Undetectable AI
Place AI detection and text humanization on the same platform, with additional AI image, PDF and audio detection, Chrome extensions and APIs; the official claims support for more than 50 languages, tiered subscriptions based on word count, and compliance boundaries should be noted for rewriting functions.
Updated: 2026-10-26
What is Undetectable AI?
Undetectable AI integrates "detection" and "reverse rewriting" into a single platform: it uses an AI Detector to identify which sentences in a text would be flagged as machine-written, and an AI Humanizer to refine stiff text into natural language. The official homepage shows that its tool matrix also includes AI Image Detector, Fake PDF Detector, AI Audio Detector and AI Job Applier, and it offers Chrome extensions, APIs and Business Solutions. The official states that it supports more than 50 languages, with the highest accuracy for English. It should be made clear in advance that functions like the Humanizer will alter a text’s performance on detectors; if used to bypass AI usage rules of schools or platforms, there are clear academic integrity and compliance risks.
Who is it for?
- Writers and content operators who want to check their work first before deciding whether to rewrite it
- Editors and auditors who need to verify the authenticity of images, PDFs or audio recordings
- People who write in Google Docs or Gmail and want to minimize the number of tabs they switch between
- Teams that need to integrate detection or rewriting capabilities into their own systems (via API)
- Marketing and copywriting positions who only want to polish AI drafts without circumventing rules
Key features
6AI Detector
You can scan text by pasting or uploading it. The official website describes it as "looking at your text like a detector", pointing out exactly which sentences will be identified as AI-generated, making it easy to revise sentence by sentence.
AI Humanizer
The official states that by adjusting sentence structures, enriching vocabulary and tone, it makes rigid text read naturally and scores as human-written on mainstream detectors.
Multimodal Detection
In addition to text, the official website lists AI Image Detector (to judge whether images are AI-generated), Fake PDF Detector (to judge whether PDFs have been tampered with) and AI Voice Detector (to analyze whether recordings are AI-generated).
Chrome Extension
The official website states that the extension brings detection and rewriting to Google Docs, Gmail, and any web page, eliminating the need to switch tools away from your current page.
API and Business Solutions
The official states that it provides API integration and enterprise solutions, with the enterprise solutions including more stringent data retention controls.
Pricing and Refund Commitment
The official website's pricing page shows word count-based tiers: for annual payment, it's $5 for 10,000 words per month, $9.5 for 20,000 words, $15.75 for 35,000 words, and $21.25 for 50,000 words. The official states that if the generated content is judged to be non-human writing, the humanization fee can be refunded.
How to use Undetectable AI
- First, run it through the free Detector to see exactly which sentences are flagged, then revise them in a targeted manner.
- This approach is more effective at preserving your original expression than pasting the entire text into a Humanizer.
- After revision, be sure to read through the text yourself: these tools only handle sentence structure and word choice.
- you remain responsible for facts, data, and logic.
- The official website also reminds users that the output still requires manual review.
- Compliance is the most important point to note here—if your school, journal, or platform explicitly prohibits using AI rewriting to bypass detection, using it may constitute academic misconduct or a breach of contract, and the risks far outweigh the benefits.
- A more reasonable use case is to have AI assist in making drafted text sound natural, while clearly disclosing how AI was used.
- When dealing with corporate content, first confirm the data retention policy.
- for more stringent controls, refer to Business Solutions.
- Pricing, free quotas, and refund terms are subject to the official website's on-page instructions and may be adjusted at any time.
