Planet4.MeA productivity app for scatterbrained people.

Notes, tasks, questions, dates, people — write them down wherever you are and they show up where they belong. Groceries too — it learns what you buy and how often, and puts things back on the list before you run out. Works on every device. Sign in with Google and you're in.

Get started

How notes work

🛒
A list that learns
Milk, coffee, dog food — the things you buy on a rhythm come back on the list at about the right time, learned from your own check-offs. When it isn't sure, it stays quiet.
Lists and regulars
📝
Notes that do things
A page of plain text. A few words at the start of a line — todo, ask, @name, a date in brackets, #tag — make to-dos, questions, people, calendar entries and tags.
Notes
✅
To-dos, filed where they belong
One-shot commitments in groups, repeating when they should, and somebody's whenever their text names them. Finished ones wait on a Done shelf in case you need one back.
To-dos
📅
A calendar with nothing to fill in
Every note and to-do that names a day is on that day. A day that has passed stays exactly as it was — nothing is ever marked late.
Calendar
🏠
One household, every phone
Share one invite link. Everyone sees the same lists, to-dos and notes, and it all works without signal — in the shop, in the basement, on the train.
Households and workspaces
✦
An assistant that helps, never decides
Ask it to add to a list, make a to-do, start a note, read a receipt or a pantry shelf from a photo, or explain the app. It never removes or checks anything off.

How it works, in one minute

Sign in with Google. Tap Sign in above. That is the whole sign-up: no password, nothing to verify. Signing in gives you a household of your own, ready to use.
Share one link. From Settings, start a shared workspace and send its invite link to the household. Anyone who opens it and signs in is in, on their own phone, seeing the same lists, to-dos and notes.
Type what you need. Grocery and Household are the two shopping lists. Typing a thing adds it; tapping its box at the shop checks it off. Signal or not — everything is saved on the phone first and syncs when it can.
Let it learn. The things you buy on a rhythm become regulars. The app learns each one's rhythm from your own check-offs and puts it back on the list at about the right time. When it is not sure, it stays quiet rather than guessing out loud.
Write everything else down as it comes. A note is a page of plain text, and a few markers at the start of a line do work for you: todo makes a to-do, ask @sam: asks Sam a question, @name makes a person, a date in square brackets lands on the calendar, #tag files it. Nothing is required; a note with none of them is just a note.
Ask the assistant. When the assisted features are on, an assistant floats over every screen. It can add to a list, make a to-do, start or rewrite a note, read a receipt or a pantry shelf from a photo, and answer questions about the app itself.

Two things it will never do

Mark anything late. A date can pass with something still open, and it stays exactly where it was, in the same quiet voice as everything else. No red, no badges, no overdue pile. The date is a fact; the guilt was the design flaw.

Guess loudly. The list learns from your household's own purchases and only acts when it is confident. A hunch goes on a small "Might be missing" shelf under the list, with its reason, where you can take it or leave it.
