CarbonCat

Perfect! Here's a Microsoft Edge-friendly description:

Short Description (140 characters max):
Track the carbon footprint of your AI conversations. Your eco companion for mindful AI use. 🐱🌿

Full Description:
Track your AI carbon footprint — one prompt at a time.
CarbonCat helps you see the environmental impact behind every AI interaction. Whether you're using ChatGPT, Claude, Gemini, Perplexity, or other AI tools, CarbonCat calculates your estimated CO₂ emissions and helps you offset them — keeping your creativity and the planet in balance. 🌍🐾
🌿 Key Features
Real-time Carbon Tracking
See the estimated carbon footprint for every AI prompt and response as you chat. A small overlay badge displays emissions instantly, keeping you informed without interrupting your workflow.
Multi-Platform Support
Works seamlessly across all major AI platforms including ChatGPT, Claude, Gemini, Perplexity, and Poe. One extension tracks them all.
Daily & Lifetime Totals
View both your daily carbon usage and cumulative all-time impact. Daily totals reset automatically at midnight, while lifetime tracking shows your overall environmental footprint.
Smart Tokenization
Uses platform-specific token counting algorithms for ~95% accuracy. Different AI models tokenize text differently — CarbonCat adapts to each platform for precise measurements.
Intelligent Artifact Detection
Automatically detects and counts code, documents, and other AI-generated content in your conversations. Never miss the carbon cost of large outputs.
Customizable Daily Limits
Set personal CO₂ goals and receive notifications when you reach them. Stay mindful of your usage with configurable alerts that help you balance productivity with environmental responsibility.
Tree Offset Progress
Visual progress bar shows when you've generated enough CO₂ to offset with tree planting. Each tree absorbs approximately 21kg of CO₂ per year — see exactly when you can make a difference.
Direct Offset Options
When you've earned a tree, donate directly to verified tree-planting partners like One Tree Planted. Turn your digital footprint into real-world environmental action.
Detailed Model Tracking
See which AI models you're using and their relative carbon intensity. Track usage across GPT-4, Claude Sonnet, Gemini Pro, and other models with model-specific emission factors.
Full Customization
Adjust emission factors for different models, toggle response token counting, enable or disable specific platforms, and personalize your tracking experience.
⚙️ How It Works

Install CarbonCat from the Edge Add-ons store
Use your favorite AI tools normally — CarbonCat quietly calculates emissions in the background
Track your daily and all-time carbon footprint through the clean, intuitive popup interface
Set limits to stay within your personal environmental goals
Offset by planting trees when you reach milestones

💚 Why This Matters
AI language models require significant computational energy to generate responses. While each individual interaction seems small, they accumulate quickly:

Average AI prompt: ~50 tokens ≈ 0.15g CO₂e
1,000 prompts monthly: ~150g CO₂e ≈ 1.25 km driven by car
One tree absorbs: ~21kg CO₂ annually

CarbonCat makes this invisible impact visible, helping you understand your digital environmental footprint and make informed, eco-conscious choices without sacrificing creativity or productivity.
