How it works

ForumPulse is an AI-powered assistant that keeps you connected to the latest discussions around n8n.
The workflow integrates Reddit (r/n8n) and the n8n Community Forum, fetches trending and recent posts, and uses Gemini/Groq AI models to generate clean, structured summaries.

It works in two complementary modes:

1. Daily Pulse (Automated Digest):
   Runs on schedule (default: 8:00 AM) to gather highlights and deliver a concise summary directly to your Telegram.

2. On-demand Deep Dive (Interactive):
   Listens to Telegram queries in real-time, detects intent (search, deep dive, open link, or chat), and provides summaries, comments, and insights for any chosen post.

When AI intent detection confidence drops below 0.7, the bot automatically asks for clarification before proceeding—ensuring accuracy and transparency.

Step-by-step

1. Setup & Prerequisites

• n8n instance (cloud or self-hosted).
• Telegram Bot (created via BotFather).
• MongoDB (optional, for persistent memory).
• API keys for Gemini and Groq.
• Your Telegram user ID (to receive replies).

⚠️ Replace all test credentials and tokens with your own. Never commit real secrets into exported templates.

2. Daily Pulse Automation

• Schedule Trigger runs the workflow every morning at the configured time.
• Reddit + Forum Search collects hot/new topics.
• Merge Results combines both sources into a unified dataset.
• AI Summarizer Overview condenses the results into a short, engaging digest.
• Telegram Output delivers the digest, automatically split into safe chunks under 2000 characters.

3. On-demand Interaction

• Telegram Trigger listens for incoming messages.
• Intent Analysis (AI Agent) classifies the query as Search | Open Link | Deep Dive | Chitchat.
• Confidence Gate: if confidence < 0.7, sends a clarification prompt to the user.
• Branch by Intent:
  • Search: Query Reddit/Forum with filters.
  • Open Link: Fetch details of a specific post.
  • Deep Dive: Retrieve comments and metadata.
  • Chitchat: Respond conversationally.
• AI Summarizer structures the output, highlighting trends, issues, and takeaways.
• Telegram Delivery formats and sends the reply, respecting HTML tags and message length.

4. Deep Dive Details

• Post Extraction fetches titles, authors, timestamps, and stats.
• Comment Parsing organizes replies into structured data.
• Merge Post + Comments builds a complete context package.
• Summarizer produces detailed, actionable insights.

5. Error Handling & Safety

• Confidence Check prevents wrong answers by requiring clarification.
• Error Paths handle API downtime or unexpected formats gracefully.
• Auto Chunking avoids Telegram’s message length cap (2000 chars).
• Safe Defaults ensure fallback queries when inputs are missing or unclear.

Customization Options

• Sources: Add or replace platforms by editing HTTP Request nodes.
• Schedule: Change the cron time in the Schedule Trigger (e.g., 7:30 AM).
• Filters: Adjust default sort order, time ranges, and result limits.
• AI Persona: Reword the systemMessage in AI Agent nodes to change tone (professional, casual, emoji-rich).
• Languages: Auto-detects user language, but you can force English or Vietnamese by editing prompt settings.
• Memory: Enable MongoDB nodes for persistent user context across sessions.
• Integrations: Extend beyond Telegram—send digests to Slack, Discord, or email.
• Models: Swap Gemini/Groq with other supported LLMs for experimentation.
