Plaid does support personal use (including personal use access for Chase). I'd actually be interested in seeing where you saw that it doesn't support Chase for personal access so I can make sure our messaging is clear and consistent on that front!

It's true that the current onboarding flow is not designed for personal use cases; we're currently in the middle of revamping it to make it less onerous for non-business users. In the meantime, I recommend you just fill out the questionnaire as well as you can. We know that some of the questions don't really make sense in a personal use context -- just try to answer them to the best of your ability and you should be fine.
