I specifically needed content that would not trigger AI detectors for client work and Rankify delivers on that claim. Quality is high enough that our editors only spend about 15 minutes per article polishing.

Cecilia Hernandez

Content quality inconsistent

April 17, 2025

Some articles are genuinely impressive, others feel hollow and generic. The inconsistency is frustrating when you are publishing under a brand name and quality matters. I do not always have time to do a deep edit on everything.
