Not all AI text generators are created equal.
If you've used ChatGPT, Jasper, or Copy.ai, you know the output varies wildly depending on your prompts, context, and use case. So, which generator is best for marketing?
We ran a head-to-head test across 5 popular platforms using the same marketing brief. Here’s what we learned.
Prompt: “Write a 200-word blog intro for a SaaS company helping eCommerce brands reduce cart abandonment.”
We tested:
ChatGPT (free + GPT-4 Pro)
Jasper
Copy.ai
Writesonic
Catalyst Hub AI Assistant
| Tool | Strength | Weakness | Score (1–10) |
|---|---|---|---|
| ChatGPT | Strong logic | Lacked voice | 7 |
| Jasper | Concise, CTA-driven | Needs training | 7.5 |
| Copy.ai | Quick ideation | Fluff-heavy | 6 |
| Writesonic | Good tone | Weak structure | 6.5 |
| Catalyst Hub | On-brand, funnel-aligned | Doesn't learn about you | 9.5 |
✅ Catalyst Hub scored highest for marketers looking to drive conversion, not just generate words. It understands funnel stage, campaign objective, and audience tone.
Built specifically for growth marketers
Able to link content ideas to strategy
Good at prioritizing outcomes, not just content
The only major downside is that it doesn't learn about your business, so every time you start a new session, you have to explain who you are. To make this easy, we added a "prompt generator," which gives you a copy-and-paste crash course so ChatGPT knows all about your business in a matter of seconds.
If you want something that learns about YOU, we can help with that too. Starting with the foundation of our Catalyst GPT, we build you a bot that incorporates your business into the foundational documentation.
