JM Family Design System
For content strategists

Make every word count. Stop reinventing the same microcopy.

Voice, tone, and terminology guidance that travels with the components users actually see. Approved copy patterns for errors, empty states, confirmations, and onboarding — so every product reads like one product.

Why this helps you

One voice across the portfolio

Same brand, same tone, same terminology — whether the user is on the portal, in an app, or in an email. No more sounding like five companies.

Patterns for the hard moments

Errors, empty states, confirmations, destructive actions — the moments where copy matters most already have tested patterns and examples.

Inclusive language by default

The system documents the language we use and the language we don’t. You start from a foundation that respects the audience you’re writing for.

How to start

Five concrete moves you can make today — each links to the page that gets you unstuck fastest.

  1. Anchor in Voice & Tone

    Read the voice and tone guide first. Every other content decision flows from it.

    Open Voice & Tone
  2. Settle the mechanical questions in Grammar & Mechanics

    Punctuation, lists, abbreviations, acronyms. The lookup page that ends the recurring debates.

    Open Grammar & Mechanics
  3. Pair every UI you write copy for with its component page

    The component page tells you the available states; you bring the words that match the system’s voice.

    Open Components
  4. Read the content-and-voice anti-patterns

    Catalog entries that name failure modes for voice and tone. Read once; spot them everywhere after.

    Open the catalog
  5. Stay sharp on AI writing guardrails

    AI is a teammate, not a shortcut. The guardrails page covers what's safe to ship and what needs human review.
