Free tool to write & auto-publish to Medium, Dev.to, Beehiiv, Hashnode - would you use it?

I’m working on a free, open-source app that helps you create and publish content everywhere without juggling 5 different tabs.

Here’s the idea:

✏️ Write your article or just the main idea

🤖 Rewrite or polish it using GPT (with your API key)

📅 Draft, schedule, or publish instantly

🌐 Auto-post to platforms like Medium, Dev.to, Beehiiv, and Hashnode via their APIs (you’ll provide your own keys)

My main goal is to make content creation & distribution fast and centralized. No subscriptions, no lock-in just your tools, your content, your reach.

I’ll be launching it soon on PH, but before that…

Would you use something like this?

What features would you want before it ships?
