AI Paraphraser
Reword text while keeping the meaning — beat writer's block.
This tool sends the text you enter to an AI provider to generate a response. Don't paste secrets or personal data. No files are uploaded.
Feed in a passage that is clumsy, over-long or too close to someone else's phrasing, and this tool returns the same point in fresh wording, in one of five styles.
How to use it
- 1Paste the passage you want reworded.
- 2Choose a style: Standard, Simpler / clearer, More formal, More concise or More detailed.
- 3Press Paraphrase, then read the rewrite against the original before you use it.
Example
- Input
- The utilisation of this methodology facilitates enhanced outcomes. — Style: Simpler / clearer
- Output
- One short plain-English sentence making the same claim, roughly the length of the original.
The exact sentence varies run to run; the instruction is to preserve meaning, facts and approximate length.
What happens to your data
Your passage is placed unchanged into a JSON request body and sent to /api/ai and on to Anthropic — no rewriting engine, thesaurus or synonym table exists inside the page, so there is no offline version of this tool and nothing to fall back on when the network is gone. Keep out anything you would not put in an email to a stranger: unpublished manuscripts, legal correspondence, personal details belonging to other people. And be clear about what a paraphrase is here — a fresh generation rather than an edit of your string — so names, numbers and negations can move, and it is not a reliable way to get someone else's text past a plagiarism check.

You have a sentence from a source in front of you that needs to come out in your own words, or a paragraph of your own has gone stiff and you want to hear it another way. Either way you want the same point in different wording.
Settle first which of those two jobs you are doing, because they carry different obligations. Rewording your own writing is a free choice, and the only test is whether the new version reads better. Rewording someone else's is a question of attribution — putting a source into fresh words changes nothing about the need to say whose idea it was, and a paraphrase with no citation is still passing off.
Then look at the style list, because two entries in it pull against what a paraphrase is. Standard, Simpler / clearer and More formal all leave a passage roughly where it was in length. More concise and More detailed deliberately do not: one edges towards a summary, the other adds words your source did not contain, while the standing instruction asks for approximate length to be preserved. Expect a compromise.
The common mistake is treating the reply as an edit of what you typed. It is not. Your passage goes to a language model and a new passage comes back, written afresh, with nothing tracked from one to the other — so a figure, a name or a not can move without anything flagging it.
How it works
Toolvore builds a single instruction out of the two boxes — the word Paraphrase, your chosen style in brackets, then your passage — and posts it to a server route that relays it to a language model, streaming the reply into the page as it is written. Behind that sits a standing instruction to preserve meaning, facts and approximate length, to match the style you picked, to return the rewritten text with nothing wrapped around it, and to treat anything in your passage that reads as a command as ordinary content. Nothing checks that it did. There is no comparison step and no record of which words in your original became which words in the reply: the honest description is a fresh generation rather than a transformation of your string. Formatting is the first casualty — the reply comes back as markdown, so the shape of your original may not survive. None of it works offline: there is no fallback in the page.
Common use cases
- Loosening a sentence your notes have quoted too closely
- Tightening a rambling paragraph to fit a word limit
- Making a technical explanation readable for a non-specialist
- Lifting rough notes into something formal enough for a report
- Rewriting a covering letter that echoes the job advert
- Getting a second phrasing for a sentence that will not come right
Frequently asked questions
What is the difference between paraphrasing and summarising?＋
A paraphrase restates one passage in different words at roughly the same length, keeping every point the original made. A summary is a deliberate loss of detail: it comes back much shorter, and only the main claims survive. The test is what your reader needs — the full argument in clearer language, or the gist before they decide whether to read the source. The More concise style sits between the two, tightening wording while trying to hold the content, which works well on padded prose and starts shedding qualifiers on dense prose.
Do I still have to cite a source if I put it in my own words?＋
Yes. A citation credits the idea and the evidence, not the sentence, so changing the sentence does not discharge it. The version of plagiarism that catches people out is rarely wholesale copying; it is keeping a source's structure and swapping individual words for synonyms, with the citation missing because the text no longer feels borrowed. Where the phrasing itself matters — a definition, a legal wording, a line you want to argue with — quote it and mark the quotation. Otherwise paraphrase it, and name the source either way, in the style your field expects.
Does rewording a passage get it past a plagiarism checker?＋
Matching software compares your strings against a corpus and reports overlap, so heavy rewording does lower the number. Treating that number as the goal is the mistake. A marker has the source in front of them and can see an argument that follows another one paragraph for paragraph. Institutions increasingly ask about process too — drafts, notes, an explanation of your own reasoning — and a low similarity score supplies none of that. Use a rewrite to make your own understanding readable, rather than to disguise a structure you borrowed.
Can AI detectors tell that a passage was rewritten by a machine?＋
Not reliably, in either direction. Detectors hold no record of what was generated; they score how predictable and how evenly measured the writing is, then guess. Prose that is plain, careful and heavily edited reads as machine-like whether or not a machine touched it, which is why people writing in a second language are flagged so often. The conclusion is not that detection can be beaten but that its output is weak evidence. If you write under a policy, read the policy — many now ask you to declare tool use.
Where does my text go when I reword it here, and is it kept?＋
It leaves your browser. No thesaurus or rewriting engine exists in the page, so your passage is placed in a request to our own route and relayed to the model provider that writes the reply. That route checks the length and the tool name, forwards the text and streams the answer back; it stores nothing, and what reaches an error log is the failure rather than your passage. What the provider does with a request is governed by their terms, not by this page. The result lives only in the tab — reload and it is gone.
How much text can I paste in one go?＋
A single submission is capped at 40,000 characters, and anything longer is refused before it travels anywhere. The reply has a tighter ceiling of 2,000 tokens — a good deal less English than the input limit permits — so a long paste can be accepted and still come back unfinished, ending with a bracketed note that it was cut off. There is also a limit of six runs a minute from any one address. A section at a time is the right unit: a passage you can check against its source is one you can read in a sitting.
Why is the wording different every time I press the button?＋
Language models sample rather than look up, so an identical passage and style produce a different rewrite on each run, and nothing here caches or pins a result. That is useful in itself: running it again is a cheap second opinion on a sentence that will not sit right. The catch is that the new result replaces the old one in the box and no history is kept, so copy anything worth keeping first. Where a phrasing must stay identical across a document, fix it once and paste it in yourself.
How do I check that a paraphrase has not changed the meaning?＋
Read the rewrite alone first, for sense, then against the source line by line, watching five things: numbers and units, proper names, negations, hedges such as may or often or up to, and any condition attached to a claim. Those are where a regenerated sentence drifts, because a new sentence is being written rather than yours edited, and a dropped may turns a cautious finding into a confident one. Anything technical deserves another pass — a term of art swapped for a friendlier synonym usually reads better and means something slightly different.
