I posted this in another comment but couldn't help but notice this discussion since it seemed relevant. I've been working on https://mealsyoulove.com, which is a meal planning app that also integrates with Kroger and Instacart for ordering groceries. Jow looks similar (not sure what their pricing model is?), but I'm leveraging AI to build highly tailored recipes and meal plans while allowing you to also import your own recipes to incorporate.
