Is Blaze AI worth it for a small marketing team that already uses ChatGPT?

Our marketing team of three people already uses ChatGPT pretty heavily for drafting blog posts, social captions and email copy. It works well enough but we spend a lot of time re-prompting to get the tone right and the output still frequently sounds generic. A few people have mentioned Blaze AI as being better for maintaining a consistent brand voice and I am trying to figure out whether it is worth switching or paying for yet another tool on top of what we already use.

The thing that intrigues me most is the brand voice feature. We have a pretty distinct tone that took us a long time to develop and it is genuinely painful to try and describe it to an AI in a prompt every single time. If Blaze can learn and reliably apply our voice across different content types that would be a big deal for us.

What I want to know from people who have actually used it is how well the brand voice training actually works, how long it takes to get it to a point where the output sounds like us, and whether it maintains that voice consistently or whether it reverts to something generic after a few generations. Would also love to know how it compares to just building a very detailed custom instruction in ChatGPT.
