Rewind looks cool - almost magical (I imagine part of the magic is due to the M1/M2 chips).

But I would be concerned overly relying on them. They've raised VC money, which means their future path is unclear. I don't know what direction their product will take if pushed by VC growth expectations. In particular, this is just a client-side only app with a pretty clear and finite feature set. But VC influence means there's a risk they will be shoehorning in features and online capabilities to promote growth.
