Paraphrasing Tool

You paste a text on the left, choose a mode, and the rewritten version appears on the right as it is produced. The tool keeps the meaning, the facts, the figures, the names and the order of ideas, and changes everything else: the words, the sentence boundaries, the construction. The aim is a text that says the same thing without being the same text.

That last point is what separates a paraphraser from a thesaurus. Swapping three adjectives for synonyms leaves a text recognisable and, for a plagiarism checker or a reader who knows the original, identical in substance and shape. A real paraphrase rebuilds the sentences: it merges two short ones, splits a long one, turns a passive into an active, moves a clause, and only then picks different words.

The tool was built to measure that. On a benchmark of texts across the seven modes, the rewritten versions reuse on average 3% of the original's five-word sequences. The first version of the tool reused 33%, and the academic mode 75%; the prompt was rebuilt until the rewrite became a genuine one. A twenty-character minimum applies, and texts of up to twelve thousand characters are rewritten in one pass.

• paste a text, choose a mode, read the result as it streams
• meaning, facts, figures and names are preserved
• sentence structure and vocabulary are changed throughout
• twelve thousand characters per paraphrase, no sign-up

Standard keeps the register and the length and rewrites everything else. It is the mode for the common case: you have a paragraph that says what you mean and you need it said differently — to avoid repeating a source, to refresh a text you have reused, or to find a second way of putting something.

Humanize removes the mechanical evenness of a text: it varies sentence length, drops the predictable transitions ('moreover', 'furthermore', 'it is important to note'), breaks up symmetrical lists and lets in a direct turn of phrase. It is the mode for text that reads as generated, or simply as flat. Formal raises the register — precise vocabulary, worked syntax, no contractions — for a letter, an application or an official reply. Academic goes further: impersonal tone, explicit logical articulation, technical terms preserved exactly.

Simple rewrites for a reader of about fourteen: short sentences, one idea each, everyday words, technical terms explained. It keeps every piece of information — it changes the reading level, not the content. Shorten condenses to roughly half, keeping the central facts and dropping details, examples and repetition. Expand roughly triples the length by unfolding what the text implies: definitions, reasoning, nuances, consequences — without inventing a single fact.

• Standard: same register, same length, different sentences
• Humanize: uneven rhythm, natural voice, no stock transitions
• Formal and Academic: raised register, precise terms
• Simple: readable from middle school, nothing lost
• Shorten: about half the length, essentials kept
• Expand: about three times longer, nothing invented

The first version of this tool had the same weakness as most paraphrasers: it returned texts that were 80% the original. The cause was instructive. The instructions given to the model listed what must be preserved before what must change, and a model that is told 'preserve the meaning, the facts, the names, the structure' concludes that the safest answer is to change nothing.

The current version states the opposite. It forbids reusing any sequence of five consecutive words, requires a different number of sentences, and demands a different starting point for each sentence. It sets an explicit word-count range for every mode. And it says plainly that a text which is already well written must be rewritten all the same — 'there is nothing to change' is not an accepted answer.

The measured effect was a drop from 33% reuse of five-word sequences to 3%, with the meaning intact. You can check it yourself: paste a paragraph, run Standard, and read the two versions side by side. They should say the same thing and share almost no phrases.

The most common reason to paraphrase is academic: you have read a source, you want to use its idea, and you must not copy its words. A paraphrase is the accepted way to do that, with one condition that no tool can satisfy for you — the source must still be cited. Rewording a passage and presenting the idea as your own is plagiarism whatever the wording.

Used properly, the tool helps with the part that is genuinely hard: finding a formulation far enough from the original to be your own. Run the passage through Standard or Academic, then read the result against the source. Check that the meaning has not drifted, that no nuance was lost, and that the technical terms are the right ones. Then cite.

A plagiarism checker compares texts by their shared word sequences, which is precisely what the paraphraser eliminates. But 'undetectable' is not the goal; 'honestly rewritten and correctly attributed' is. The plagiarism checker on this site lets you verify the first part; only you can do the second.

Text produced by a generator has a recognisable evenness: sentences of similar length, paragraphs of similar shape, the same transitions at the same places, a register that never moves. Readers notice it even when they cannot name it. The Humanize mode targets exactly those traits.

It imposes concrete constraints rather than vague ones: at least one sentence under eight words and one over twenty-five; no paragraph opening with a logical connector; a list of stock phrases that must disappear entirely; enumerations dissolved into sentences of different shapes. A direct phrase or an aside is allowed where it sounds natural. The result reads as written rather than assembled.

This is not a trick to fool detectors — detectors look at the same markers, and a humanized text will indeed score lower, but the point is the reader. A text with rhythm and specifics is simply better to read. If your starting text needs more than rhythm — it needs facts, examples, a position — no rewrite will supply them; that is writing, not paraphrasing.

Shorten is the mode where the tool has to make choices, and the choices are worth knowing. It keeps the central facts, the figures, the dates and the proper nouns that carry the main information. It drops secondary details, incidental precisions, examples, explanatory asides, non-essential adjectives, and any idea already stated another way. It merges neighbouring sentences systematically.

