Shopping Lists
One shop, without blurring everyone's boundaries.
CoExyst separates the shared House List from each person's private My List, so groceries, supplies, and personal errands can live in one shopping flow without becoming everyone's business.
Shopping Lists
Shopping is a perfect example of the CoExyst philosophy: shared when it belongs to the house, private when it belongs to the person.
What it helps with
Track common supplies like toilet paper, dish soap, milk, and pantry staples.
Keep personal groceries and errands private.
Claim shared items before a shop so the house can see what is covered.
How it works
Practical coordination, kept close to the part of the house it belongs to.
My List
For personal groceries, errands, and private items. Nobody else in the house sees what belongs only to you.
Claim what you'll buy
Take responsibility for shared items so the house can see what is covered and what still needs attention.
One practical shop
Shared items you take on can sit beside your own private shopping flow, so you can do one real-world shop without exposing your personal list.
Import instead of rewriting
Paste or upload list text from notes, messages, reminders, or another list, then choose whether the items belong in My List or the House List.
Why it matters
The house gets clarity on shared supplies without turning private shopping into household information.
Bring the house into one calmer system.
Everything included. Choose by house size.
