Turn one devlog into posts for every channel with n8n + AI

A solo game developer automated social media posting by building an n8n workflow that uses Google Gemini to rewrite a single devlog into drafts for Twitter, Reddit, Discord, and a newsletter, saving them to Notion for manual review. The workflow runs locally via Docker and outputs structured JSON drafts, keeping the process authentic and compliant with each platform's rules.

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: 👉 https://shrisab.gumroad.com/l/indie-launch-ops/LAUNCH https://shrisab.gumroad.com/l/indie-launch-ops/LAUNCH Either way, write the devlog once, and stop dreading the four rewrites.
