captioning similar to Premiere Pro

I'm being asked to create captions both for animations/videos created in After Effects with little or no crossover with Premiere Pro or more elaborate captions than Premiere can handle on its own. I know some plug-ins exust but they're a very mixed bag with most really for Premiere Pro but with the ability to use MOGRTs created in AE. I'd love to simple be able to generate captions right in After Effects in a similar fashion as Premiere Pro so I can work with them directly in AE.
