How the paraphrasing tool works
Three steps take a passage you are unhappy with and turn it into three alternatives you can compare side by side.
Paste your text
Drop in a single sentence or a full paragraph. The tool handles anything from a stiff line of dialogue to a whole descriptive scene without a word limit.
Choose a mode
Pick how you want it rewritten: fluent for flow, formal for register, creative for color, shorten to cut, or expand to add depth. Each mode changes the approach, not the meaning.
Compare three versions
You get three distinct rewrites in seconds. Read them against your original, copy the one that fits, or run another mode to see the passage from a different angle.
When authors reach for a rewrite
Paraphrasing is not about avoiding plagiarism here. It is about breaking out of a phrasing you cannot unstick on your own.
The sentence you have read too many times
You have edited one paragraph so often that every version sounds the same. Three fresh rewrites give your ear something new to react to so you can finally choose.
Matching the tone of a scene
A line lands too casual for a tense moment, or too stiff for a warm one. Switch between formal, fluent, and creative modes until the register matches the voice and perspective of the scene around it.
Trimming or padding to fit
A paragraph runs long for a pacing beat, or a description feels thin. Shorten and expand modes adjust the length while keeping the substance you wrote.
Frequently asked questions
No. Every mode is built to preserve the meaning, facts, names, and events of your passage. It changes the wording and sentence structure, not what the passage says. The one exception is that shorten trims detail and expand adds it, by design.
Standard keeps tone and length steady. Fluent smooths flow. Formal raises the register. Creative adds vivid language. Shorten tightens. Expand adds depth. Run the same passage through a couple of modes to see which direction suits it.
You can paste a single sentence or a long paragraph. The tool rewrites the whole thing you give it rather than truncating it, so you get a complete alternative, not a partial one.
The tool is tuned to produce natural, publishable prose rather than a mechanical thesaurus swap. That said, every rewrite is a starting point. Read it aloud, keep what fits your voice, and change anything that does not sound like you. If you want a second read, our AI content detector flags any lines that still read generic.
No. This tool works on one passage at a time, which is ideal for a stubborn sentence or paragraph. When you want to draft, restructure, or edit a full manuscript, that is what the AIWriteBook writing workspace is for. To catch outright grammar and spelling slips, reach for our grammar checker.
