longer by default unless you ask for compression.

What this skill does

Ask AI to reduce length while preserving key points.

When to use it

Best for: Emails, posts, reports, instructions

The move

The move: ask AI to cut length while keeping the key points.

Practice task

Try it now

Paste a long paragraph and ask for 30%, 50%, and one-sentence versions.

Self-check

  • The text is noticeably shorter than the original.
  • All names, numbers, deadlines, and action items survived the cut.
  • The tone still matches the original.

Common mistakes to avoid

  • Saying summarize this when you mean shorten it.
  • Giving no target length, so the AI barely trims.
  • Not checking whether a key detail was cut along the way.
