Key features	Detects zero-width spaces and mixed-script lookalike characters Flags stylistic cues that read as machine-generated Reviewable evidence behind every flag Rewriting with a model you choose Free text inspection with no account	Rewrites AI-generated text using a non-AI algorithm targeting perplexity and burstiness Eight distinct rewrite modes for different tone and style outcomes Built-in AI detector that scores text for AI-pattern probability Plagiarism checker to confirm originality alongside humanization Browser-based editor with no software installation required
Pros	Hidden-character detection also works on documents you receive, not just your own Shows the evidence rather than returning a mystery score Explicitly disclaims being an authorship detector	Addresses detection and rewriting in one interface instead of two separate tools Multiple rewrite modes give users a fallback if one style does not pass detection Vendor states plan changes and cancellation take two clicks, with no lock-in
Cons	The rewriting capability overlaps with tools sold for evading AI detection Editing your own voice and disguising authorship are different acts using the same mechanism Stylistic cues are heuristics - human writing can trip them too	Independent tests have shown it failing to bypass detectors like GPTZero in some cases Can introduce awkward phrasing or grammatical errors when pushed to evade detection Raises academic-integrity concerns given its bypass-detection use case
