How Shorten works
Step 01
Empty sentences go first
Sentences that repeat what the passage already says are cut without a rewrite.
Step 02
Each passage gets a target
Your length applies to every passage, so nothing is squeezed to make room for another.
Step 03
The rest is tightened
Repetition, padding and wordy phrasing go; sentences that share a subject merge.
Step 04
Facts are checked
If the target and the facts conflict, the facts win and the passage comes as close as they allow.
Options
- Target length
- Keep 20% to 90% of the original. Default 50%.
- Write in
- Keep the language, or translate while shortening.

- How short can it go?
- You set the target, from 20% to 90% of the original. The facts set the floor: if a shorter version would lose one, it stops at the shortest version that keeps them all.
- Does it shorten every sentence?
- No. Sentences that are already tight stay; only words that do no work are cut.
- Is it a summarizer?
- No. A summary chooses what to leave out. The sentence shortener keeps every specific and cuts only how it is said.
