About

FEATURES
• Detects images pasted into Outlook compose
• AI-generated alt text using Claude vision models
• Smart model selection: Haiku for simple images, Sonnet for complex ones
• Edit suggestions before applying
• Skip option if you don't want alt text
• Privacy-focused: no tracking or data retention

HOW IT WORKS
1. Paste an image into an Outlook email
2. Extension analyzes the image with Claude AI
3. Review and edit the suggested alt text
4. Click "Apply" to add it to your image

SETUP REQUIRED
• Get a Claude API key from console.anthropic.com (free tier available)
• Click the extension icon and enter your API key

COST OPTIMIZATION
Uses conditional model selection to minimize API costs:

- Complex images use Claude Sonnet for accuracy (~$0.01-0.05 per image)

PRIVACY & SECURITY
• Your API key is stored locally in Chrome's secure storage
• Images are sent only to Claude API for analysis

• No tracking or analytics
