An AI diet planner builds a meal plan for you from your goals, diet type and preferences, usually with recipes and a shopping list. That's different from a tracker, which counts what you've already eaten. Nine apps follow in no particular order, described from each vendor's own page, with planners and trackers both included.
Deciding what to eat every day is the part of healthy eating most people give up on. AI meal planners take that job off you: tell them how you eat and what you're aiming for, and they hand back a week of meals and the list to shop for them.
The nine below are listed alphabetically and in no particular order. Every description comes from each vendor's own website, read as of Oct 2026. Nothing here is medical advice, and I'll say when an app is the wrong tool and a dietitian is the right one.
AI diet planners and trackers at a glance
I checked the free plan column on each vendor's own website, as of Oct 2026. Yes means the page names a free plan, a free version or a free allowance, or calls the product free. Trial only means the page names a time-limited free trial. Not stated means the page I read named neither, so check the vendor's own site before you sign up.

Nine AI apps for planning and tracking meals
ChefGPT
Best for: Planning a whole week of meals around your preferences and dietary needs, with photo-based calorie logging in the same app.
Cronometer
Best for: Detail-minded trackers who want to see which vitamins and minerals they get most and least of, from lab-analysed nutrition data.
Eat This Much
Best for: Putting meal planning on autopilot, with personalised plans for your tastes and schedule and diets such as keto, vegan and Mediterranean.
Fooducate
Best for: Shoppers who want every nutrition detail and ingredient of a product explained, plus a supportive community for motivation.
MacroFactor
Best for: Macro trackers who want the app to act as a diet coach, with calculators for calories, bulking and cutting.
Nutrisense
Best for: People who want round-the-clock glucose data and video calls with a specialised dietitian rather than an automatic plan.
PlanEat
Best for: Anyone with a plan from a dietitian, as it imports a PDF or photo and turns it into daily meals, macros and grocery lists.
Prospre
Best for: Entering calorie, protein, fat and carb targets and getting an instant personalised plan, with normal, vegetarian and vegan options.
Yazio
Best for: Photo-first logging, with AI photo tracking for calories and nutrition plus an intermittent fasting tracker in one app.
One well-known meal planner is closing
Before anything else: Mealime, a meal planning app that's appeared on plenty of lists, now carries a notice on its own home page saying it will shut down. That's why it isn't on this one. If you've been using it, save your recipes and shopping lists while you still can, and treat any list that still includes it as out of date.

Planners build the week, trackers count it
The apps here split into two jobs. AI meal planners take your targets and preferences and produce the week's meals and a shopping list for you. Trackers work the other way round: you log what you ate and they show the calories, macros or nutrients. Some apps now do a bit of both, but they still lean one way.
- Choose a planner if deciding what to eat is the hard part. You'll get a menu, recipes and a grocery list in minutes.
- Choose a tracker if you already cook and want to see what's in it, or you're working to numbers from a coach.
- Choose a dietitian-led app if you have a medical condition or a plan from a professional. Software can make a plan easier to follow, but it can't replace that advice.
What to check in an AI diet planner
- Diet types. Make sure it supports how you eat, whether that's vegetarian, vegan, keto or Mediterranean.
- Allergies and dislikes. A plan you won't eat isn't a plan.
- Shopping lists. The time saving comes from a list that matches the week's meals.
- Grocery delivery. Some planners send the list to a delivery service; one here names Instacart and AmazonFresh.
- Where the numbers come from. Look for nutrition data the app explains, such as a lab-analysed food database.
If you'd rather plan with prompts, my set of ChatGPT prompts for meal prep and a weekly shopping list does a similar job in a chat window.
A word on health claims
Diet apps make big promises in their headlines. Read them as marketing. If you're pregnant, managing diabetes, recovering from an eating disorder or on medication, speak to your GP or a registered dietitian before you follow any app's plan.

My plain advice on AI diet planners
If planning is what defeats you, start with an AI meal planner, set your diet type and dislikes, and use it for one week before you commit. If you already know what you eat and want the numbers, a tracker is the better tool. And if a professional has given you a plan, use an app that follows their plan rather than one that writes a new one.

It's an app that builds a meal plan for you from your goals, diet type and preferences, usually with recipes and a shopping list.
