Kiro does have autocomplete. It's just not advertised on the product page as a star feature.

In my experience using Kiro you are still going to be hands on with the code. Personally I choose to turn AI powered autocomplete off because when I do touch the code manually it's usually for the purposes of working on something tricky that AI would likely not get right in autocomplete either.

However, the Kiro autocomplete is average in capability in my experience, and you can absolutely use it to write code by hand as well.
