Typing animation in 2.81 I have looked everywhere around the internet and for some reason for something as simple as this, I have not found a satisfactory answer. 

So my question is simple; how do I make text appear like someone is typing it? 

I tried transparency with color ramps but the keyframes don't appear on the timeline or dope sheet so I instantly gave up on that. 

There was a typewriter addon or something but it's outdated, and I'm using Blender 2.81, Eevee. 

The build modifier would work if it didn't start building at the end of the sentence. Made me consider looking for fonts that were reversed. 

Would help me greatly if anyone could give me a solution. Thanks. 

Update: Have tried answers below, the typewriter addon works perfectly but nothing appears in the render, and the animation nodes crash Blender mid-render. Nothing still works.
If anyone is still looking for a simple way to do this without going full animation nodes, I've updated the typewriter addon and fixed the invisible text when render bug. Currently tested and working on 2.83.
