# Keep a daily journal

A few lines a day, with a mood and energy score. Over months, ADoor, your data account, turns that into something you can ask about: what good weeks had in common, or what you wrote this day last year.

## An example

**You:** Good day. Finished the presentation, lunch with Sam, felt tired by 4. Mood 7, energy 5.

**ADoor:** Added 1 entry to Journal

**Journal**

| Date | Mood | Energy | Entry |
| --- | --- | --- | --- |
| Oct 20 | 7 | 5 | Finished the presentation, lunch with Sam… |

## What you can ask later

- “What were my best weeks this year, and what was going on?”
- “Is my mood lower on days I sleep under seven hours?”
- “When did I last see Sam?”
- “What did I write on this day last year?”
- “Chart my mood and energy for the last two months.”

## Who can see what

- **Only you**. A journal stays in your own space, and only the assistants you connect can read it.
- **One assistant can read it and another can’t.** Connect Claude to your journal and keep the ChatGPT you use for work out of it.

## How it compares with Day One or a notebook

Day One is better for a long-form journal with photos, locations, templates and end-to-end encryption. A paper notebook is better if you never want it on a screen.

ADoor fits a short daily log you want to ask questions of. Mood and energy are numbers, so your assistant can compare them with your sleep or workouts and look back for you.

## How to start

1. Sign in to ADoor, then add it to an assistant like ChatGPT, Claude, Grok or Cursor through MCP.
2. Tell it: “Keep a journal for me: date, mood out of 10, energy out of 10, and the entry.”
3. Write two or three lines each evening, with a mood and energy score.
