Compared a few options
Evaluated this against two competitors. Where it wins: works on output from popular LLMs and probability score with highlighted suspect passages. Where it lags: short inputs may yield unreliable verdicts. On balance the feature set — especially sentence-level highlighting of flagged content — justifies the 4 stars for our use case.
Use it every day
Honestly didn't expect to like it this much. Works on output from popular LLMs is exactly what I needed, and simple browser-based workflow. I do wish short inputs may yield unreliable verdicts, but I reach for it almost every day now and it just clicks.

Skeptical, then convinced
I went in skeptical — most tools in this space overpromise. It actually delivers on aI-generated text probability scoring, and fast analysis of pasted or uploaded text caught me off guard. still, I'd recommend giving it a real trial.
