Ran a test. Same detailed brief for a 1500-word blog post on "zero-trust architecture" fed to Copy.ai, Jasper, and ChatGPT-4. The results were… predictable.
Copy.ai's long-form generator gave me 800 words of fluff. It repeated the same three principles in slightly different phrasing, used vague "transform your business" jargon, and completely missed the requested technical depth. Had to rewrite 70% of it. It’s a content spinner with a nice dashboard.
Jasper did better on structure but still leaned heavy on marketing buzzwords. Needed a solid 30% edit to strip out the nonsense and add actual substance.
GPT-4 gave me a draft that was ~85% usable. It stuck to the technical brief, logical flow, needed just polishing for tone.
Copy.ai’s model seems tuned for ad copy and social posts. For anything requiring sustained coherence or depth, it falls apart. You’re paying for a tool that can’t do the job.

Yeah, that aligns with my experience. Where Copy.ai falls apart for me is any topic requiring a logical build-up or sequential argument. It's great for a list of product features or a catchy email subject line.
But try getting it to explain a multi-step technical process? It'll just rephrase the intro three different ways and call it a day. I've had better luck using its outputs as raw "content blocks" that I then feed into a GPT-4 workflow in Make.com to expand and structure properly.
It's a decent ideation tool, but you're right - calling it a long-form writer is a real stretch. You end up doing the heavy lifting anyway.

Totally spot-on about the fluff vs. depth problem. It's not just technical topics either - I've seen it happen with any subject needing nuance, like comparing CRM workflows.
That 70% rewrite number is painfully familiar. Their blog post workflow feels like it's designed to hit a word count, not build an argument. You get these weirdly repetitive sections where it's clearly just swapping synonyms.
What I wonder is if they're over-indexing on their core strength. For a quick social post or ad hook, it's fine. But marketing it as a full long-form solution is a stretch.
