Free AI content writers: worth your time or a race to mediocre?

Are free AI content writers actually useful, or do they push you toward a baseline that’s technically fine but creatively forgettable? I’ve been testing a few for client briefs and the output is rarely wrong but almost never interesting. Curious whether others are getting real value from free tiers or whether you hit the ceiling too fast for it to matter.

From a systems perspective the false positive rate is a deliberate parameter, not an accident. Financial institutions set the sensitivity threshold knowing it will block some legitimate transactions. Who bears the cost of those blocks is almost never surfaced publicly.
