About

AI Block: Secure Your Browser from the Misuse of Chromes Built-in AI 🛑 

Overview
With the introduction of built-in AI capabilities in browsers, such as Chrome's Gemini Nano, web applications can now perform AI-powered tasks locally, without the need for server-side processing. While this innovation offers remarkable benefits like enhanced privacy, reduced latency, and offline functionality, it also introduces potential risks. AI Block is designed to mitigate these risks by providing users the power to control and block the use of the window.ai API in their browsers completely.

🙋 Why AI Block? 
The window.ai API, a powerful interface for on-device AI, has transformative potential. However, if misused, it could lead to several risks:

🕵️ Privacy Concerns: 
Despite local processing, malicious scripts could leverage AI capabilities to analyze sensitive data without user consent.

🙅‍♀️ Unauthorised Resource Use: 
AI models, particularly sophisticated ones like Gemini Nano, are resource-intensive. Malicious websites might exploit these AI capabilities, leading to significant performance degradation or battery drain.

📊 Data Integrity Attacks: 
On-device AI could be used to alter or fabricate content, potentially misleading users or manipulating information without their knowledge.

👮 Security Vulnerabilities: 
As with any new technology, the integration of AI into browsers can introduce new attack vectors for malicious entities.


Features
