Young adult looking for roboinvest advice

I'll be the first to admit that I don't want to put too much effort into investment, and that I am extremely forgetful. Thinking of dumping my money into OCBC's roboinvest, so all the numbers sit in one central location for easy monitoring, and also that I don't forget that it exists.

I did some basic research and read that roboinvest has a high cost compared to other options? Is it still fine to do or would people here really recommend sucking it up and using a separate platform?

Edit: I'm worried that if I use a different platform/company it could go under, or that I'll forget it exists after a few years.
