A plain guide for game designers to write clear design documents, with the steps, the tools to try and the mistakes to avoid.

Write the one-line pitch and the questions the document must answer, sketch the outline, then expand the shortest version into the sections the team actually reads. Dictate drafts aloud into your editor with QuickDictate if typing slows you down, and keep dated versions so the plan stays traceable.

| Option | How it helps you write |
|---|---|
| Paper and pen | You draft the outline and core loop by hand, then type it up. Price depends on what you already own. |
| A word processor | Headings and a table of contents give the team a structure to read and comment on. Limits and cost are not published here. |
| QuickDictate | Types what you say into whichever window you are using, such as an editor, chat box, terminal or web form [^1] [^1]. Free for personal and other noncommercial use, with no subscription or account [^1]; cloud providers bill you separately [^1]. |

## What you need before you start

Writing a design document takes only a few things.

- **A clear idea of the game.** Know what the game is in one line before you start. If it cannot be put in one line, the document will struggle later.
- **A list of the questions it must answer.** A design document works when it answers what a team asks: what the player does, why it is fun, and how it is built. List those questions first.
- **A form the team will read.** Some teams read long text, others want a page of bullet points. Pick the shape before writing.
- **A place to keep versions.** Design documents change often, so a place that keeps old versions helps the team see how the design grew.
- **The tools you already have.** A pen, a word processor or a dictation tool all work. Use what is already in front of you.
- **A time block.** Writing a whole document at once is hard. Set aside a short block and write one section.

Set a short block before you begin. Writing while the team is already mid-build tends to produce notes nobody reads.

## Step by step

These steps work with any tool, including a pen and a sheet of paper.

1. **Write the one-line pitch.** Describe the game in one sentence, such as the core loop and what makes it fun.
2. **List the questions the document must answer.** Write them as headings so each section earns its place.
3. **Sketch the outline before the words.** A list of section names is faster to fix than a finished page.
4. **Write the shortest version first.** Start with the core loop: what the player does minute to minute and why it holds together.
5. **Answer the hard questions in each section.** For each heading, state the decision and one reason for it, so the team can argue with facts rather than feelings.
6. **Keep numbers to what is true now.** Only include values you are ready to defend, because the team reads them as promises.
7. **Write so a new teammate understands.** Explain the words only your old team knows, or the document does not travel.
8. **Read it once as the reader.** Go through the draft top to bottom and look for sections that assume knowledge nobody has yet.
9. **Save a new version with a date.** Keep the old one so changes stay visible.
10. **Share it and leave a place for questions.** A document with no place for feedback is a wall, not a plan.

## Tools that can do it

You do not need special software to write a design document. Here are options to consider.

**Paper and pen.** You draft the outline and the core loop by hand, then type it up. Nothing is published here about price because it depends on what you already own.

**A word processor.** A document with headings and a table of contents gives the team a structure to read and comment on. Facts about specific word processor apps are not provided here, so check their own pages for limits and cost.

**QuickDictate.** QuickDictate is made by the team that publishes this site. QuickDictate is one option. It is a Windows program that types what you say into whichever window you are using. [^1] You hold a key while you talk, or press it once to start and once to stop, and you can change both keys. [^1] What you say is typed into whichever window has focus, such as an editor, chat box, terminal or web form. [^1] You can use ElevenLabs, Deepgram, OpenAI, AssemblyAI, DashScope or Google, and that provider bills you directly. [^1] Choose Local in Settings and install a speech model such as Whisper Large v3 Turbo; dictation then needs no internet connection or API key. [^1] With some cloud providers, words appear while you are still talking. [^1] You can list words and phrases that are sent to the provider to help it recognise them, and a replacement table fixes spellings such as "Chat GPT" to "ChatGPT". [^1] Profiles can change the provider, language, vocabulary and formatting depending on which app is in focus. [^1] You can browse and filter your last 50 dictations in Settings, and the history survives a restart or self-update. [^1] Saying "scratch that" discards the text you just dictated instead of inserting it. [^1] While you are dictating, other apps' audio is muted or turned down, and it goes back to its old level when you stop. [^1] If you sign in, you can sync preferences such as hotkeys and language between PCs; API keys, audio and transcripts are never synced. [^1] QuickDictate is free for personal and other noncommercial use, with no subscription or account. [^1] Cloud providers bill you separately for their service. [^1] From v0.9.0 on, it is source-available under PolyForm Noncommercial 1.0.0: free for personal and other noncommercial use, and commercial use needs a separate licence. [^1] It runs only on 64-bit Windows 10 and 11, and there is no Mac or Linux version. [^1] It is delivered as an .exe file on GitHub, with a built-in updater that works silently. [^1]

## Common mistakes to avoid

**Trying to describe the whole game at once.** Describing every mechanic at the start makes the document long before it is clear, and the parts that matter get buried. Do the one-line pitch and the core loop first, and expand only what the team asks about.

**Writing a history of meetings.** A design document records decisions, not meetings. If a section only restates what was discussed, cut it.

**Putting in numbers nothing defends.** Values the team reads as promises, so only include ones you can stand behind.

**Writing for the old team.** Use words a new teammate understands, or the document does not travel.

**Making it one long wall of text.** Section titles and bullet points give a reader an entry point.

**Never touching it again.** A design document is a living plan. If it stops changing, the team stops reading it.

## Frequently asked questions

### Do game design documents have to be long?

No. A one-page version that answers the team's questions beats a long file nobody reads. Start with the one-line pitch and the core loop, then expand only the sections the team actually asks about. Let length follow what the project needs rather than a fixed page count, and keep a dated version so changes stay visible.

### Can QuickDictate type into any window during design work?

Yes. QuickDictate types what you say into whichever window has focus, such as an editor, chat box, terminal or web form, so a draft can go straight into a word processor. [^1] You hold a key while you talk, or press it once to start and once to stop, and you can change both keys. [^1]

### Does QuickDictate need a subscription for game designers?

No. It is free for personal and other noncommercial use, with no subscription or account. [^1] Cloud providers bill you separately for their service. [^1] Commercial use needs a separate licence, so check which use yours counts as before you start. [^1]

### Can a design document be dictated with custom game terms?

Yes. You can list words and phrases that are sent to the provider to help it recognise them, and a replacement table fixes spellings such as "Chat GPT" to "ChatGPT". [^1] Profiles can change the provider, language, vocabulary and formatting depending on which app is in focus. [^1]

### Which Windows versions does QuickDictate run on?

It runs only on 64-bit Windows 10 and 11, and there is no Mac or Linux version. [^1] It is delivered as an .exe file on GitHub, with a built-in updater that works silently. [^1]
