If you're a solo game developer, you know the drill: you ship an update, write a devlog… and then you have to rewrite it four times. A punchy tweet. A longer Reddit post that doesn't sound like an ad. A casual Discord ping. A newsletter blurb. By the third rewrite you've lost the will to post at all.

I automated the rewriting with **n8n**, **Google Gemini**, and **Notion**. I write the devlog once, hit run, and get channel-ready drafts waiting in Notion. It **doesn't auto-post**, it makes drafts I review and send myself, which keeps everything authentic and inside each platform's rules.

Here's a short demo of the finished workflow:

👉 [https://www.loom.com/share/f108f0a003b448b2bc414a8be742d772](https://www.loom.com/share/f108f0a003b448b2bc414a8be742d772)

For one devlog you paste in, it:

The flow looks like this:

```
Manual Trigger
  → Devlog Input
  → AI Reformat (Gemini)
  → Parse Drafts
  → Save Drafts to Notion
docker volume create n8n_data

docker run -d --name n8n \
  -p 5678:5678 \
  -v n8n_data:/home/node/.n8n \
  docker.n8n.io/n8nio/n8n
```

Open [http://localhost:5678](http://localhost:5678) and create your account.

Add a **Code** node where you write your update once. Keeping it in a Code node means you just edit two variables each time:

``` js
const devlog_title = "Update 0.3 — Online Co-op";
const devlog_body = `We just shipped online co-op for up to 4 players,
fixed the save-corruption bug, and added 2 new levels.
Next up: controller support and a Steam demo.`;

return [{ json: { devlog_title, devlog_body } }];
```

(Later you can swap this for a **Form Trigger** so you get a little web form, or a **Notion Trigger** that fires when you add a devlog page.)

Add the **Google Gemini** node. The trick is to make it return **strict JSON** so the next node can split it cleanly:

```
You are a social media manager for a solo indie game developer.

Here is a devlog update:
Title: {{ $json.devlog_title }}
Body: {{ $json.devlog_body }}

Rewrite it for each channel. Return ONLY valid JSON (no markdown,
no code fences, no text outside the JSON) with these exact keys:
{
  "twitter": "280 characters max, punchy, 1-2 relevant hashtags",
  "reddit": "friendly longer post for r/IndieDev, first person, no hashtags, no hard selling",
  "discord": "casual short announcement for a community server, 1-2 emojis ok",
  "newsletter": "2-3 sentence email blurb"
}
```

LLMs sometimes wrap JSON in code fences, so a small **Code** node cleans and parses it, with a fallback so you never lose output:

``` js
const raw = ($json.content?.parts?.[0]?.text) || "";

// \x60 is a backtick (char code 96). This strips a code fence
// if the model wraps its JSON output in one.
let clean = raw.trim()
  .replace(/^\x60{3}json\s*/i, "")
  .replace(/^\x60{3}\s*/, "")
  .replace(/\x60{3}$/, "")
  .trim();

let parsed;
try {
  parsed = JSON.parse(clean);
} catch (e) {
  parsed = { twitter: "", reddit: raw, discord: "", newsletter: "" };
}

const input = $('Devlog Input').item.json;

return [{
  json: {
    devlog_title: input.devlog_title,
    twitter: parsed.twitter || "",
    reddit: parsed.reddit || "",
    discord: parsed.discord || "",
    newsletter: parsed.newsletter || "",
  }
}];
```

Create a Notion database called **Devlog Drafts** with these properties: **Name** (title), **Twitter** (text), **Reddit** (text), **Discord** (text), **Newsletter** (text), **Status** (text), **Created** (date).

Create an internal integration at notion.so/my-integrations, connect it to the database, then map the fields in n8n's **Notion** node. Set the title to `{{ $json.devlog_title }}`

and each channel field to its matching value (`{{ $json.twitter }}`

, etc.).

Run the workflow and you'll get a new row with four drafts - review, tweak, and post whenever you like.

I packaged this, plus a Steam competitor-tracking workflow - into an importable pack with setup guides, the AI prompts, troubleshooting, and example screenshots:

Either way, write the devlog once, and stop dreading the four rewrites. Questions welcome in the comments.
