🔬 Chat with news articles using AI analysis in Telegram with vector search

⚡ 161 views · 🔬 Document Extraction & Analysis

💡 Pro Tip — HTTP Request scraping tends to break when sites update their markup. If you’re scraping a major platform, check if ScraperNode covers it — it has maintained scrapers for LinkedIn, Instagram, TikTok, YouTube, and 20+ other platforms that return structured data.

Description

📌 Overview

This workflow allows users to send any newspaper or article link to a Telegram bot. The workflow then:

1. Validates the URL
2. Scrapes the webpage (title, description, full text, images, OG metadata)
3. Processes it using a Vision-Language Model (VLM)
4. Generates structured summaries & highlights
5. Downloads images (if available)
6. Sends a formatted report + document back to Telegram
7. Stores the summary in a vector database
8. Allows users to chat with the article using semantic search

Perfect for: ✔ News researchers ✔ Students ✔ Journalists ✔ Telegram-based AI assistants ✔ Automated media monitoring

🧠 What the Workflow Does

1. Telegram Trigger

• Listens for messages from the user.
• Detects if the message contains a valid link.

2. URL Scraper

A custom n8n Code node fetches the webpage and extracts:

• Meta description paragraph text
• All image sources
• Open Graph metadata (og:title, og:image)

Returns everything as structured JSON.

3. VLM Run – Highlighter

A Vision-Language Model analyzes the scraped content and outputs:

{
  "news_summary": {
    "headline": "",
    "source_url": "",
    "published_date": "",
    "key_points": "",
    "summary": "",
    "extracted_images_url": ""
  }
}

4. Image Validation & Download

• Checks if image URLs are valid.
• Downloads them (if any).
• Sends them to Telegram as documents.

5. Summary File Generation

• Converts VLM output into a .txt report.
• Sends the report back to the user.

6. Vector Store + Q&A Agent

• Converts the summary into embeddings.

• Stores the vector in an in-memory store.

• Provides the user with a chat interface:

  • Ask anything about the newspaper article.
  • The AI agent retrieves information using the vector store.

📤 Outputs

You receive:

✔ Telegram message summary ✔ Downloadable summary .txt file ✔ Extracted images (if available) ✔ Chat-based Q&A agent to explore the newspaper details
