SustAIn

SustAIn helps you shorten prompts before sending them to AI models. It adds a lightweight compression tool directly inside supported AI chat websites so you can fit more instructions within model limits, reduce token usage, and keep your workflow fast. SustAIn compresses long prompts before you send them, helps you stay within context and usage limits, and lets you undo prompt changes quickly. It also tracks usage and savings such as tokens, compression percentage, water, and energy, making the environmental impact of AI usage more visible. By reducing unnecessary tokens, SustAIn helps lower the compute, water, and energy associated with large AI models while preserving the core meaning and key instructions of your prompt. SustAIn helps compress prompts on supported AI chat sites, including major tools like ChatGPT and Gemini.
