Show HN: PlanEat AI, an AI iOS app for weekly meal plans and smart grocery lists

1•franklinm1715•1mo ago
Hi HN,

I am Valerii and I have been working on PlanEat AI, an iOS app that builds fully personalized weekly meal plans with a smart grouped grocery list.

The problem I am trying to solve is simple most people who want to eat better do not struggle with nutrition theory, they struggle with the daily questions

what to cook today, how to keep it sustainable, and what to buy for the week.

I tried Instagram and TikTok recipes, ChatGPT prompts, and existing meal planner apps. For me they failed in three places 1. low personalization I hate a bunch of ingredients, my wife hates a different bunch, and apps rarely adapt to that 2. they treat recipes and grocery lists as separate worlds 3. too many perfect recipes that do not fit real life time and local products

What PlanEat AI does now^ - builds a weekly meal plan based on goals, dislikes, available time and basic cooking equipment - generates simple step by step recipes using normal ingredients - creates a smart grocery list that is grouped by store sections and stays in sync with the plan - lets you quickly swap meals and update the list without redoing everything

Under the hood it uses an LLM based planner plus some logic to keep plans realistic in terms of time and number of ingredients. I am still iterating on the trade off between healthy enough and actually doable after work.

I would love feedback from you on - is the onboarding clear enough or does it ask for too much - does the weekly plan view make sense at a glance - what feels most annoying or confusing in the first two minutes of using it

Right now it is iOS only. If you do not want to install the app, there are screenshots and a short explanation on the landing page as well.

We are also launching it on Product Hunt today as a way to collect more early feedback from non technical users. The main reason I am posting here though is to learn what I am missing from a builder point of view.

Thanks for taking a look, I am happy to answer any questions about the product, the tech behind it, or the process of turning a personal diet problem into an app.
