Paraphrasing restates someone's idea in your own words and sentence structure while keeping roughly the same length and full meaning. Summarizing is shorter than the original and captures only the key points, dropping examples and detail. Quoting reproduces the exact wording inside quotation marks and credits the source verbatim. Use a quote when the precise phrasing matters, a summary when you only need the gist of a long passage, and a paraphrase when you want to weave an idea smoothly into your own voice. This tool handles the paraphrasing step: it swaps synonyms, adjusts phrasing, and restructures some sentences so the text says the same thing differently. Paste your passage above, pick a style, and rephrase it in seconds, then add quotation marks or trim it down yourself if you actually need a quote or summary.

Paraphrasing is not plagiarism by itself, but using someone's idea without crediting them is, even when every word is different. Restating a point in new wording does not make the underlying idea yours, so academic and professional writing still requires a citation whenever the thought came from another source. Plagiarism happens when you present that idea as your own, or when your rewrite stays so close to the original that it merely shuffles a few words. A genuine paraphrase changes both vocabulary and sentence structure while preserving the meaning, and it sits next to a proper reference. Use this tool to draft a fresh version of a passage quickly, then read it to confirm it truly reads as your own phrasing rather than a thin edit, and always keep the citation to the original author in place.

The change intensity slider, which runs from 10 to 100 percent, controls how many eligible words the tool replaces in a single pass. At a low setting it swaps only a handful of words for a light touch that stays very close to your original, which is useful when the draft is mostly fine and you just want to break out of one repetitive phrase. Raising it toward 100 percent makes the tool reach for synonyms far more aggressively, producing a heavier rephrase that drifts further from the source wording. Higher intensity does not always read better, since more substitutions can introduce awkward word choices, so it pays to compare settings. Edited words are highlighted against the original so you can see exactly what moved. Paste your text above, start around the middle, and slide up or down until the balance of change and readability looks right.

After each rewrite the tool reports a similarity score and a words-changed percentage for every variation. The similarity score is a word-overlap measure, a Jaccard-style ratio comparing the unique words shared between your original and the rewrite against the total unique words across both; a lower number means the two texts share fewer words and the paraphrase has drifted further from the source. Words changed simply shows the share of words that were replaced. Both are quick, honest signals of how far the output moved, but neither is a plagiarism detector: they only compare the rewrite to your own input, not against the web or any published database. Treat them as a guide to how heavy the rephrase is, not proof of originality. Run a variation above, glance at the scores to gauge the change, then read the result and edit for accuracy.
