Why review your writing?
AI writing tools are common in essays, reports and everyday work. A careful review helps make sure the final text reflects what you actually mean.
Paste your draft, check sentence-level signals, and explore clearer wording before you submit, publish or share it.
No automated check is perfect. Use the tools to find passages worth revisiting, and keep your own judgment in the process.
Check and humanize.
One connected workflow.
A score is only a starting point. Review what was flagged, understand the feedback, and decide which passages need a new draft.
- Check essays, papers, articles and documents.
- Review individual sentences in context.
- Explore a more natural or academic tone.
- Compare the result with your original wording.
Everything your next draft needs.

What is an AI detector?
An AI detector analyzes writing patterns to estimate whether text resembles AI-generated or heavily assisted writing. It looks for signals such as predictable phrasing, repetitive structure and generic wording.
Use the result to find places worth reviewing in an essay, paper, report or document. It cannot establish who wrote a piece of text.
For essays, papers,
documents and more.
Bring the writing you are already working on. Leave with a clearer next step.
For academic writing
Review essays, research drafts, assignments and personal statements. Make your argument clearer while keeping your own thinking at the center.
For articles, blogs and client work
Revise articles, newsletters and freelance deliverables before sharing them. Choose the tone that fits your reader.
For professional documents
Make resumes, cover letters, reports and workplace messages sound clear, specific and personal.
For PDF, Word and TXT files
Paste text or upload supported documents in the writing tools. Review extracted text before running a check or rewrite.
For longer drafts
Use word counts and readability to plan revisions. Each tool shows its request limit; Pro unlocks full results within plan allowances.
AI Detector vs AI Humanizer
Two different jobs. One useful writing workflow.
| Your question | AI Detector | AI Humanizer |
|---|---|---|
| What does it do? | Estimates which passages read like AI-generated writing. | Rewrites text with more natural phrasing in your chosen tone. |
| When should I use it? | When you want to review writing signals before sharing a draft. | When a passage needs clearer wording, better flow or a different tone. |
A useful workflow: review the draft, inspect the feedback, then revise the passages that need it.
AI Detector vs Plagiarism Checker
AI-like writing and source overlap are different questions.
| Your question | AI Detector | Plagiarism Checker |
|---|---|---|
| What does it check? | Patterns that resemble AI-generated or heavily assisted writing. | Passages that match text in Wikipedia and research abstracts. |
| What can’t it prove? | Whether text was copied from an existing source. | Whether a human or an AI wrote the text. |
Original text can sound AI-like; copied text can sound human. Review both signals in context.
A signal. Not a final verdict.
No AI detector can guarantee who wrote a text. Results can vary with length, topic, language and editing history.
For academic or professional decisions, combine automated signals with human judgment, the original draft and clear review policies.
For the work that
makes you think.

Your questions, answered.
Can I use these tools for free?
Yes. You can try the tools without signing in. Humanizer and Paraphraser share 2 free trial runs with a 250-word result preview. Free AI detection includes 20 daily checks of the first 250 words. Word counting is free and runs on your device.
How does an AI detector work?
It examines patterns in text to estimate whether writing resembles AI-generated language. HumanizerKit shows sentence-level signals so you can inspect individual passages rather than relying only on an overall score.
Are AI detection results proof?
No. False positives and false negatives are possible. Topic, length, language and editing can affect a result. Use detection as a prompt for review, never as the sole basis for an academic or professional decision.
Will a rewrite keep my meaning?
The rewriting tools aim to preserve meaning and check important details such as numbers, links and citations. Always review the result yourself, especially factual statements and quotations.
Can I upload PDF, Word or TXT files?
Yes. The writing tools support .pdf, .docx and .txt uploads. Check the extracted text before submitting it. Scanned documents may not contain extractable text.
Do the tools work for essays and research papers?
Yes. Use them to review your own drafts, explore clearer wording and discover published sources. Follow your institution’s rules on AI assistance and verify every citation.
What changes when I sign in?
Your homepage becomes a workspace with recent work and a reference library. Pro features depend on your plan; your current allowances are shown in the workspace.
