Ai Limit Checker

The AI Limit Checker is a specialized Chrome extension designed to provide real-time visibility into token consumption and rate limits across major AI platforms, including Claude, ChatGPT, Grok, Gemini, and Perplexity. By integrating a sleek, glassmorphism-style floating widget directly into these interfaces, the tool allows users to monitor their context window usage and session limits through dynamic progress bars and "usage pills". It employs a sophisticated hybrid architecture that combines DOM scanning with window.fetch interception to extract precise usage metadata and session reset timers, ensuring users can manage their interactions without hitting unexpected message caps. Built with a focus on privacy, the extension operates entirely locally within the browser, requiring no external data requests or telemetry.
