Grocery Shopper Assistant

A quiet sous chef who keeps the list, remembers what's in the pantry, and tells you exactly what to grab on the way home.

The Analogy

Your sous chef with a clipboard.

Picture the best line cook you've ever worked with. They don't just cook. They know the walk-in, they know the prep list, they know what's about to spoil, and they know what Tuesday's menu looks like. When the delivery truck pulls up, they already have the order dialed.

This app is that person, for your kitchen. It tracks what recipes you like, what's sitting in your pantry, and what you're trying to eat this week. Then it builds one consolidated grocery list — no duplicate items, no forgotten staples, no aimless wandering through the bread aisle.

Stop asking "what's for dinner." Start asking "what's already in the fridge, and what's one stop away."
How It Works

Three moves, start to list.

Input
You tell it what you like.
Recipes you save, dietary preferences, what's in the pantry already. Once set, the app remembers — you don't enter it twice.
→
Transform
It does the math.
Matches recipes to your week, cross-references the pantry, merges ingredients across meals so one bag of onions covers three dinners.
→
Output
You get one clean list.
Grouped by store aisle. Sized to what you actually need. Shareable with whoever's doing the run.
Under the Hood

What's actually running.

Front Door Web App A browser-based interface — nothing to install. Works on phone and laptop.
Brain Python Backend Handles the recipe matching, pantry logic, and list building. The decision engine.
Memory Database Stores your recipes, pantry state, and shopping history so nothing resets between sessions.
Home Fly.io Cloud Hosted in a lightweight cloud platform — always on, reachable from any device.
Why it's built this way

A web app means no app store approvals, no device-specific code. The same tool works on a spouse's phone, a roommate's laptop, and a tablet on the fridge. One source of truth, zero friction to share.

Why It Matters

The point isn't groceries.

It's reclaiming the thirty minutes a week you lose to meal-planning guesswork, and the forty dollars a month you waste on double-buying things you already had. Small decisions, made on autopilot, compound into real time and money.

The architecture reflects that philosophy: keep it simple, keep it always-on, keep the decision layer close to the data. Nothing fancy. Just useful.
