Does anyone know of similar tool for Facebook?

Especially custom text comment replacement.

That's a great idea! I'm not on Facebook so this would be hard for me to develop, but I'd be open to turning this into a general tool that works with Facebook or other platforms.

It's a certainty that Facebook/Meta does not make it simple to programmatically modify and remove comments as eg Reddit. Not-surprisingly, no similar tool has been made yet - despite the dire need for one.

I wouldn't ask or expect that your tool be bogged down by the task, but surely it would make for a great separate project by any developer.
