http://recikeep.com
The site is centered around a bookmarklet with some extra server-side processing. You "recikeep" a recipe and the ingredients are all parsed out into Qty/Measure/Ingredient/Prep (as best as I can), and then you build menus from what you have kept. Since the ingredients are parsed out, I can generate a shopping list from your menu that's a combination of all of the ingredients across the recipes.
Any feedback would be greatly appreciated.
Thanks!
