Description

🧠 How it works

This workflow enables automatic translation in Slack using n8n and OpenAI.
When a user types /trans followed by text, n8n detects the language and replies with the translated version via Slack.

⚙️ Features

• Detects the input language automatically
• Translates between Japanese ↔ English using GPT-4o-mini (temperature 0.2 for stability)
• Sends a quick “Translating…” acknowledgement to avoid Slack’s 3s timeout
• Posts the translated text back to Slack (public or private selectable)
• Supports overrides like en: こんにちは or ja: hello

💡 Perfect for

• Global teams communicating in Japanese and English
• Developers learning how to connect Slack + OpenAI + n8n
