Slack Bot for n8n Template Search with AI Tips, Cache and Analytics

Search n8n workflow templates directly from Slack with AI-powered suggestions. Mention the bot with what you need in English, Spanish or Japanese and get matching templates plus actionable tips to improve your automation.

Who is this for

Teams using n8n who want to find workflow templates without leaving Slack. Great for multilingual teams and onboarding new members.

What this workflow does

• Detects user intent (search, help, or browse categories) and routes accordingly
• Extracts keywords from 200+ known services and translates 150+ Japanese business terms to English
• Checks a Google Sheets cache before calling the n8n Templates API
• Uses OpenAI (gpt-4o-mini) to generate contextual tips based on the search results and use case
• When no templates are found, the AI suggests alternative keywords and how to build the workflow from scratch
• Logs every search to Google Sheets and posts a weekly usage report to Slack

Setup

1. Create a Slack App with app_mentions:read and chat:write scopes
2. Set Slack credentials in n8n
3. Create an HTTP Header Auth credential for OpenAI (name: Authorization, value: Bearer sk-your-key)
4. Create a Google Sheet with two tabs: Cache (SearchQuery, CachedResponse, ResultCount, Timestamp) and Analytics (Timestamp, User, Query, Keywords, ResultCount, Intent, FromCache)
5. Connect the Google Sheet in all four Sheets nodes
6. Select your Slack channel in the Trigger, Error Reply and Weekly Summary nodes
7. Activate and test with a mention
