Should I open source it?

So I currently have 1 main startup (ai mvp generator) I am working on, but I plan to have one other side ai chat app.

So keep in mind that's 2, now I have another idea for basically AI generated blogs/articles for startups related to their niche.

But I don't have the energy or wish to make it a SaaS, I want it to be free, so should I just open source it as a mini personal project?

I have a good scrapping backend which I use in to get input & generate articles in it, so I think with few tweaks I can just make a free version for everyone?

It will be a good open source project for an 18 y/o right? Maybe for future portfolio?
