Skeptical, then convinced
I went in skeptical — most tools in this space overpromise. It actually delivers on no signup or login needed, and fast results for quick spot-checks caught me off guard. Limited advanced reporting or API features is why this isn't a perfect score, still, I'd recommend giving it a real trial.
Solid for our team
We rolled this out across the team last quarter and free to use with no account required. Suitable for quick content screening fits neatly into how we already work, and browser-based access removed a step we used to do by hand. No guarantee against false positives or negatives, which is the main caveat, but it has held up under daily use.
Use it every day
Honestly didn't expect to like it this much. Probability or confidence scoring is exactly what I needed, and simple, browser-based workflow. I do wish detection accuracy can vary by model and length, but I reach for it almost every day now and it just clicks.
