I showed the app to a CTO friend who's been guiding me a little in the process of learning to code. In my naive "glad to have finished" type frame of mind.
And he grilled me. For about 30 minutes, too.
"Who is it for, why would people use it?"
For context - while I've been using it as a learning capstone for myself, I still think it has a chance of commercial viability. If it scratches my own itch, there must be a good chance others like me would find it helpful? From my eyes, the value has been self-evident as it clearly automates an existing process.
Though he insisted folks might just create a custom GPT. Or use an existing app like Copy AI. Or that it doesn't actually save time.
Objectively, he's right in that at this stage it's impossible to say whether it's useful to anybody else.
But that conversation helpfully nudged me to clarify these specific points for the value proposition:
It's for media buyers specifically, not B2C or for those not already playing with AI to generate a lot of copy.
Growl saves time generating copy because it's easier to edit inputs and generate a new output, than edit the history of a Chat GPT conversation and start all over again. Example, your LLM is overstating one aspect of the product, you can simply edit the product info rather than re-prompt the LLM / restart the conversation.
Growl gives you more technical control over copy (length, copywriting framework, which part of the copy, etc) than other tools like Copy .AI.
[Working on this now] But Growl will let you switch between the best models like Claude and Chat GPT, maybe Grok for people who like to test how different models understand and execute the writing task, rather than requiring different subscriptions.
So at the risk of having an ugly baby and not knowing it, I shall press on for the time being to see how this received by the media buyer community. But at least I'll have a clearer value-prop.
