The only service I've found like this.

lurid

I've searched far and wide for a service in which I can access all of my cloud drives at once. Everything else I've come across is either a scam, or too pricey. The fact that this service can be used online is also super convenient, as I have a Chromebook and can't install software (for the most part). Thank you so, so, so much for the time and work you put into Multcloud! It's truly amazing.
