Getting started with Fragment

Fragment is a quiet notebook for thinking with AI. You don't need a perfect system on day one. In your first 10 minutes, it's enough to write one Fragment in the demo Studio, give it a simple name and tags, and add a tiny AI config in YAML.

Fragment は「AI と一緒に考えるための、静かなノート」です。 はじめは「本番のノート」を作る必要はなく、サインイン不要のデモ Studio で試すだけで十分です。 Fragment を 1 つ書いて、軽く名前とタグをつけて、AI に伝えたいことを数行だけ添えてみてください。

In the demo Studio, nothing is saved to the server. Close the tab and everything disappears — so you can experiment freely.

A gentle path: create one Fragment → name and tag it → add one tiny AI setting. You can learn the deeper structure later in the docs.

Step 1

Make one small Fragment.

Start by creating just one Fragment in the demo Studio. Don't worry about structure or quality. The goal is simply to have one place that holds how things feel today.

まずは Fragment を1 件だけ作ります。きれいにまとめる必要はありません。「今日の自分の状態が 1 か所に置かれている」ことを優先してください。 デモ Studio では、閉じれば内容はサーバーに残りません。

Journal — today’s note

Write a short note about what happened today, how you felt, and any small insights.

Project — current focus

Capture the work, study, or personal project that is on your mind right now.

Request — how you want AI to help

Describe how you’d like AI to talk with you and where it should be careful.

Step 2

Name it, tag it, and add a tiny AI setting.

Once your first Fragment exists, give it a short title, a few tags, and 2–3 lines about how you want AI to respond on this page.

Fragment が 1 つできたら、短いタイトルとタグを 2〜3 個つけて、「AI にどう関わってほしいか」を数行だけ書いてみてください。 ここでは、形式よりも自分の言葉で書くことを大事にします。

Give it a short name and a few tags

Choose a simple, honest title (for example: “This week — rough notes”) and 2–3 tags you'll actually use later, such as journal, project, or idea.

タグは最初のうちは、3〜8 個くらいの語彙にしぼるのがおすすめです。 「自分があとで検索するときに使いそうな言葉」だけを選んでみてください。

2b

Add one small AI config (YAML)

In Fragment, you can write a small YAML block that tells AI who it should be on this page: what tone to take, and what to avoid.

いきなり難しい設定を書く必要はありません。「こう話しかけてほしい」「これはやめてほしい」を、まずは数行だけ YAML としてメモしてみます。

prism:
  persona:
    name: "Your name"
    role: "gentle thinking partner"
  tone:
    style: "calm, concrete"
  boundaries:
    avoid:
      - "guilt-tripping"
      - "very strong advice without options"

This is the first step toward a reusable Prism profile for this page — written in your own words, not in formal spec language.

Step 3

Try one different way of looking at the same note.

A Fragment can be read in more than one way. After you write your first page, try one alternate view — an outline, a slide-like view, or a simple time-based group.

Fragment の特徴は、「同じノートから、別の見え方をつくれる」ことです。 最初の 1 件が書けたら、アウトラインやスライド風などの見え方をどれか 1 つだけ試してみてください。

Outline view

Turn your headings into a simple outline. Helpful as a talk track, meeting agenda, or a first sketch of slides.

Slide-like view

Show one key point per “slide”. From there, it's easy to copy into PowerPoint or Keynote if you need polished slides later.

Timeline view

Group Fragments by date or theme and see how a week or month evolved. Good for checking “what actually changed” over time.

Habits that help Fragments grow

Fragment を「育てていく」ための、ゆるい習慣の例です。

  • • Leave one small Fragment per day — even just 3–5 lines is enough.
  • • Keep your tag vocabulary small at first (around 3–8 words you actually use).
  • • Once a week, reread 2–3 old Fragments and add a single new line to each.

Tips for a calm, low-noise notebook

Notebook を「うるさくしすぎない」ための考え方です。

  • • Structure can always change later. Early on, focus more on writing than sorting.
  • • Let AI enter after you've written something, so your own voice stays visible.
  • • For important Fragments, add a one-line “why now?” near the top of the page.

Ready to write your first Fragment?

If you've read this far, you already have enough to begin. One real Fragment beats a perfect setup. Choose today's story, your current project, or a note about how you want AI to help — and write just one page in the demo Studio.

ここまで読んだら、準備はもう十分です。完璧なセットアップよりも、まずは 1 件の Fragment。 今日の出来事か、いまのテーマか、AI へのお願いか──どれか 1 つを、 デモ Studio で 1 ページだけ書いてみてください。
