The photo-of-the-fridge trick is one of the most quietly useful things any chatbot will do for you, and it has changed how I shop. Pulling a scattered pile of recipes into a single place that you can ask questions of is a one-afternoon job. The ongoing tracking is a bit harder than the marketing suggests, and the honest answer there is to keep it simple.

The photo-to-dinner moment

Open Claude, ChatGPT, or Gemini on your phone. Take a photo of the open fridge. Then send the photo with the prompt below.

Here's what's in my fridge. I also have these pantry staples not in
the photo: [rice, pasta, olive oil, tinned tomatoes, soy sauce,
flour — fill in your own].

I'm cooking dinner for [number] people tonight. I have about
[40 minutes / an hour]. I [am / am not] willing to do a quick stop
at the supermarket on the way home.

Please:
1. List what you can see in the photo. If you're not sure about
   something, say so — don't guess.
2. Suggest 5 specific dinners I could make tonight. Give me real
   quantities, not vague guidance.
3. Flag anything in the photo that looks like it needs eating
   today (open packages, cut vegetables, leftovers).
4. For each dinner, list any extras I'd need and roughly what
   they'd cost at a supermarket in [your suburb].

Diet notes: [vegetarian / no pork / dairy-free / nothing too spicy
for the kids — fill in].

The answer will be specific recipes with quantities, not generic suggestions. There is a fuller walk-through of this on the Build a Meal Planner page, which started from exactly this scenario.

Building a recipe collection

For ongoing recipe storage, set up a ChatGPT Custom GPT or a Claude Project. Upload your favourite recipes (PDFs, photos of cookbook pages, or just typed notes), tag them by cuisine and difficulty, and ask it to help you cook them, scale them, or substitute ingredients. The first set-up takes an afternoon. Once it is done, "what can I cook tonight from those recipes that uses what I have on hand" becomes a one-line question. NotebookLM works for the same purpose and is free, although it is less good at the active "help me cook this" part of the job.

Tracking what is actually in the fridge

Be honest with yourself before going down this rabbit hole. Genuine fridge inventory needs you to log every shop and tick things off as you cook them, and most people will not stick to that for more than a fortnight. The dedicated apps that try this (Whisk, SuperCook, Mealime) all have decent free tiers and are worth a quick look, but I have not met anyone who keeps their fridge state perfectly current in one. The pragmatic version is a photo of the fridge once a week before the shop, a photo of the receipt after, and the chatbot keeping the rough running list. Less precise than a real database, but it is the version you will actually use.

If you want to go further

This site has a tutorial for building your own meal-planner web app without writing code, using Bolt.new. That gives you a shopping list grouped by supermarket section, the ability to swap meals, and a fridge-photo upload step that the standard apps do not handle as well as a chatbot.

The same trick on the liquor cabinet

Once dinner is on the table, point the phone at the bottles on the shelf and ask "based on these, plus ice and the basics from the fridge, what cocktails can I make? Give me three with full ratios and the method." You will get classics that match what is actually on the shelf rather than a generic list. This version of the trick is more reliable than the fridge photo for one straightforward reason. Every bottle is labelled. The AI is reading writing on a label, not guessing what might be in a half-used jar at the back of the second shelf. Identification errors drop close to zero. Sense-check the ratios before pouring, but you do not have to wonder whether the AI thought a bottle of soy sauce was something else.

What I would not do

The chatbots are good at recognising obvious items in a fridge photo, but they make mistakes. Half-empty jars at the back, leftovers in a takeaway container, anything in a sealed box. The AI will sometimes invent what is in there, or miss it entirely. Always read the recipe back before you start cooking and ask "did you actually see all of these in the photo, or did you assume?". For anything to do with allergies or strict dietary requirements, do not rely on the AI's identification at all. Read the labels yourself.

The other thing to avoid is paying for a premium recipe app on day one. The free tiers of all the main chatbots do this job well enough that you can wait a month before deciding whether you want a dedicated tool, a Custom GPT, or just the photo-and-ask habit. Most people end up using the photo-and-ask habit and nothing else.

The thing the cooking question is really asking

The fridge photo and the recipe library are useful in their own right. The bigger thing they unlock, once they are running together, is the smaller domestic decisions stop being decisions. What is for dinner is the most-asked question in any household. Most of the energy that question takes is not in the cooking. It is in the choosing. The photo plus the running list of recipes you actually like reduces the choosing to a thirty-second conversation, and gives you back the half-hour the choosing was costing you. That is not a culinary improvement. It is a decision-fatigue improvement, and it is worth more than the cocktails.
