## Overview

Undetectable AI focuses on a single practical problem: content that sounds machine-made can be penalized, flagged or distrusted. The platform's detector highlights which sentences a scanner would most likely mark as AI-generated, showing percentages before the humanizer even runs. Once flagged, the humanizer rewrites those segments with varied sentence structure, richer vocabulary and adjusted tone, aiming to keep the original meaning intact while producing writing that reads naturally.

Beyond the core text tools, the product range has expanded into media forensics. There are detectors for AI-generated images, voice, video and deepfakes, plus specialty utilities such as a fake PDF detector, a receipt checker and other document-verification tools. A Chrome extension brings detection and rewriting into Gmail, Google Docs and any other page you are typing on, and an API is offered for teams that want the humanizer embedded in their own workflows.

The platform reports more than 24 million users and supports 50+ languages, though English yields the most accurate results. Business Solutions add stricter data-retention controls, white-labeling and non-expiring credit packs for higher-volume clients. A free tier is available with limited words, and the vendor advertises a money-back guarantee when humanized output is still flagged.

## Pricing & Plans

Freemium. A free trial covers a limited number of words (currently 250). Paid monthly plans start around $9.99 for 10K words and scale to roughly $42.50 for 50K words, while annual billing discounts those rates by about half (roughly $5.00-$21.25 per month). Custom business tiers add non-expiring credits, redistribution rights and priority support.

## Key Features & Capabilities

- **AI Detector:** Scans up to 5,000 words at a time and highlights the specific sentences most likely to be flagged as machine-written, so you can see your text the way a detector sees it.
- **AI Humanizer:** Rewrites AI-flagged passages with different sentence rhythms, vocabulary and tone, keeping your meaning while making the prose read like human writing.
- **Media authenticity checks:** Detectors for AI images, voice recordings, video and deepfakes, plus specialty document tools for checking whether a PDF or screenshot has been manipulated.
- **Chrome extension:** Detect and humanize directly inside Gmail, Google Docs or any web page without switching tabs.
- **API and business options:** An API lets teams plug humanizing into existing pipelines, while business plans offer white-labeling, higher volumes and non-expiring credits.

## Primary Use Cases

- **Check a draft before submitting (Student):** Run an essay or assignment through the detector to see which paragraphs might be questioned, then humanize them so the final draft reads in your own voice.
- **Scale publishing without losing tone (Content marketer):** Process AI-assisted blog drafts through the humanizer to smooth robotic phrasing and keep a consistent brand voice across a high-volume content calendar.
- **Keep pages readable and unique (SEO specialist):** Pair the humanizer with the paraphrasing and plagiarism tools to produce pages that read naturally and pass editorial review before publishing.
- **Verify submitted media (Editor or fact-checker):** Use the image, audio and fake-document detectors to confirm whether a submitted picture, voice clip or PDF was AI-generated or altered before it goes to print.

## Strengths

- Detector and humanizer live in one workflow, so you can flag and fix text without switching apps
- Wide language coverage (50+ languages) with strong English accuracy
- Extra media tools (image, audio, video, deepfake, fake PDF) beyond plain text
- Chrome extension makes it usable inside the tools people already write in
- Free trial and a published money-back guarantee reduce risk for first-time buyers

## Limitations

- Detector results are probabilistic and can disagree with other detectors or with human reviewers
- Free tier caps out at roughly 250 words, so any real workload needs a subscription
- Word limits still apply even on paid tiers, so heavy publishing volumes require enterprise pricing
- Humanized output sometimes needs a light manual edit to preserve nuance and technical accuracy
