Inspiration

Every day, we scroll through oceans of information — but not all of it is true. From viral posts to breaking news, misinformation shapes opinions and divides communities. We were inspired to create a tool that empowers people to pause, question, and verify. With the power of AI, we aim to make truth more visible in the digital age.

What it does

Text Reliability Analyzer is a Chrome extension that allows users to instantly evaluate the trustworthiness of any text they highlight online. Powered by Google’s built-in prompt AI APIs, it analyzes language patterns, tone, and factual consistency to generate a clear reliability score and a concise explanation—delivered in real time, directly in the browser. Beyond the overall score, the extension provides a detailed, multidimensional evaluation across five key areas:

  1. Source Authority – Measures the credibility and reputation of the original source.
  2. Evidence Logic – Assesses the logical coherence and strength of supporting evidence.
  3. Content Objectivity – Evaluates the neutrality and potential bias in the text.
  4. Distribution Channel – Considers the reliability of the platform or medium through which the information is shared.
  5. AI-Generated Risk – Detects the likelihood that the content was produced or influenced by AI systems. Together, these insights empower users to read critically, think independently, and build trust in the information they encounter online.

How we built it

We built the Chrome extension using HTML, CSS, and JavaScript, integrating it seamlessly with Google’s built-in prompt AI prompt API for contextual reliability analysis. When users highlight text on a webpage, the content is securely processed by the AI model, which evaluates key credibility signals such as sentiment, bias, and factual consistency. The analyzed results are then displayed instantly within the browser, offering users an intuitive, real-time insight into the reliability of what they’re reading.

Challenges we ran into

Our biggest challenge was optimizing performance while using Google’s built-in prompt AI APIs. During early testing, the initial response time exceeded 60 seconds—far too long for a smooth user experience. We tackled this by refining our JavaScript implementation, improving the communication flow between the extension and the AI service, and optimizing our prompt design for faster, more efficient analysis. These improvements significantly reduced latency and made the interaction feel seamless and responsive.

Accomplishments that we're proud of

We’re proud to have built something that goes beyond technology—a tool with genuine social impact. Our Chrome extension transforms Google’s built-in prompt AI APIs into a real-world solution that empowers users to think critically, recognize misinformation, and foster a healthier online information environment. Seeing our concept evolve into a functional, real-time extension that helps users identify misleading or false content was a moment of true accomplishment. It proves that AI can be more than just a tool—it can be a force for digital integrity and public trust.

What we learned

We learned how to harness Google’s built-in AI APIs to solve real-world problems with social impact. We also deepened our understanding of human-AI interaction — how to make complex AI insights understandable, ethical, and actionable for everyday users.

What's next for Text Reliability Analyzer

Looking ahead, we plan to enhance the extension with advanced capabilities such as cross-source verification, multilingual support, and a user feedback system to continuously improve accuracy. We also aim to refine the AI’s contextual understanding, enabling it to detect emerging misinformation patterns more effectively. Our long-term vision is to create a trusted digital companion that helps users navigate information responsibly—contributing to a more informed, transparent, and resilient online society.
