By Sunday afternoon, you have a fridge, a half-empty pantry, and no plan — so the default becomes takeout again. Perplexity, the AI search assistant at perplexity.ai, can take a few details about your household and spit out a realistic week of meals, then turn those meals into a single grouped shopping list. This guide walks you through the whole thing in about ten minutes.
💡 Tip: tap a step’s number when you finish it — a green tick appears and your browser remembers how far you got.
- A free Perplexity account (you can also use it without signing in, but a free account keeps your plan saved across devices).
- A phone or a computer with a browser — the website works fine on both.
- Roughly 10 minutes the first time; about 2 minutes once you get the hang of it.
Open Perplexity and start a new thread
In your browser, go to perplexity.ai. You'll see a clean page with a single search bar in the middle and a small + New Thread or Focus selector near it. Click the bar once so your cursor is inside it. If you're on the Perplexity mobile app, the same field sits at the top of the home screen under the word "Ask". A new conversation opens so Perplexity's answer won't get mixed up with anything else you ask later. 💬 Example: you don't need to type anything yet, just confirm the field is active (you should see a blinking cursor).
**** the layout has changed over time, so look for a wide text field labeled "Ask anything" or a pencil/compose icon — they all do the same thing.
the field looks ready for typing and there's a small arrow or send icon on the right side.
Describe your week in one short prompt
Now type a single, clear message that explains your household, your dietary needs, and how much cooking you want to do. The more concrete you are, the better the plan — vague prompts produce vague meals. Perplexity will pull ideas from cooking sites and write back a full week with breakfast, lunch, and dinner (or just dinner if you say so). 💬 Example: "Plan dinners for 7 days for 2 adults. One person is vegetarian, the other eats everything. We have about 30 minutes to cook on weeknights and an hour on Sunday.
**** if the answer comes back with too much text or feels generic, scroll up and click the small + New Thread button to start fresh — old messages don't carry over, which is exactly what you want when you're refining a plan.
We already have olive oil, salt, pepper, garlic, onions, and rice in the pantry." You'll know it worked when Perplexity shows a numbered or table-style week of meals, with at least a sentence describing each dish and small footnote-style citations under the answer.
Tweak the plan until it fits your life
Plans from AI are rarely perfect on the first try — and that's fine. Reply in the same conversation (don't start a new one yet) with the specific changes you want. Perplexity keeps the context of your previous request, so it can swap a single dinner, repeat a leftover night, or move a recipe to a different day. Treat this like texting a friend who's helping you plan: short, polite, specific. 💬 Example: "Replace Friday's salmon with a chicken dish — one of us doesn't eat fish.
**** if the conversation starts drifting off-topic, click + New Thread and paste your original prompt plus the tweaks into a fresh message — context windows (the amount of text the AI can "remember" in one chat) have limits, and a clean start often gives a cleaner plan.
Also, add a 'leftovers / eat out' night somewhere mid-week so I don't cook 7 nights straight." You'll know it worked when the updated plan shows your changes clearly and the rest of the week still makes sense around them.
Turn the plan into one grouped shopping list
Once you're happy with the meals, ask Perplexity to convert them into a single shopping list, grouped the way a real store is laid out. This is the step most people skip — and the one that saves the most time at the supermarket. You'll get a tidy list with categories like produce, dairy, pantry, and protein, plus rough amounts you can adjust. 💬 Example: "Turn this 7-day meal plan into one grocery list grouped by store section (produce, dairy, meat, pantry, frozen).
**** if Perplexity gives you one long flat list, just reply and say "Please regroup this by store section, like produce, dairy, meat, pantry." If you're on the paid Pro plan, you may see a deeper, more detailed breakdown — but the free version handles this task fine for a normal week.
List the rough quantity for each item and assume I'm cooking for 2 adults." You'll know it worked when you can scroll the answer top-to-bottom and mentally walk through your local store without re-sorting anything in your head.
Save the list somewhere you'll actually see it
The final step is making sure the list leaves Perplexity and lands somewhere useful — your phone's notes app, a shared family note, or a screenshot on your lock screen. Highlight the entire list with your mouse or finger, copy it, then paste it into Notes, Google Keep, Apple Notes, or any shopping-list app you already use. 💬 Example: paste it as-is and add a one-line header like "Week of [date]" so future-you knows which plan this list belongs to.
**** if you can't select text easily, look for a Copy button at the bottom of Perplexity's answer, or use your browser's print-to-PDF option so you have a clean copy on your phone.
you can open the list on your phone, walk into a store, and shop without scrolling back through a long chat.
- Writing a prompt that's too vague. "Plan my dinners" gives you a generic answer. Always include the number of people, dietary needs, time available, and any pantry staples you already own.
- Forgetting to ask for the grouped list. A flat list of 40 ingredients in random order is technically right but useless in a store. Ask explicitly for store-section grouping, and you save ten minutes of aisle-hopping.
- Trusting the quantities blindly. Perplexity suggests amounts, but it doesn't know your portion sizes, your appetite, or whether you already have half a bag of pasta in the cupboard. Glance over the list and edit before you go.
Open perplexity.ai and type: "Plan 3 simple weeknight dinners for 2 adults. We have 30 minutes and pantry basics. Give me the recipes briefly and then a short grouped shopping list." See how the answer feels, then come back and extend it to the full week.
