Web filter for Chrome on Android

[AC Question]

I apologise in advance if this is a common question, but after scouring the web I have not found any good solution that offers web filtering for Chrome on Android. I would like to filter out certain categories of websites (for myself, not for another user; long story) without having to use a different browser, which seems to be the most common solution (along with blocking other browsers). I would also prefer not to root my device. Chrome has - incredibly - no settings for this, and extensions are not supported or even planned for Android. Is this just not possible?

Ps. I'm on an S7 with the latest Android, if that makes any difference.
