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 store, and by Wednesday you end up ordering a pizza. Artificial intelligence solves this headache in just 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 the Skilzy 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 store 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 alternate between meat, fish, legumes and vegetarian dishes, following the main 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 the Skilzy AI Lab

The simplest way to build your menus and grocery list is the Skilzy 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 you the number of people, your constraints and your cravings, then hands you 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 juggling multiple 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 that's covered, take a look at the different Skilzy programs: writing, images, automation, and many 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 one reply. It's the go-to option, handy if you already use the tool for something else.

The process is 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 „swap Thursday for a vegetarian dish" and the AI fixes just that line.

Two limits to keep in mind. First, the free version can be slow or restricted 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 on how to use ChatGPT as 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 strength: integration. You choose your dishes, the app calculates quantities based on the number of diners, and sends the list straight to an online grocery service. Some even read the contents of your fridge to suggest anti-waste recipes.

Their limits, on the other hand, are real. You're locked into the app's catalog: it's hard to step outside a specific recipe or to 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:

Create 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 less than 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 available: „less than 20 minutes on weekdays, a longer dish on the weekend".
  • Give 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 store.
  • Add a variety constraint: „not the same starch twice in one week".

Knowing how to phrase this kind of request is a skill that will serve you everywhere. If the subject interests you, our guide to learning AI as a beginner covers the basics of writing clear instructions.

Adapting menus to your family and budget

AI adapts menus to your situation in seconds: allergies, a reduced budget, picky kids or express meals — you just need to mention 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 who sulk in front of vegetables? Specify „recipes that appeal to children, with the vegetables mixed into the dish rather than served on the side". Something unexpected 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, when helping your child with 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 the Skilzy AI Lab, you get a balanced menu and a list sorted by aisle in five minutes, without writing a single prompt. A free assistant or a dedicated app do the job too, each with its own limits. The easiest thing is to try it: the Skilzy discovery demo lets you test without a credit card, just long enough to generate your first menu and see whether the time savings win you over.
