Green Prompting – Sustainable AI Awareness

Green Prompting is a tiny governance layer on top of your AI usage. It shows a minimal, non-blocking overlay on popular AI tools (ChatGPT, Gemini, Claude, Perplexity, Copilot, etc.) with rough guesstimates of: – Current prompt size (tokens) – Electricity use (kWh) – Water use (liters) – Lifetime totals of tokens, energy, water, and prompt count (per browser) You also get a rotating strip of Sustainable AI offers that you control entirely from a simple Google Sheet (Offer, Link, CTA). Use it to highlight your own tools, research, or partner solutions. How it works – Uses a simple heuristic to estimate tokens from characters, then converts to kWh and liters with transparent constants in content-script.js. – No integration with any AI provider or API. It just watches what you type into AI prompt boxes in your browser. – Lifetime stats are stored locally using chrome.storage.local. – Offers are loaded read-only from a public Google Sheet you configure. Privacy – No prompt text is stored. – No user IDs, emails, or URLs are stored. – Only anonymous numeric aggregates (tokens, kWh, liters, prompt count) are kept locally in your browser. – Nothing is sent to any external server by this extension. Disclaimer All numbers are guesstimates only. They are not suitable for formal reporting, compliance, or precise climate accounting. The goal is awareness and better conversations about sustainable AI usage.
