The Complete Guide to MealThinker

Everything you need to go from 'what's for dinner?' to eating well, on autopilot.

Getting Started (Your First 5 Minutes)

MealThinker gets smarter the more it knows about you. Spending 5 minutes on setup means every future suggestion is already personalized - no repeating yourself.

MealThinker onboarding - dietary preferences selection
MealThinker onboarding - goals and allergies

Complete Your Onboarding

When you first sign up, you'll walk through a quick setup: dietary preferences (vegan, keto, gluten-free, etc.), allergies, and health goals. Don't skip this - it's the foundation for every suggestion you'll get.

Set Your Cooking Profile

In Preferences, set your cooking skill level, time per meal, budget, and household size. This tells MealThinker whether to suggest quick 15-minute meals or elaborate weekend projects.

Add Your Favorite Cuisines

Pick up to 10 cuisines you love - Italian, Mexican, Thai, Indian, and more. MealThinker uses these to vary your suggestions so you're not eating the same style every day.

Set (or Auto-Calculate) Your Nutrition Targets

Enter your age, weight, height, and activity level, and MealThinker calculates your daily calorie and macro targets automatically. You can also set custom targets if you have specific goals.

List Your Disliked Foods

Hate cilantro? Can't stand mushrooms? Add them to your disliked foods list and MealThinker will never suggest them. Saves you from typing 'no mushrooms' every single time.

Pro Tip

The more preferences you set upfront, the less you need to type later. MealThinker uses ALL of this context every time you ask for a meal.

Pro Tip

You can always update preferences later. Check your About Me page to see everything MealThinker knows about you.

The AI Chat (Your Meal Planning Brain)

The chat is where the magic happens. Ask for a single meal, a full day's plan, cooking advice, or help using up ingredients. Here's how to get the most out of it.

MealThinker AI chat with quick action buttons

Quick Actions

Tap any quick action button to instantly start a request. These are the 7 most common things users ask for:

  • Plan My Day - Get breakfast, lunch, and dinner suggestions for today
  • Just Dinner - Only need tonight's meal? Start here
  • Just Breakfast - Morning meal suggestions
  • Just Lunch - Midday meal ideas
  • How Do I Cook... - Fill in any ingredient or dish for cooking guidance
  • What Can I Make With My Pantry? - Uses your actual pantry inventory
  • What's Expiring Soon? - Shows pantry items about to go bad

Serving Sizes & Leftovers

Before sending a quick action, you can set the number of servings (1-12 people) and toggle 'Make extra for leftovers' on or off. MealThinker adjusts portions and nutrition accordingly.

Natural Language - Just Ask

You're not limited to quick actions. Type anything in plain language:

Plan dinner for 4 using the tofu in my fridge
I see you have tofu in your pantry. Here are 3 dinner options for 4 people...
I need a high-protein lunch under 30 minutes
Based on your goal of building muscle and your 30-min time limit, here are some options...
What can I make that uses up the spinach before it goes bad?
Your spinach expires in 2 days. Here are 3 recipes that use it up...

Refine in Conversation

The chat remembers your conversation for 24 hours (last 20 messages). You can refine suggestions without starting over:

  • 'Actually, make that vegan' - switches the suggestion
  • 'Can you add more protein?' - adjusts the recipe
  • 'What about something with my air fryer?' - factors in equipment
  • 'Give me the full recipe for option 2' - expands a suggestion into a complete recipe

Pro Tip

Use 'What's Expiring' before your weekly grocery run to use up what you have first.

Pro Tip

Mention specific equipment for targeted results: 'Air fryer dinner under 20 minutes' or 'Instant Pot meal prep for the week.'

Pro Tip

The AI gives you 2-3 meal options first, then you ask for the full recipe of whichever you like. This saves time vs. getting a full recipe you don't want.

Your Pantry (Stop Wasting Food)

Your pantry is MealThinker's secret weapon. When the AI knows what you have, it suggests meals using those ingredients - reducing food waste and saving you money.

Adding Items

There are two ways to add items:

  • In the Pantry tab - tap '+' and type the item. MealThinker auto-categorizes it (Produce, Grains, Frozen, Canned Goods, etc.) and estimates its shelf life.
  • In the Chat - tell the AI 'I just bought tomatoes, tofu, rice, and broccoli' and it adds them to your pantry automatically.
  • Bulk Import - use the 'Import Common Staples' button to quickly add pantry basics like salt, pepper, olive oil, garlic, etc.

Expiration Tracking

MealThinker automatically estimates shelf life for every item. You'll see visual warnings:

  • Green - fresh, plenty of time
  • 'USE SOON!' - expires within 3 days, highlighted in orange
  • 'EXPIRED' - past the use-by date, flagged in red with how many days ago

Your dashboard also shows a count of items expiring within 3 days, with specific item names.

Running Low Flags

Mark any item as 'running low' and MealThinker factors this into suggestions - it'll prioritize using that ingredient before suggesting you buy more.

Pantry-Aware Suggestions

When you ask 'What can I make with what's in my pantry?' the AI checks your actual inventory and suggests recipes using those specific ingredients. It also factors in what's expiring soonest.

Pro Tip

After grocery shopping, just tell the chat 'I bought...' and list everything. It adds them all to your pantry with auto-categorization and shelf life estimates.

