We applied to Y Combinator a few weeks ago and submitted a demo. We made significant progress since then and have a much better demo now. Is it possible to replace the demo? Is it advisable?

It’s fine to replace the demo, and definitely a good idea if your new demo is better. That said, don’t expect that anyone who has viewed the old demo will check out the new one. As a result the sooner you get the new demo in place the better.
