Undetectable AI bundles an AI text detector, an AI humanizer and an AI image detector into one account. The detector scans pasted or uploaded writing and shows which sentences flag as machine-generated. The humanizer rewrites stiff or robotic text so it reads naturally and scores as human on major detectors, with writing level matching. Further tools check whether a PDF is fake or edited and whether an audio recording is synthetic. Paid plans start at $9.99 per month for 10K words, with larger tiers at $19, $31 and $42.50 and discounts for annual billing.

Students and educators use it to review drafts before submission, while content writers and marketers check and adjust copy so it keeps a human voice. Professionals polishing client emails, reports and proposals are another group, as are business owners scaling content output without a bigger team. Agencies and publishers with heavy volume can ask for custom plans with non-expiring credits, white labeling and priority support, and developers can connect through API compatibility.

A typical workflow is pasting an essay or blog draft, running the detector, then humanizing the flagged passages and checking the result again. Journalists and moderators can run suspect pictures through the image detector before publishing, and recruiters or finance staff can verify a PDF. The Chrome extension adds the same tools inside Google Docs, Gmail and any webpage, so you can check or rewrite text without switching tabs. Subscribers also get an unlimited Human Auto Typer and unlimited AI detecting on every paid plan.

Frequently asked

6 questions
What does Undetectable AI actually do?
It detects AI-generated text, rewrites AI text so it reads as human, and checks images, PDFs and audio. The detector highlights the sentences that flag as AI so you know what to fix.
Who is Undetectable AI for?
Students, educators, content writers, professionals and business owners are the named groups. Businesses with high volume can arrange custom plans with bulk credits.
How could a writer use the humanizer?
Paste a draft that sounds robotic, run the humanizer, and re-check the output in the detector. The rewrite keeps the meaning while adjusting tone and reading level.
What does it cost?
Plans start at $9.99 per month for 10K words, then $19 for 20K, $31 for 35K and $42.50 for 50K words. Annual billing lowers these to $5, $9.50, $15.75 and $21.25 per month.
Is the free trial enough for real work?
The free trial is limited to 250 words, so it suits a quick test rather than full documents. Additional usage requires a paid plan.
Does it work outside the website?
A Chrome extension brings the detector, humanizer and paraphraser into Google Docs, Gmail and other pages. An API-compatible option is included with paid plans.
