# Gremlins: Data Harvesters

Gremlins are Mavera's sophisticated data collection agents, designed to efficiently gather large volumes of data from specific sources while maintaining a balance in sentiment and perspective.

### Key Features

1. **Source-Specific Scraping**: Each Gremlin is created for a specific website or data source, allowing for optimized data collection.
2. **AI-Powered Navigation**: Gremlins use AI-informed copies of tools like Selenium and Puppeteer to navigate and extract data efficiently.
3. **Balanced Data Collection**: Gremlins are programmed to seek out sources with balanced sentiment, ensuring a diverse and unbiased dataset.
4. **High-Speed Processing**: On high-performance hardware, Gremlins can process approximately 800,000 data sources per hour.
5. **Adaptive Scraping**: Gremlins can adjust their scraping strategies based on the structure and content of each source.

### How Gremlins Work

1. Gremlins receive instructions from Ellie or human users about which sources to scrape, including any subdomains.
2. They navigate to the specified sources using AI-enhanced web scraping tools.
3. Gremlins extract relevant data, continuously assessing the sentiment balance of the collected information.
4. The scraped data is then processed and stored for further analysis by other components of the Mavera ecosystem.

### Benefits

* **Comprehensive Data Collection**: Gremlins ensure that no relevant data is missed, providing a solid foundation for analysis.
* **Efficiency**: The high-speed processing capabilities of Gremlins allow for rapid data collection and analysis.
* **Balanced Perspective**: By seeking out diverse sentiments, Gremlins help prevent bias in the collected data.
