Runs my AI-assisted drafts through multiple detection checks and humanises anything that flags. The output maintains the meaning and structure of the original while passing Originality.ai and GPTZero reliably. Does exactly what it promises.
Quick and effective. I use it as the final step before any AI-assisted content goes live. The multiple humanisation modes are useful for matching different content tones. Word count on the Basic plan is my only real limitation.
The processing speed combined with reliable detection bypass makes this a genuine timesaver. Works consistently well with output from ChatGPT, Claude and Jasper. Recommend testing on your own detector after to confirm results.
