Free Paraphrasing Tool — Academic, Formal or Concise

This paraphrasing tool takes one passage of English — up to 2,000 characters, roughly a long paragraph or two short ones — and returns a single rewritten version. Before you press Run, you choose one of three modes:

• Academic — suited to essays, theses and papers: precise verbs, hedged claims where the original hedges, no casual phrasing.
• Formal — for reports, cover letters and professional email: polite and complete, but without scholarly vocabulary.
• Concise — the same idea in fewer words, for word limits, abstracts and slides.

You get one result, not a list of synonyms to click through. The model is instructed to keep your meaning, your claims and your numbers as they are, and to change how the sentences are built rather than just swapping words.

Here is an illustrative example of the kind of change academic mode aims for. The input is a sentence a writer whose first language is Russian or Ukrainian might plausibly produce:

Input: «In this work there was made an analysis of the influence of social networks on the students, and it was found that they have big influence on their motivation.»

Example output: «This study analyzes how social media affects students and finds that it has a substantial effect on their motivation.»

Notice what changed and what did not. The finding is the same, and the output does not strengthen «big influence» into «proves» or «dramatically transforms». What changed is the skeleton: the impersonal «there was made an analysis» became a direct verb, «social networks» became the usual English term, and «big» became a register-appropriate adjective. Your output will differ run to run; always read it against your original.

Rewording someone else's idea does not make it yours. If the passage you paste summarizes a source, the paraphrase still needs the same citation — the tool changes wording, not authorship. It also does not check your text against any database, so it cannot tell you whether a passage is original or «plagiarism-free», and nobody honest can promise that from a rewrite alone.

The responsible way to use it is on your own sentences: a paragraph you drafted that says the right thing clumsily. If you are working from a source, read it, close it, write your own version from memory, and then use the tool to smooth your sentence. Our guide on how to paraphrase without plagiarizing walks through that process, and it explains why a rewrite that stays too close to the source's structure — patchwriting — is still a problem even with new words in it.

Most paraphrasing tools are tuned for native speakers who want variety. Non-native writers usually want something different: their idea is correct, but the sentence carries the grammar of their first language. Typical signs are articles missing or misplaced, word order copied from the original language, long noun chains («the analysis of the results of the research of the influence»), and false friends such as «actual» for «current».

A synonym-swapper leaves that skeleton untouched and changes the words you chose carefully, which can make the text worse — the pattern sometimes called tortured phrases. Rebuilding the sentence while holding the meaning still is the part that helps. The risk runs the other way too: a fluent rewrite can quietly change a claim. If your original said «may contribute to», check that the output did not turn it into «causes». You know what you meant; the model only knows what you wrote.

Each run accepts up to 2,000 characters. For a longer text, paraphrase section by section — it also makes checking each result easier. You get 10 free runs per day, with no account needed. Your text is sent to our AI provider to produce the rewrite and is not stored by us, not logged and not used for training.

If you want to keep working on the result — compare it with your draft, adjust a word, carry on writing — use Fix in the editor to open it in Diglot.

If only one sentence is bothering you and you want to compare several phrasings side by side, the sentence rewriter returns three options instead of one. If you are not sure what is wrong with a paragraph in the first place, run it through the sounds-translated checker first to see which patterns stand out, then paraphrase the sentences it points to.
