Useful tools for generating marketing content? Hero Text, Ad Copy, etc?

I have been working on a low-code web app builder for the past couple years. Finally ready to publish my project and currently working on building the landing page (using my web app builder to build it 🤪).

I'm thinking about making a short, explainer video for all the features (developer centric, easy state management, components, lists, server side rendering, etc) but having really hard time coming up with short & precise tagline to describe my project.

Wondering if there are tools, perhaps AI based, that might help with generating such content?
