WattDidISpend
A browser extension and dashboard that estimates the kilowatt-hours and CO2 emitted by your ChatGPT, Claude, and Copilot usage, with comparisons like "this week equals X days of grid power for a household in Lagos."
Environmentally curious professionals, students, and writers who use AI tools daily and want to know their personal footprint
- Browser extension that logs AI tool usage and estimates energy per query using public per-token figures
- Personalized footprint dashboard with country-comparable equivalents (Lagos, rural India, EU average)
- Weekly digest email with concrete reduction tips (use smaller models, batch prompts, switch off when idle)
- Optional low-impact mode that nudges you toward leaner AI workflows during heavy sessions
Concrete AI energy numbers (1.5 kWh per heavy coding day, 200 GW global agent projection) are now circulating publicly, and everyday AI users want to translate those headlines into their own footprint.
Source trend is weak (4 reactions on Dev.to); multiple competing extensions exist, suggesting real but niche interest.ChatGPT Energy Tracker - Chrome Web Store ↗AI Wattch - Track Your AI Footprint - GitHub ↗
Market is crowded with near-identical products: ChatGPT Energy Tracker, ChatGPT Carbon Tracker (Chrome Store), open-source AI Wattch (ChatGPT/Claude/Gemini), and OffsetAI (multi-platform + offsets) — WattDidISpend is not differentiated.ChatGPT Energy Tracker - Chrome Web Store ↗ChatGPT Carbon Tracker - Chrome Web Store ↗AI Wattch - Track Your AI Footprint - GitHub ↗Offset your AI footprint ↗GitHub - palakg28/chatgpt-energy-tracker ↗
OffsetAI markets itself as free; AI Wattch is open-source; personal carbon-footprint extensions historically monetize poorly (offset commissions at best).Offset your AI footprint ↗AI Wattch - Track Your AI Footprint - GitHub ↗
AI energy/regulation is a durable theme (EU reporting requirements, datacenter scrutiny), but novelty may fade once dashboards become routine — moderate longevity.AI Wattch - Track Your AI Footprint - GitHub ↗
Multiple competitors already built token-counting browser extensions for ChatGPT/Claude, proving the technical approach is straightforward.GitHub - palakg28/chatgpt-energy-tracker ↗AI Wattch - Track Your AI Footprint - GitHub ↗
