How it works:
Take a photo of your handwritten grocery list (even if your handwriting looks like a medical prescription)
Our AI recognizes the items and organizes them by store section (produce, dairy, etc.)
Shop with your newly organized, aisle-by-aisle digital checklist
No more backtracking to aisle 1 after you’re already at aisle 12. Your grocery trips just got 30% faster and 100% less frustrating.
Things we learned from the thing:
AI is best at what humans find tedious. Organizing items by store section is something we all know we should do, but rarely take the time for. AI excels at these tedious-but-valuable tasks. The most useful AI applications aren’t always the flashiest—they’re the ones that remove small frustrations from daily life.
Model selection matters. Not all AI models are created equal. We tested multiple options including various OpenAI GPT and Claude models and to see which performed best with handwritten text. Some were terrible, some were great but really expensive. OpenAI’s gpt-4o model proved more efficient and cost-effective for this specific application.
PWAs are great! We made it a Progressive Web App so you can add it right to you homescreen like any other native app. Turning a web app into a PWA just takes a few extra files, so why not?
Loading times can make or break an app. We quickly discovered image upload and processing was taking too long. Users won’t wait around for a grocery list app. This forced us to optimize aggressively, finding the balance between AI processing power and performance speed.
Handcart taught us that the practical AI applications often solve everyday problems we’ve just accepted as normal.
Maybe the real magic of AI isn’t flying cars, but simply making sure you never have to circle back to the cereal aisle after you’ve already filled your cart with frozen goods.
