This manual step ensures errors are caught instead of crashing the workflow. ### **Step 4: Activate Workflow** 1. Click the **"Active"** toggle in the top-right corner 2. The workflow is now listening for Telegram messages ### **Step 5: Test Your Bot** 1. Open Telegram and find your bot 2. Send a TikTok link like: `https://www.tiktok.com/@user/video/123456789` 3.

Forum pulse for Telegram: community monitoring with Gemini & Groq AI models
# ForumPulse for n8n – Daily Pulse & On-demand Deep Dives **Author:** Nguyen Thieu Toan **Category:** Community & Knowledge Automation **Tags:** Telegram, Reddit, n8n Forum, AI Summarization, Gemini, Groq --- ## 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. --- ✨ Crafted by **Nguyen Thieu Toan** with a focus on clarity, reliability, and community-driven insights. This workflow is not just functional - it reflects a design philosophy: automation should feel natural, transparent, and genuinely useful.
