CrewNews is a Streamlit app designed to generate an unbiased version of the news for a given question or topic by combining content from media providers across the political spectrum in the United States. It uses Llama 3.1 as the LLM (inferenced via the AIML), CrewAI for building AI agents, AgentOps for testing AI agents, Exa as a web search tool, and Firecrawl as a web scraping tool.*

Biases in news reporting can distort public perception, leading to a skewed understanding of important issues and events. When media outlets present information from a single perspective, they risk creating echo chambers where only certain viewpoints are amplified while others are silenced. This not only undermines the integrity of journalism but also affects how individuals form opinions and make decisions based on incomplete information.
In seeking truth you have to get both sides of a story. – Walter Cronkite
CrewNews addresses this critical issue by actively sourcing and presenting content from a diverse range of media providers from the United States, ensuring that multiple perspectives are represented in each report. By utilizing advanced AI technologies, CrewNews fosters a more balanced discourse, empowering users to hear all sides of the story for a given question or topic and come closer to the truth.
For example, here's a part of the report that CrewNews generated for the US Presidential Debate 2024 Harris vs Trump topic:
/.../ The New York Times reported that Harris also slammed Trump for a social media post in which he thanked Chinese President Xi Jinping for his handling of the Covid-19 pandemic [3]. In contrast, Fox News highlighted Trump's assertion that his leadership style was the reason why China and other countries respected him [4]. /.../
If you're a The New York Times reader, Trump === bad. If you're a Fox News reader, Trump === good. Where's the truth? Usually in the middle.

You can verify that the virtual environment is created successfully if you see a folder named my-venv inside the root directory.
Note
venv is a built-in Python module that allows you to create and manage virtual environments. If you have Python 3.3 or higher installed, you can start using venv right away.
Run the following command in the terminal to activate the virtual environment named my-venv:
my-venv/scripts/activateTip
You can verify that the virtual environment is activated successfully if you see (my-venv) at the beginning of your terminal prompt, like this:
(my-venv) C:\your\path\to\crew-news\Run the following command in the terminal to install all the required packages:
pip install -r requirements.txtNote

- Input a question or news topic
The user begins by entering a specific question or news topic they want to explore. CrewNews uses this input to target media sources relevant to the selected subject, creating a foundation for gathering diverse content from media providers across the United States.
- Collecting media providers across the political spectrum
First, CrewNews activates the Media Expert agent to source media outlets representing various political viewpoints—left, center, and right. This ensures the collected content offers a balanced range of perspectives, avoiding bias from any single ideological standpoint.
- Retrieving media provider web domains
After the media providers are gathered, the Web Domain Expert agent identifies and retrieves the web domain URLs of the selected media providers.
- Searching for written news content
Once the web domain URLs are obtained, the Written Content Expert agent utilizes the Exa tool to search for relevant articles from each media provider’s website. CrewNews focuses solely on written content, filtering out videos or images.
- Extracting written content
Following the retrieval of news URLs, the Text Extractor Expert agent uses the Firecrawl tool to scrape the full written content from each news article.
- Creating unbiased news
Last, the Unbiased Journalist agent reviews all gathered content, analyzing how each media outlet reports on the same question or topic. By presenting the viewpoints of left, center, and right media outlets, the agent compiles an unbiased article that offers a complete and balanced perspective. Users can see all sides of the story and form more informed opinions, free from skewed narratives.
CrewNews is built on a modular architecture that employs a crew of specialized AI agents using the CrewAI framework. Each agent is designed to handle specific tasks within the news generation pipeline, allowing for efficient and systematic processing of information.
- Media Expert agent: This agent is responsible for sourcing media providers across the political spectrum (left, center, and right) from the United States. It ensures that the collected content reflects a diverse range of perspectives, mitigating the risks of bias.
- Web Domain Expert agent: This agent retrieves the web domain URLs of each outlet. It ensures that subsequent content extraction processes are performed on valid and accessible websites.
- Written Content Expert agent: This agent utilizes the Exa tool to search for relevant written articles from each media provider’s website. It focuses exclusively on text-based content to maintain analytical consistency.
- Text Extractor Expert agent: This agent employs the Firecrawl tool to scrape the full written content from the identified URLs. It ensures that comprehensive textual data is collected for analysis.
- Unbiased Journalist agent: This agent synthesizes the collected content, analyzing how different media outlets report on the same question or topic. It generates an unbiased article that encompasses all viewpoints.
- Get Media Providers task: Assigned to the Media Expert agent, this task specifies the requirement to collect a balanced number of media outlets from across the political spectrum.
- Get Media Provider Web Domain task: Assigned to the Web Domain Expert agent, this task focuses on identifying and retrieving the web domain URLs of the selected media providers.
- Get Media Provider Written Content URLs task: Assigned to the Written Content Expert agent, this task focuses on searching for and retrieving URLs of relevant written articles.
- Get Written Content From URL task: Assigned to the Text Extractor Expert agent, this task ensures the extraction of full written content from the gathered URLs.
- Get Unbiased News task: Assigned to the Unbiased Journalist agent, this task synthesizes the collected content into a coherent and unbiased article, providing a comprehensive perspective on the chosen question or topic.
- Exa tool: The Exa tool serves as the web search engine, enabling the Written Content Expert agent to perform comprehensive web searches for relevant written content across various media provider websites.
- Firecrawl tool: The Firecrawl tool is utilized for web scraping, allowing the Text Extractor Expert agent to retrieve and parse the HTML content of articles.
- Source URL accuracy: The source URLs included in the final report are usually incorrect. This can lead to
404errors when users attempt to access the article directly from the source URL. - Context window limitations: Due to the Llama 3.1 context window limit, longer inputs can sometimes result in the final report being cut off.
Both of these issues could very likely be resolved with further tweaking of the crew of AI agents.
