Undetectable.ai
The largest vendor in the category, with a bundled detector check.
What it is
Undetectable.ai is the largest vendor in the humanizer category and bundles a multi-detector check so customers can see scores before and after. The business model is a monthly word quota. Its marketing has drawn the attention of detector vendors, which now train on its output; results against Turnitin and Pangram change with each model update on either side. The policy notes on the paraphrasers page apply.
