Every Sunday night, the same question comes back: 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 the grocery list sorted by aisle.
In this guide, you'll discover three concrete 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, saves 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 once and for all.
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 waste less.
AI also helps you vary and balance your meals. You can ask it to alternate meat, fish, legumes and vegetarian dishes, following the broad principles of the official nutritional guidelines from the Manger Bouger program. In short: you delegate the tiring part (coming up with ideas, making the list) and keep the pleasure of cooking.
Method 1: generate your menus and grocery list with Skilzy's AI Lab
The easiest 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 to the Guided section. There you'll find a catalog of mini agents, each designed for a specific task. You pick one, it asks you for the number of people, your constraints and your preferences, then it sends back a complete menu and its grocery list.
The appeal of the Lab is that you use real AI tools directly within the platform, with credits included, without piling up subscriptions. Skilzy is a French platform for learning and using AI day to day, and organizing meals is just one example of what you can automate once you get the hang of it. If you want to see everything that's covered, 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, but no card is 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 in your prompt and get your menus back in a single reply. It's the go-anywhere 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 you get seven dinners with the ingredient list. If a dish doesn't appeal to you, you reply „swap Thursday for a vegetarian dish" and the AI fixes just that line.
Two limitations to keep in mind. First, the free version can be slowed down or capped during peak hours. Second, if you're a beginner, writing a good prompt on the first try isn't obvious: that's exactly what a guided agent does for you. If you've never used the tool, start with our guide how to use ChatGPT when you're a beginner, you'll save 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 advantage: integration. You pick your dishes, the app calculates the quantities based on the number of diners and sends the list straight to an online grocery service. Some even read what's in your fridge to suggest anti-waste recipes.
Their limitations, however, are real. You're locked into the app's catalog: it's hard to step outside a specific recipe or impose an unusual constraint (a very tight budget, a particular diet, an ingredient to use up). Many also work 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 into 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:
Put together a menu for the 7 dinners of the week for 2 adults and 2 children. Budget of about 70 euros. No pork, at least one vegetarian dish. Each recipe must take under 30 minutes to prepare. At the end, add the complete grocery list, with quantities, sorted by aisle (fruits and vegetables, fresh products, pantry, frozen).
A few tweaks that make all the difference:
- Specify the time you have : „under 20 minutes on weekdays, a longer dish on the weekend".
- Say 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 : „not the same starch twice in a 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 menus to your family and your budget
AI adapts menus to your situation in seconds: allergies, tight budget, picky kids or express meals, you just have to specify it 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, favoring legumes and seasonal vegetables". Kids pulling faces at vegetables? Specify „recipes that kids like, with the vegetables built into the dish rather than on the side". Something comes up on Tuesday? Reply „on Tuesday I get home late, suggest a dish under 15 minutes" and the AI recalculates just that day.
This logic of delegation applies to your whole family organization. The same reflex (give clear context, let the AI suggest, adjust) works, for example, to help your child with their homework without giving them the answers. Once you've grasped the principle with meals, you'll reuse it everywhere in your week.
Conclusion
Planning your meals and grocery list should no longer cost you your Sunday evening. With a guided agent from Skilzy's AI Lab, you get a balanced menu and a list sorted by aisle in five minutes, without knowing how to write a single prompt. A free assistant or a dedicated app does the job too, each with its own limitations. The simplest thing is to try it: Skilzy's discovery demo lets you test it without a credit card, just long enough to generate your first menu and see whether the time saved wins you over.
