Content strategist at TextPulse, here since the company started. Mark writes the product and technical coverage: how the humanizer works under the hood, what changes in each release, and what a specification actually means for your writing. His reviews of writing software come from using them on real documents rather than reading a feature list.
Undetectable AI is a general purpose humanizer sold as a monthly pool of words, from $9.99 for 10,000 words to $42.50 for 50,000. It produced the strongest Turnitin results of any humanizer we ran.
