Real prices, refreshed every morning
Four Barcelona chains get scraped nightly, around 12,700 products, with full price history, promo flags and stock status. When a price moves we keep both numbers.

Eat well on
what you actually
have.
Tell BudgetFork your budget, how many days, and what's already in the fridge. You get back a meal plan, a shopping list split by supermarket, and a total built from the prices those shops are charging today.

The gap
Recipe apps don't know
what anything costs.
They'll hand you a beautiful week of food and no idea whether it costs €40 or €140. Meanwhile the same chicken breast can differ by 60% between two shops four streets apart, and half of what you need is already sitting in your fridge.
BudgetFork starts from the other end, with the money. It reads the shelf, it counts your pantry, and it does the arithmetic in code, so the number on screen is the number you pay at the till.

How it works
Tell it once,
then go shopping.
-
01
Say it like you'd say it to a person
“I've got €50 for three days, just me, breakfast and a late lunch. I like chicken and pasta. There's eggs, cheese and ham in the fridge.” There are no forms to fill in and nothing to configure first.
-
02
It shops the whole city at once
Every ingredient gets matched to a real product on a real shelf at each supermarket, then priced from data scraped that morning. Anything already in your kitchen drops to zero.
-
03
You get a plan and a shopping list
Meals for each day, the list grouped by shop, and what every serving cost you. If day two looks wrong, say so and it plans again inside the same budget.
The conversation
It can ask you
a question back.
BudgetFork holds a real conversation. It can ask you something, let you ask something back, take a detour into “hang on, what's olive oil going for?”, then pick the plan up where it left off.
- Handles a price question mid-plan without losing the thread
- Custom meal slots: ask for breakfast and a late lunch, get exactly that
- Off-topic questions get a fixed refusal. It won't be talked into anything.
The model reads your sentence and writes the reply. Everything in between, the matching and the pricing and the sums, runs as ordinary code.
Under the hood
The parts that
have to be right.
The totals come out of code
The language model reads your request and writes the reply around the result. Matching, pricing, pantry discounts and the budget arithmetic all happen in plain Go, where they can be tested.
Speaks your language, shops in theirs
Ask in English, French or German. Ingredients resolve across languages into Spanish shelf products through a multilingual embedding index.
Knows your neighbourhood
Give it a postal code or just “Gràcia”. Regional stock zones are filtered to what's genuinely available near you.
Your fridge counts
Pantry items match at ingredient level, so “ham” never quietly covers chorizo. They come off at the end, which keeps the plan honest about what you still have to buy.
Split by shop, on purpose
Every ingredient is priced at every shop that stocks it, and the total comes back broken down per store, so you can judge whether the second stop is worth the walk. A promoted product is labelled as one and never removes a cheaper option from the comparison.
Not locked to one model provider
Postgres with pgvector, a Go API, and an LLM endpoint that points at a hosted provider or at Ollama on the same machine. Development runs entirely local; production uses whichever backend answers fastest.

Coverage
Barcelona now.
Your city is a scraper away.
Adding a store means writing one scraper and setting a language and a currency. The planner, the matching and the budgeting logic stay exactly as they are when the city changes. Madrid, Lisbon, Berlin and Belgrade are next in line.

Questions
The obvious ones.
Is this live yet?
Not publicly. The scrapers, the price database, the matching pipeline and the planning API all work today. What's left is the front end and somewhere to host it. People on the waitlist get keys first.
How accurate are the prices?
They're the shelf prices each chain publishes, re-scraped daily, with the full history kept. Where a store prices by region we hold every zone separately and filter down to your area. Nothing gets averaged.
Can the AI get the total wrong?
The total never passes through the model. The language model reads your request and writes the sentence around the answer. The plan itself, meaning which product from which shop in what quantity, gets computed in Go and checked against the database.
What about dietary needs?
Vegetarian, vegan, gluten-free and allergen exclusions are proper inputs rather than a filter bolted on at the end. Telling it what you like also pulls the plan toward food you'll actually eat instead of the cheapest available calories.
Do you sell my shopping list?
No. Nothing that identifies you leaves the system. What a supermarket can buy is demand data pooled across everyone using BudgetFork, meaning what people are planning to cook and how a basket shifts when a price moves. Your individual list is not in it.
Then who pays for it?
The supermarkets, in three ways: that aggregate demand data, a fee when a plan sends a basket their way, and promoted products, where a brand can be put forward as an option for a recipe.
That last one has a hard limit worth stating plainly. A promotion can suggest a product. It can never hide a cheaper one, and it never removes a shop from the price comparison. You always see what everything costs everywhere, and anything promoted says so.
Will there be an API?
There already is one. Chat, price queries, recipe search and streaming budget plans, with API keys and rate limiting. It opens up alongside the app.
