SaaS to make localization easier for Laravel users

Hi Guys!

I would like to build my first product.

I'm a laravel expert and had run into the problem of localization (using different languages for the same site) in a few times.

The problem is that translations usually stored in files, which is hard to keep updated between multiple developers and the customers (whose actually translating the app).

My solution would be a SaaS software which stores all of your translations and make it syncable (with webhooks and commands) for every user.

I have seen a few solution for this but everyone wants to be general and able to integrate with 20-30+ framework which makes integration a little bit hard.

My solution would be able to integrate into already running laravel projects with only registering on the site and installing 1 composer page.

I'm also planning a chrome extension which allows "non-technical" users to edit translation files while looking at the exact same page which they want to translate.

Also on the SaaS's admin panel you can sing roles (developer, translator, customer etc) and languages for every user.

I have a few more advanced features in my head like:
-translation history management
-translation versioning
-automating translations with google translate
-able to entrust a professional to translate your site
-etc...

My questions are:
-What do you think about the product? Is it good enough? Would you use it?
-Is it marketable? I'm planning a subscription based pricing, what pricing model do you think would fit for this product?
-In your opinion which are the key features?

Any other comment and ideas are really appreciated!
