EcoPrompt is a Chrome extension designed to optimize ChatGPT prompts by reducing verbosity. This tool not only saves tokens but also aims to lower CO₂ emissions associated with digital interactions. With its simple toggle feature, users can activate Eco Mode, which rewrites prompts using efficient phrases, ensuring the same message is conveyed more succinctly. The extension provides real-time feedback on tokens saved and the estimated carbon footprint reduction for each optimized prompt, promoting a more sustainable approach to AI usage.

The user interface is minimalistic and non-intrusive, featuring a draggable toggle button that activates the rewriting process. Once activated, EcoPrompt scans the user's input and offers a side-by-side comparison of the original and optimized prompts, allowing for manual adjustments if desired. With a focus on privacy, the extension operates entirely in-browser without data collection or server interactions. It is particularly beneficial for students and professionals looking to enhance their prompt efficiency while contributing to environmental sustainability.