Pro Tip

Mark items as 'running low' so MealThinker prioritizes using them up before suggesting you buy more.

Pro Tip

Check the 'What's Expiring' quick action weekly - it's the fastest way to reduce food waste.

Single Meals

Use 'Just Dinner,' 'Just Breakfast,' or 'Just Lunch' for a quick single-meal suggestion. Great for when you only need help with one meal.

Full Day Plans

Use 'Plan My Day' to get breakfast, lunch, and dinner suggestions that hit your daily nutrition targets together. The AI balances macros across all three meals.

Weekly Plans

Ask 'Plan my meals for the week' and MealThinker creates a 7-day plan with variety across cuisines, proteins, and cooking methods. No repeating the same meal twice.

Saving & Reusing Plans

Save any plan with a custom name (e.g., 'Busy Work Week' or 'Holiday Prep'). Browse saved plans anytime in the Meal Plans tab.

Swapping Meals

Don't like one meal in your plan? Swap just that one - the rest stays. MealThinker suggests alternatives that still fit your nutrition targets.

Generate Shopping Lists

Turn any saved meal plan into a shopping list with one tap. It cross-references your pantry so you only buy what you actually need.

Pro Tip

Start with single-day plans until you find your rhythm. Weekly plans work best once your pantry is stocked and preferences are dialed in.

Pro Tip

Ask for plans that 'use what I have in my pantry' - it checks your actual inventory and reduces your grocery bill.

Recipes (Build Your Personal Collection)

Every recipe MealThinker generates is automatically saved to your library. Over time, you build a personalized cookbook that the AI learns from.

Your Recipe Library

All generated recipes are auto-saved with full details: ingredients, step-by-step instructions, nutrition facts (macros + micros), cook time, and serving count.

Rate Recipes (1-5 Stars)

After cooking a recipe, rate it. Higher-rated recipes influence future suggestions - MealThinker learns what you actually enjoy and suggests similar dishes.

Favorites & Want to Make

Mark recipes as 'Favorite' for quick access to your best ones. Use 'Want to Make' as a cooking bucket list - queue up recipes you're excited to try.

Personal Notes

Add notes to any recipe: 'Kids loved this,' 'Add extra garlic next time,' 'Double the sauce.' Your notes are permanent and show up whenever you view that recipe.

Log as Eaten

Cooked a saved recipe? Tap 'Log as Eaten' to add it to your meal log with all the nutrition data already filled in - no manual entry needed.

Finding Recipes

Browse your library by: all saved, favorites only, want-to-make, top-rated, or most cooked. Find that one recipe you loved last month in seconds.

Pro Tip

Rate every recipe you cook. This is how MealThinker learns your actual taste - not just your dietary preferences, but what you genuinely enjoy eating.

Pro Tip

Use 'Want to Make' as a cooking bucket list. When you're stuck, ask the chat 'pick something from my want-to-make list.'

Pro Tip

Add notes like 'doubled the recipe for meal prep' so future-you remembers what worked.

Shopping Lists (From Plan to Store)

MealThinker organizes your shopping by grocery aisle and only adds what you actually need based on your pantry.

Auto-Categorized by Aisle

Every item is automatically sorted into grocery sections - Produce, Grains, Frozen, Canned Goods, etc. Walk through the store in order, no backtracking.

Generate from Meal Plans

Turn any saved meal plan into a shopping list with one tap. MealThinker cross-references your pantry and only adds ingredients you don't already have.

Smart Suggestions

The Smart Suggestions tab analyzes your dietary preferences, favorite cuisines, and cooking habits to recommend grocery staples you might need - organized by category (proteins, grains, produce, pantry staples).

Check Off as You Shop

Tap items to mark them as purchased. Use the list on your phone while walking through the store.

Pro Tip

Use Smart Suggestions before a grocery run - it catches staples you might have forgotten based on what you usually cook.

Nutrition Tracking (See the Full Picture)

Log what you eat and see how you're tracking against your personalized nutrition targets - daily macros, calories, and micronutrients.

Logging Meals

Log meals in two ways: tap 'Log as Eaten' on a saved recipe (nutrition pre-filled), or manually log any meal with the AI estimating nutrition from your description.

Daily Macro Tracking

See progress bars for calories, protein, carbs, and fat against your daily targets. At a glance, you know if you need more protein at dinner or if you've hit your calorie target.

Micronutrient Tracking

Track fiber, iron, calcium, sodium, vitamin C, and vitamin B12. MealThinker sets targets based on your age, sex, and dietary preferences (e.g., vegans get higher iron targets).

Day-by-Day History

Navigate between dates to see your nutrition history. Spot patterns - maybe you consistently undereat protein on weekdays, or your fiber intake drops on weekends.

AI Fills Nutritional Gaps

MealThinker doesn't just track - it acts on the data. If your logged meals are low on iron, the next meal suggestion will prioritize iron-rich foods automatically.

Pro Tip

Don't obsess over hitting exact macro numbers daily. Focus on protein and calorie targets - let carbs and fat balance naturally.

Pro Tip

Log meals consistently for a week and MealThinker starts filling nutritional gaps in your suggestions automatically.
