Key features	Sentence-level highlighting rather than a single score Calibrated confidence scores Detects partially AI-written passages in mixed text 10,000 characters per scan with no account Browser extension and free API at 1,000 requests a day	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
Pros	Sentence-level output shows where a judgement came from Genuinely free with a generous API allowance and no account needed Specific privacy statement: not stored, not shared, not used for training	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
Cons	AI text detection is not reliable enough for consequential decisions 99.2% accuracy is not a figure any detector has demonstrated in the wild False positives fall hardest on non-native English writers	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
