Photosynthesis plays a crucial role in sustaining most life on Earth going. It is important to note that plants store only 1 to 2 percent of the sunlight they absorb. Furthermore, this remarkable process releases the oxygen we breathe.

How it works

  1. 1

    Paste, upload or dictate

    Paste text, upload a .txt or .pdf file, or use voice input. Pick an output language if you want the result in a different one.

  2. 2

    Press Humanize

    There is nothing to configure. The humanizer rewrites the draft, then checks the result against your original and shows you the score.

  3. 3

    Review it sentence by sentence

    Click any sentence to see two or three alternatives, and accept or reject each change. The meaning check flags anything that drifted, so you know where to look.

It tells you what changed

Every rewrite is checked against your draft. Instead of trusting it blindly, you see the parts that moved and fix them one sentence at a time.

Similarity score

A score for how close the rewrite stays to the meaning of your draft, shown after every humanize run.

Changed facts

Sales rose 1.5% (Lee, 2019) → Sales rose 15%

If a number, name, quote, citation, link or claim comes back different, it is flagged on the sentence where it happened. Here the figure changed and the citation went missing.

Sentence editor

Click a flagged sentence for two or three alternatives, or reject the change and keep your original. Select a passage to rewrite only that part.

Changes view

See every edit against your draft in one place, undo what you do not want, and copy the result with its formatting into Docs or Word.

What the humanizer does

  • Rewrites the patterns, not just the words

    AI text tends to repeat the same sentence shape, open with stock transitions and hedge everything. The humanizer varies rhythm and replaces filler with plain statements, so it reads like someone thought about it.

  • Sentence-level editor

    Every sentence in the result is clickable. You get two or three alternatives for it, and you can accept or reject each change. Select a passage to rewrite only that part.

  • Meaning check

    After each rewrite you see a similarity score against your draft and a flag on any number, name, quote, citation, link or claim that changed, so nothing slips through unnoticed.

  • Copy keeps the formatting

    Paste the result into Google Docs or Word and the formatting comes with it. The Changes view shows every edit, and undo takes back the ones you do not want.

  • 41 output languages

    Write in one language and get the result in another, or let Auto Detect keep the language you wrote in.

  • Upload a file or dictate

    Drop in a .txt or .pdf instead of copying text out of it, or speak your draft with voice input. Copy the result with one click or save it as a .txt file.

Why RealWrite

We would rather tell you what the tool won’t do than oversell it.

What it does

  • Varies sentence length and rhythm
  • Swaps stock phrases for plain ones
  • Checks the meaning after every rewrite
  • Flags every changed number, name, quote, citation, link or claim
  • Lets you accept or reject each change

What it won’t do

  • Promise that any detector will score the text as human
  • Add facts or sources that were not in your draft
  • Ask you to set tone, strength or other options first
  • Replace your judgment: read the result before you use it

Who it’s for

  • Students

    You used a chatbot to get past a blank page and now the draft sounds like everyone else’s. Rewrite it so it sounds like you, and use the meaning check to confirm every citation and figure came through. Check your course’s rules on AI use first.

  • Marketers and bloggers

    Product pages, newsletters and posts that sound like a person at your company wrote them. If a brand or product name gets reworded, the meaning check flags it.

  • Non-native writers

    Draft in the language you think in, get a natural version back, and compare it sentence by sentence so you learn what changed.

  • Busy professionals

    Turn a generated email or report into something that sounds like you on a normal day: shorter sentences, fewer “I hope this finds you well” openers.

Questions about the AI Humanizer

Yes, up to 300 words a day on a free account. Paid plans raise the limit: Essential 30,000 words/mo, Pro 100,000 words/mo and Business Unlimited words/mo.

We can’t promise that, and nobody can honestly promise it. Detectors change often and disagree with each other. The humanizer removes the patterns detectors look for, like uniform sentence length and stock transitions, and you can check the result with the RealWrite AI Detector before you use it.

It shouldn’t, and the meaning check is there to catch it if it does. You get a similarity score and a flag on any number, name or claim that changed, so you can reject those edits.

The meaning check flags it on the sentence where it happened. Reject that edit to restore your original wording, or pick one of the alternatives instead.

Yes. Select a sentence or a passage in the editor and rewrite only that. The rest of the text stays as it is.

A paraphraser swaps words for synonyms. The humanizer works on what makes text read as machine-written: rhythm, transitions, hedging and repetition. It also checks the meaning against your draft and shows you every change before you keep it.
