The life OS your AI can run
Tasks, notes, boards, money, habits, and family — finally in one calm place. It works without internet, keeps your data yours, and your AI assistant can pitch in with the organizing.
The Margin is a personal productivity web app for organizing your tasks, notes, budgets, habits, and family life in one place. It works offline. Connecting Google Sheets is optional: when you do, The Margin requests access only to the specific spreadsheet you choose, solely to two-way sync it with your board — it never browses your Drive or other files. Read how we use your data in our Privacy Policy.

The lineage
Kept the ritual. Lost the friction.
For centuries, well-run lives lived in the margins — ledgers, journals, tally marks. The Margin keeps that ritual, and gives it a memory, a sync engine, and an assistant to do the carrying.
Tuesday — week 32, 1924
- post the letters
- morning run — 12 days
- groceries ······· $1.40
- read before bed, ½ hour
— copied over from Monday, again
Then: the ritual — rewritten every week, lost every move.

MCP-native
Your AI finally sees the whole picture
For the technical reader: The Margin speaks MCP natively — 166 tools spanning tasks, notes, money, habits, and family. Point Claude Desktop, Cursor, or your own agent at it and it can read and run your whole system.

Today & Planner
Your week on one calm page — synced from boards and Google Calendar.
Whiteboards
Infinite canvas for thinking out loud — sketches included.
Family
Chores, allowances, and a house cup the kids actually care about.
…and the connective tissue
Global search, templates, checklists, Sheets sync, automations, and an app that installs anywhere.
Proof
Zero mockups on this page
These are production screenshots of a real workspace — and they follow the theme toggle up top, because the app really wears both.

Local-first
Airplane-proof by architecture
The Margin keeps a real copy of your life on your device. Everything opens instantly — no spinners, no "reconnecting…". Lose signal on a plane or a train and keep working; it all syncs the moment you're back.
- Your data lives on your device first — the cloud is a backup, not a gatekeeper.
- Changes made offline queue up quietly and sync themselves — nothing is ever lost.
- Your data is exportable any time — and the local copy on your device is always yours.
Back online — queue flushed in 0.3s.
Craft
Every mood. One system.
Four light, four dark — hand-built themes with their own typography, motion, and light, not a color swap. This page is wearing Daybreak right now; the toggle up top flips it.

Daybreak
Warm paper, copper ink, and soft morning light — the study at sunrise
Shorelight
Sea-mist white and deep slate ink with sea-glass light — the coast at morning
Matinee
Beige-box retro computing — aged plastic, phosphor orange, terminal type
Atelier
Porcelain gallery light, graphite ink, and a single vermilion accent — the studio at noon
Midnight Library
Warm Dark Academia — candlelight glow, film grain, leather and wood
Abyssal Calm
Deep Ocean — bioluminescent glow, caustic light, floating particles
VOID_SIGNAL
Glitch / CRT — scan lines, chromatic aberration, corrupted data
