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	AI humanizer with light, medium and aggressive modes Bundled AI detector to verify the output Deep Scan sentence-by-sentence analysis Alternative rewrites per sentence V2 detection technology
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	Sentence-level control rather than one blanket rewrite Free tier before any of the paid plans Detector included, so results are checkable
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	Its purpose is defeating detection, and students are the first audience named Submitting rewritten work is academic misconduct at most institutions Detector evasion is an arms race; today's pass is tomorrow's fail
