Every Sunday night, the same question comes back around: what are we eating this week? You open the fridge, jot down two or three ideas, forget half the ingredients at the supermarket, and by Wednesday you end up ordering a pizza. Artificial intelligence solves this headache in a few minutes. You give it the number of people, your constraints (time, budget, allergies), and it hands you seven balanced dinners with a grocery list sorted by aisle.
In this guide, you'll discover three practical ways to build your weekly meal plan and an automatic grocery list: first with Skilzy's AI Lab, then with a free assistant like ChatGPT, and finally with dedicated meal-planning apps. Each method is explained step by step, with the exact prompt to copy. You don't need any technical skills — just the ability to write down what you want to eat.
Why plan your weekly meals with AI?
Planning your meals with AI saves time and money and cuts down on waste: in a single request, you get balanced menus and a complete grocery list, instead of improvising every night. It's the difference between thirty minutes of thinking spread across the week and five minutes done once and for all.
Food waste is a real expense. According to ADEME, each person in France throws away nearly 30 kg of food per year on average, part of which comes from poorly planned purchases. When you head to the supermarket with a precise list built around recipes you'll actually cook, you buy less and throw away less.
AI also helps you add variety and balance. You can ask it to rotate meat, fish, legumes, and vegetarian dishes, following the broad principles of the official nutrition guidelines from the Manger Bouger program. In short: you delegate the tiring part (coming up with ideas, making the list) and keep the fun of cooking.
Method 1: Generate your menus and grocery list with Skilzy's AI Lab
The simplest way to build your menus and grocery list is Skilzy's AI Lab: you pick a guided agent, answer two or three questions, and it writes everything for you. No blank page, no prompt to dream up — the tool asks you the right questions in the right order.
In the AI Lab, go to the Home tab, then the Guided section. There you'll find a catalog of mini agents, each designed for a specific task. You pick one, it asks for the number of people, your constraints, and your preferences, then it hands back a complete menu and its grocery list.
The advantage of the Lab is that you use real AI tools directly inside the platform, with credits included, without stacking up subscriptions. Skilzy is a French platform for learning and using AI in everyday life, and organizing your meals is just one example of what you can automate once you get the hang of it. If you want to see everything it covers, take a look at the different Skilzy programs: writing, images, automation, and plenty of other practical uses.
Good news if you just want to try it out: you can test it without a credit card. The discovery demo gives you 7 days with 1 image, 1 video, 1 song, and 10 messages. That's more than enough to generate a first weekly menu and get a feel for it. You simply need to create an account — no card required.
Method 2: Use a free AI assistant like ChatGPT
A free AI assistant like ChatGPT does the job too: you open a conversation, paste your prompt, and get your menus back in a single response. It's the all-purpose solution, handy if you already use the tool for something else.
The steps are simple. You open a new conversation, write your request (you'll find a complete prompt template further down in this article), and get seven dinners with the ingredient list. If a dish doesn't appeal to you, you reply “replace Thursday with a vegetarian dish” and the AI corrects only that line.
Two limitations to keep in mind. First, the free version can be slower or capped during peak hours. Second, if you're a beginner, writing a good prompt on the first try isn't obvious — which is exactly what a guided agent does for you. If you've never used the tool, start with our guide on how to use ChatGPT when you're a beginner; it'll save you time.
Method 3: Dedicated meal-planning apps
Specialized apps like Jow, Frigo Magic, or Mealime offer ready-made menus and generate a grocery list linked to delivery. They're useful if you want a catalog of already-photographed recipes and a cart that fills itself at your supermarket.
Their strength is integration. You choose your dishes, the app calculates quantities based on the number of people, and it sends the list straight to an online grocery service. Some even read the contents of your fridge to suggest anti-waste recipes.
Their limitations, on the other hand, are real. You're locked into the app's catalog: it's hard to break away from a specific recipe or impose an unusual constraint (a very tight budget, a special diet, an ingredient you need to use up). Many also run on a separate subscription, and some features are reserved for the paid version. A general-purpose AI assistant stays more flexible: you talk to it in your own words, and it adapts.
The right prompt for a successful weekly menu
A good prompt for a weekly menu fits in one precise sentence: number of people, days involved, budget, dietary constraints, and prep time. The clearer you are, the better the result. Here's a template to copy and adapt:
Build a menu for the 7 dinners of the week for 2 adults and 2 children. Budget of around 70 euros. No pork, at least one vegetarian dish. Each recipe should take less than 30 minutes to prepare. At the end, add the complete grocery list, with quantities, sorted by aisle (produce, fresh goods, pantry, frozen).
A few tweaks that make all the difference:
- Specify the time you have: “less than 20 minutes on weekdays, a longer dish on the weekend.”
- Mention what you already have: “I have zucchini and rice to use up.”
- Ask for it sorted by aisle: your list becomes usable as-is at the supermarket.
- Add a variety constraint: “no repeating the same starch twice in the week.”
Knowing how to phrase this kind of request is a skill that will serve you everywhere. If the topic interests you, our guide to learning AI as a beginner covers the basics of writing clear instructions.
Adapting the menus to your family and budget
AI adapts the menus to your situation in a few seconds: allergies, a tight budget, picky kids, or express meals — you just have to say so in your request. You don't get a generic menu, but a plan designed for your household.
A few concrete cases. Tight budget? Ask for a “menu under 50 euros for the week, leaning on legumes and seasonal vegetables.” Kids who turn their nose up at vegetables? Specify “recipes kids will like, with the vegetables built into the dish rather than on the side.” Something came up on Tuesday? Reply “on Tuesday I get home late, suggest a dish under 15 minutes” and the AI recalculates just that day.
This delegation logic applies to your whole family routine. The same reflex (give clear context, let the AI suggest, adjust) works, for example, when you want to help your child with homework without handing them the answers. Once you've grasped the principle with meals, you'll reuse it all week long.
Conclusion
Planning your meals and grocery list shouldn't cost you your Sunday evening anymore. With a guided agent from Skilzy's AI Lab, you get a balanced menu and an aisle-sorted list in five minutes, without knowing how to write a single prompt. A free assistant or a dedicated app do the job too, each with its own limits. The easiest thing is to test it: Skilzy's discovery demo lets you try it without a credit card, just long enough to generate your first menu and see whether the time saved wins you over.
