News Aggregator AI Agent - n8n Workflow

Information overload is the silent productivity killer of our digital age. Every day, thousands of news articles, social media posts, and updates flood the internet, making it nearly impossible to stay informed without drowning in irrelevant content. For professionals, researchers, and curious minds alike, manually sifting through multiple news sources, social platforms, and RSS feeds has become an exhausting daily ritual that consumes precious hours while delivering inconsistent results.

Enter the world of intelligent automation with N8N's powerful news aggregation workflow.

By combining multiple data streams with artificial intelligence filtering, this workflow delivers personalized newsletters that cut through the noise and focus on what truly matters to you.

Prerequisites: Setting Up Your News Aggregation Arsenal

Before diving into the workflow construction, you'll need access to several key services and APIs that power this intelligent news aggregation system:

• N8N Platform: Your automation headquarters for orchestrating the entire workflow

Key Components: The Building Blocks of Intelligent News Curation

This N8N workflow leverages a comprehensive suite of nodes that work together seamlessly:

• HTTP Request Nodes: Interface with external APIs for data collection
• AI Language Model Nodes: OpenAI GPT-4.1 and Google Gemini for content analysis
• Split in Batches Nodes: Handle large datasets efficiently without overwhelming APIs

Step-by-Step Implementation: Building Your News Aggregation Engine

Step 1: Multi-Source Data Collection

The workflow begins with parallel data collection from four distinct sources. TikTok scraping targets specific crypto-focused profiles like "cryptomasun" and "virtualbacon" to capture the latest video content. Simultaneously, Reddit scraping searches for trending crypto discussions using advanced parameters that filter by recency and relevance. The Tavily Search API performs sophisticated news queries with topic-specific depth, while the CoinDesk RSS feed provides authoritative industry updates. This parallel approach ensures comprehensive coverage while maximizing efficiency.

Step 2: Content Processing and Standardization

Raw data from different sources arrives in various formats, requiring intelligent processing for uniformity. TikTok videos undergo automatic transcription using Google Gemini's audio processing capabilities, converting spoken content into searchable text. Reddit posts are cleaned and formatted to extract meaningful discussions. All content streams are then standardized into consistent data structures containing essential fields: content text, source URLs, and metadata. This standardization is crucial for the subsequent AI analysis phases.

Step 3: AI-Powered Content Filtering

The heart of the workflow lies in its intelligent filtering system powered by OpenAI's GPT-4.1 model. Each piece of content undergoes rigorous analysis to determine relevance, quality, and authenticity. The AI evaluates factors such as information accuracy, source credibility, and topical alignment. Articles are scored and classified, with only high-quality, verified content advancing to the next stage. This eliminates clickbait, misinformation, and irrelevant posts that would otherwise clutter your newsletter.

Step 4: Visual Enhancement and Optimization

Approved articles receive visual enhancement through automated image selection. The system generates relevant keywords for each piece of content, then uses these keywords to search the Pexels API for professional-quality thumbnail images. This process ensures that every article in your newsletter has appropriate visual representation, significantly improving reader engagement and the overall professional appearance of your publication.

Step 5: Newsletter Generation and Distribution

The final stage transforms curated content into a polished HTML newsletter. Google Gemini's advanced language model creates responsive email templates with modern styling, proper formatting, and mobile-friendly design. The system automatically generates compelling headlines, organizes content logically, and includes all necessary metadata. Once the newsletter is complete, it's delivered via Gmail API to your subscriber list, maintaining professional presentation and deliverability standards.

Customization: Beyond Crypto News

While this workflow focuses on cryptocurrency news as an example, its modular design allows for easy customization to any topic or industry. Simply modify the search parameters, source selections, and filtering criteria to create specialized newsletters for technology, healthcare, finance, or any other field of interest.