The target is about 40 to 50% of the original length. That figure required some engineering: a model asked to 'make it about half as long' returns two-thirds, because its default instinct to preserve everything fights the instruction. The tool now gives an exact word range and an explicit permission to cut, and states that a version which still says everything, a little shorter, is a failure.

Because things are removed, read the shortened version with the original in mind. A nuance that mattered to you may be among what went. If you want a shorter text that loses nothing, the summarizer on this site is the better tool: it extracts rather than rewrites, and highlights in your text exactly which sentences it kept.

Expand is the mode people are most wary of, and rightly: a tool that makes a text longer can do it by padding or by inventing. This one is told to do neither. It unfolds what the text already contains — spells out an implicit point, walks through a reasoning that was only summarised, defines a term, states a condition or a limit, draws a consequence the text assumes, restates an idea from a second angle.

What it may not do is add a fact, a figure, a date, a name or an example from outside the text. That rule is absolute in the instructions, and the target length of roughly three times the original is achievable without breaking it on most texts, because most texts imply far more than they state.

Use Expand on notes, outlines and telegraphic drafts that you need to turn into prose. Do not use it to hit a word count on a finished piece: a reader can tell padding from development, and so can a teacher. Read the expanded version and cut what does not earn its place.

Formal raises the register for professional and official writing: a complaint, an application, a reply to an institution, a message to someone senior. It chooses precise words, builds controlled sentences, removes contractions and conversational turns, and keeps the result readable rather than pompous — the instruction explicitly warns against the precious.

Academic is for essays, papers and reports. It removes the first person singular, makes the logical articulation explicit ('this follows from', 'by contrast', 'the consequence is'), and — this is the crucial rule — preserves technical terminology exactly while changing everything around it. A tool that swapped 'mitochondrial membrane' for a synonym would be worse than useless.

Both modes were the hardest to make work, because a text that is already formal or academic invites the model to leave it alone. The measured reuse in Academic mode was 75% in the first version. The instructions now say in so many words that an already-academic text must be entirely rewritten, and that this is the mode where the temptation to copy is strongest.

Simple rewrites for a reader of about fourteen — the level at which most public information, instructions and general-audience writing should sit. No sentence over twenty words. One idea per sentence. Active voice. Everyday vocabulary. Every technical term replaced by a plain formulation or explained in a few words.

The rule that distinguishes this mode from Shorten is that nothing may disappear. A simplified text is often slightly longer than the original, because explaining a term takes more words than using it. That is expected: the mode changes the reading level, not the amount of information.

It is the right mode for turning a specialist text into something a client, a parent, a patient or a new colleague can follow; for rewriting instructions; and for checking your own understanding — if the tool cannot simplify a passage, the passage may not say anything definite.

The tool keeps the language of the text: a Spanish paragraph is paraphrased in Spanish, a German one in German, a French one in French. It does not translate, and it does not switch languages partway through. The seven modes work in every language, with the register conventions of that language — polite forms, formal address, academic phrasing — applied as native writers use them.

Quality is highest in the major European languages and English, where the underlying model has the most material to draw on. In languages with a smaller written corpus, the rewrite remains correct but can be a little more conservative. In every case, the safest use is on a text you can read well enough to judge the result.

If you need the text in another language rather than reworded in the same one, that is a translation, and the AI translator on this site is built for it, with the same attention to register.

A paraphrase is a rewrite, and a rewrite can shift a nuance. The tool preserves meaning, facts, figures and names, and the measured results are good, but no automatic rewrite is beyond checking. Read the result once with the original in mind, and look for four things in particular.

First, negations: 'not', 'no', 'never', 'without'. A dropped negation reverses a sentence, and it is the error automatic metrics catch least. Second, figures and dates: they should be identical. Third, hedges: 'may', 'in some cases', 'according to' — a rewrite can turn a cautious claim into a firm one. Fourth, technical terms: they should be the same terms, not near-synonyms.

A text you have read this way is safe to use. The word count under the result is there to help: it lets you see at a glance whether the mode did what it promises on length.

• check negations: a dropped 'not' reverses the meaning
• check figures and dates: they must be identical
• check hedges: a cautious claim should stay cautious
• check technical terms: same terms, not synonyms

Ten a day without an account, on texts of up to twelve thousand characters — about two thousand words — each. That is enough for a student working through an essay, a writer refreshing a set of pages, or an editor polishing a day's copy. No card, no email, no sign-up.

A free account multiplies both figures by four. The counter runs over a rolling twenty-four hours, so two days' allowance cannot be spent back to back, and limits are applied by account and by network. There is no paid tier for the paraphraser: the limits keep the service fast, they do not sell a bigger version.

The text is sent to the server, rewritten, and streamed back. It is not stored, not added to any dataset, and not used to train anything. The only record kept is a usage counter needed for the daily limits. The rewrite is produced by a language model hosted under a business agreement that excludes training on submitted data.

If you paste something confidential — a draft contract, an unpublished manuscript, a personal letter — this is the policy that applies, and it applies identically to the other tools on this site.

Three tools on this site change a text, and choosing the right one saves time. The paraphraser rewrites: same meaning, different words, optionally a different register or length. The summarizer extracts: it keeps the important sentences and drops the rest, and shows you which is which. The grammar checker corrects: it finds mistakes and leaves everything else exactly as it was.

