Drop in a draft from ChatGPT, Claude, Gemini, or any other AI writer. ZeroTell reworks the rhythm, phrasing, and flow so it reads like a person wrote it — without changing what you meant to say.
An AI humanizer takes text produced by tools like ChatGPT, Claude, or Gemini and rewrites it so it flows the way people actually write — varied sentence lengths, natural word choice, fewer stock phrases — while the ideas and facts stay exactly the same.
AI drafts in seconds — and detectors catch it just as fast. Run your draft through ZeroTell's AI Detector first, then humanize the flagged parts so the finished text sounds natural and genuinely yours.
Copy text from ChatGPT, Claude, Gemini, Copilot, or any other AI writer — or upload a PDF, Word or TXT file — and drop it into the ZeroTell editor.
Choose Academic, Formal, Neutral, or Conversational, set the rewrite strength, and let ZeroTell rework it without changing your point.
Read the new version, adjust anything you like, run it back through the detector, then paste it into your essay, post, or email.
Plenty of humanizers stop at trading words for synonyms, which leaves the robotic structure untouched. ZeroTell rebuilds sentences, varies their length and rhythm, and strips out stock AI phrasing — so the result doesn't just look different, it reads like a person wrote it.
Paste a draft and ZeroTell immediately points out the phrases and rhythms that read as machine-made — no account, no download. When you want the full rewrite, sign in and pick a plan; Basic handles up to 4,000 words per run and Advanced up to 6,000.
Pick the Academic tone for coursework and research. ZeroTell keeps a formal register, your argument structure, and your key terms, while varying sentence length the way real academic writers do. Facts stay put — nothing is added and nothing important is dropped — which makes it a natural fit for essays, reports, and literature reviews.
It doesn't matter where the draft came from — ChatGPT, Claude, Gemini, Copilot, or Llama. ZeroTell works on the text itself and turns it into natural, human-sounding writing that reads like your own. For a final pass on spelling and punctuation, run it through our Grammar Checker.
Remote work has fundamentally reshaped the modern workplace by offering employees unprecedented flexibility and autonomy. This transformation enables organizations to access a broader talent pool while significantly reducing operational costs.
Remote work has changed the way most of us do our jobs. These days, people get far more say over when and where they work, and companies can hire good people from almost anywhere — all while spending a lot less on office space.
Check your draft with the AI Detector and humanize the sections that read stiff or robotic before you submit — so the work you hand in sounds like you.
Turn AI-assisted first drafts into readable, publish-ready posts that keep your voice and read naturally to editors, platforms, and your audience.
Polish AI-assisted deliverables before they reach the client. More clients now scan the work they receive, so review and humanize it first.
Smooth AI-assisted abstracts, literature reviews, and proposals in the Academic tone while keeping your terminology and key points intact.
You can paste your text and get ZeroTell's quick analysis of AI-typical phrasing for free, with no sign-up. Getting the full humanized version requires an account and a plan. See the Pricing page for the current plans and prices for your country.
Basic is one rewrite pass and takes up to 4,000 words per run. Advanced is part of the Pro plans* and counts each word twice toward the fair use word allowance (*up to 60,000 words a day): it uses a larger model, then runs a second pass that rewrites only the sentences that still contain AI-typical phrases or flat rhythm, and finishes with a meaning check that compares facts, numbers and names with your original and shows you anything that may have changed. It takes up to 6,000 words per run. Credits aren't sold on their own, but credits already in your account (for example ones returned after a failed run, or left from a plan) can pay for Basic runs at 1 credit per 200 words. Neither mode can guarantee how another company's detector will score your text.
Yes. Upload or drag in a PDF, Word (.docx), TXT or Markdown file up to 10 MB and ZeroTell pulls out the text for you. Scanned PDFs that are only images can't be read — paste the text instead. Your file is only used to extract the text and is not stored.
Paste your draft, choose the Academic tone, and pick a rewrite strength — Balanced is a good default for coursework. ZeroTell keeps a formal register and your key points while varying sentence rhythm. Before you submit, read the result, fix anything that shifted, and run it through the AI Detector to see how it reads. Always follow your school's rules on AI assistance.
It depends on how you use it. Polishing a draft you wrote, or AI help your instructor allows, is ordinary editing. Using it to hand in AI-written work as your own, or to get around a no-AI rule, is cheating, and ZeroTell's terms don't allow it. Our Academic Integrity page explains what the tools are and aren't for.
All of them. ZeroTell works on the text itself, so drafts from ChatGPT, GPT-4o, Claude, Gemini, Llama, Copilot, Jasper, or any other AI writer are handled the same way — as is your own writing when it simply sounds too stiff.
That's the goal of every rewrite. ZeroTell changes wording, rhythm, and sentence structure while keeping your facts, arguments, and key points, without adding or removing information. Light strength makes the smallest changes and Strong restructures more freely. As with any AI tool, give the result a quick read before you use it.
Your text is processed only to produce your rewrite. Finished results are kept for up to 24 hours so you can unlock and copy them, then they expire. ZeroTell doesn't use your writing to train AI models, and the Privacy Policy has the full details.
Many humanizers just swap in synonyms and leave the robotic sentence patterns in place. ZeroTell rewrites at the sentence level — structure, rhythm, and word choice — and gives you four tones and three rewrite strengths to control the result. Every result is checked by the ZeroTell AI Detector, and it sits right next to the full detector, so you can check a draft before and after humanizing without switching tools.
Yes. It runs in any modern mobile browser — paste your text, humanize it, and copy the result straight from your phone. There's no app to download.
Paste a draft, pick a tone, and get writing that sounds like you — checked by the ZeroTell AI Detector.
