Stay ahead of the curve with this smart Hacker News monitor. Unlike simple RSS feeds, this workflow uses a custom "Gravity Score" algorithm to identify rising trends and filter out noise, pushing a clean, summarized digest to your Telegram.

✨ Key Features

  • 🧠 Smart Algorithms:

    • Gravity Score: Calculates popularity based on points, comments, and time (velocity), ensuring you see trending stories, not just old ones.

    • Noise Filtering: Automatically discards "infancy" posts (new posts with zero engagement) to keep your feed high-quality.

  • 🤖 Optional AI Translation: Includes an AI Agent (via OpenRouter/LLM) to translate titles and summaries into your local language (e.g., Chinese, Spanish, French).

Don't need translation? Simply delete the Translate node and connect the Filter node directly to the Combine message templates node.

  • 📱 Beautiful Telegram Format: Delivers a clean HTML-formatted digest with clickable links, stats (Points/Comments), and story previews.

⚙️ How It Works

  1. Schedule: Runs every 4 hours (configurable) to fetch data from the past 24 hours via the Algolia API.

  2. Analyze: Calculates the velocity score for each post and filters out low-quality entries.

  3. Translate (Optional): Uses an LLM to translate the content. You can customize the target language in the AI Agent's system prompt.

  4. Format & Send: Combines the data into a structured message and pushes it to your Telegram Chat/Channel.

📝 Setup Instructions

  1. Telegram Credentials:

  • Create a bot via @BotFather.

  • Add the Bot Token to the Telegram node credentials.

  • Get Chat ID.

  1. AI Configuration (Optional):

  • Configure your LLM credentials (e.g., OpenRouter, OpenAI).

  • In the "Translate" (AI Agent) node, edit the System Prompt to change the target language (Default is set to translate to Chinese).