So: a text that is right but must be said differently — paraphraser. A long text that must become short without losing what matters — summarizer. A text that says what you want but has mistakes in it — grammar checker. And a text you suspect was generated or copied — the AI detector and the plagiarism checker, which do not change anything and only report.

The tool rewrites prose. It handles lists and headings, but a table, a code block or a formula will be rewritten as if it were a sentence, which is rarely what you want; take those out before pasting. Quotations between quotation marks are preserved as they are, since a paraphrased quotation is no longer a quotation.

Very short inputs — a single sentence — leave the tool little room, and the result may be closer to the original than on a paragraph. Twenty characters is the technical minimum; a few sentences is the useful one. And the tool does not know your subject: if a term has a specific meaning in your field that differs from its everyday meaning, check that the rewrite respected it.

Finally, if a text is bad because it is empty — no facts, no examples, no position — no mode will fix that. A paraphraser changes how something is said. What is said is up to you.

Take a plain paragraph: 'The company launched its new product in March. Sales in the first quarter exceeded forecasts by 20 percent. The marketing team attributed the result to the pre-launch campaign, which had run for six weeks on social media. Management now plans to extend the campaign to two more markets.' Four sentences, four facts, two figures, one month.

Standard returns something like: 'March saw the company bring its new product to market, and first-quarter sales came in 20 percent above what had been forecast. According to the marketing team, a six-week social media campaign ahead of the launch explains the performance; management intends to roll that campaign out to two further markets.' Same facts, same figures, same March — different sentences, a different number of them, and almost no shared phrases.

Shorten returns: 'Launched in March, the product beat first-quarter sales forecasts by 20 percent, a result the marketing team credits to a six-week pre-launch social campaign that will now be extended to two more markets.' One sentence, everything essential, half the length. Expand returns three paragraphs that define what 'exceeded forecasts' implies, spell out why a pre-launch campaign would drive early sales, and draw out what extending it to two markets means — without adding a single fact the original did not contain. Run the paragraph yourself and compare.

Short professional texts are where a paraphraser earns its keep daily. An email you have written three times to three clients and that has gone stale: Standard gives it a fresh reading in seconds. A cover letter that sounds like every other cover letter — because it was built from the same phrases as every other cover letter: Humanize breaks the pattern, and Formal restores the register afterwards if it went too far. A message that came out sharper than you meant: Formal softens it without changing what you asked for.

For a cover letter in particular, run Humanize, then read the result and put back one specific thing about you that no tool could know — a project, a number, a reason you want this job. That single sentence does more for the letter than any rewrite. The paraphraser gets the prose out of the way so that sentence can be heard.

Check names, dates and figures after any rewrite of a message you are about to send. They are preserved by rule, and it takes ten seconds to confirm.

The words get used interchangeably, and they should not be. Editing improves a text while keeping it recognisably the same: it fixes mistakes, tightens phrases, removes repetition, and leaves most sentences as they were. The grammar checker on this site does the first part of that. Paraphrasing produces a different text with the same meaning: every sentence rebuilt, the same ideas in the same order. That is this tool. Rewriting produces a different text with a different purpose — a new angle, a new audience, new content — and that is writing, which no tool does for you.

Knowing which job you need saves a great deal of time. If your text is good and has mistakes, edit. If your text is good and must not be the same text, paraphrase. If your text is not good, rewrite — and use the paraphraser afterwards, on the new version, if you want a second way of putting it.

Teachers reasonably ask whether a paraphrasing tool is a cheating device. It can be used as one — a student who paraphrases a source and submits the result without a citation has plagiarised, with or without a tool. But it is also a genuinely useful instrument for teaching paraphrase, which is a skill most students find hard and few are taught explicitly.

One effective exercise: give students a source paragraph, have them paraphrase it by hand, then run the same paragraph through the tool and compare the two. The comparison shows what a real paraphrase does — restructures, not just reword — and it shows where the hand-written version stayed too close. Another: run a paragraph through Simple and have students explain what was lost or made explicit. The tool becomes a way to see the operation, not a way to avoid it.

For the question of whether a submitted text was paraphrased from a source, the plagiarism checker is the relevant tool, and the discussion with the student is the relevant method. A paraphraser cannot tell you that, and neither can a detector.

A product description used on three marketplaces, a company boilerplate pasted into twenty press releases, a help article that must exist on two sites: search engines treat identical text on several pages as duplicate content and rank all of them worse. A genuine paraphrase — not a synonym swap — gives each page a distinct text with the same information, which is exactly what the situation calls for.

Use Standard for a version at the same length, Shorten for a summary-length version for a listing or a card, Expand for a long-form version of a short brief. Then read each result for the four checks above: negations, figures, hedges, terms. Product specifications and prices in particular must come through unchanged, and they will, but the ten seconds it takes to confirm are well spent before a page goes live.

One caution. Paraphrasing someone else's page to put it on yours is not content reuse; it is plagiarism, and the plagiarism checker on this site would find it if the rewrite stayed close. The tool is for text you have the right to use.
