These are personally useful for me when I'm making blogs and doing journals.

I love to write professionally, so when I notice something doesn't look right...it doesn't make me feel very good- Let's say that-

Another suggestion is using Gboard for Android — it's amazing for text editing, and I use it all the time rather than my Samsung keyboard because I find it's not only better, but it's faster!

You also have the option to hold down on the Straight-quote and get a smart quote. Unfortunately, you can't make it an automatic option for Android as of yet, so these sites are VERY useful for a lot of people!
