Loaded it up without signing in and was surprised how snappy the PDF merge was, no watermark nonsense. The humanize tool did a decent job on a rough draft but it's not going to fool a strict detector every time.
@smet1525458 Thanks for taking the time to test both the PDF Merge and Humanizer! Glad you liked the no-signup experience and the watermark-free PDF tools. You're right that no humanizer can guarantee the same result across every AI detector, since different detectors use different models and update frequently. We're continuously improving the humanization quality based on real-world testing and feedback. Really appreciate your thoughtful review!
The humanizer actually made my draft sound less robotic without turning it into mush, and not needing to sign up just to try it was a nice touch.
@cileskara98785 Thank you! That's exactly what we were aiming for—making AI-assisted text sound more natural without over-rewriting it. We also wanted people to try the tool instantly without the usual sign-up barrier. Really appreciate you taking the time to test it and share your experience!
