Almost finished building an all-in-one AI studio for self-publishers. Here is my stack

Hey IH! 👋

For the past few months, I've been working nights to solve a problem I kept seeing: self-publishing is too fragmented and expensive. Authors have to buy separate tools for writing, AI editing, and formatting.

I'm putting the finishing touches on Pressdown.app. It’s a Markdown-based editor that includes an AI Ghostwriter (supports 35 languages) and instantly exports to professional PDF and EPUB formats.

The core engine is built (using NextJS, Docker, and PostgreSQL). I'm currently polishing the UI and fine-tuning the AI prompts to keep API costs down.

Would love some feedback on the UI from this community before I open the gates. What do you guys think?
