Solo founder, non-dev: Built micro-SaaS for paid media with $0 in tools. Feedback needed

The micro-SaaS: Tool for paid media professionals to plan campaigns, research keywords, create copies, static and video creatives and centralize reporting

The stack:

- Built with AI assistants (Google AI Atudio, Antigravity, Claude, ChatGPT)

- Firebase backend

- Vercel hosting

- $0 spent on dev tools (all free tiers)

The situation:

I'm a media buyer, not a developer. This started as a solution to my own workflow chaos and turned into a year-long obsession.

Now I'm staring at it thinking: is this actually useful to anyone else, or just me?

What I need:

- Honest take on the landing page

- If you do paid media, would this save you time?

- What's the first thing you'd improve?

- Is my pricing completely off? (haven't set it yet, that's another problem)

Happy to share the full journey of building this as a non-technical founder if anyone's interested. Right now I just need reality checks before I embarrass myself on Product Hunt.
