What's the difference between the AI models?

Florence is fastest and cheapest for simple images. Gemini Flash offers the best balance of speed and quality. GPT-4o and Claude provide premium descriptions for complex images with nuanced understanding.

How does Sirv auto-update work?

If your images are on Sirv CDN, alt text automatically updates in Sirv's metadata. No copying or manual import needed-just enable auto-update and process.

What export formats are available?

Download CSV with filename and alt text columns (works with most CMS platforms), copy all to clipboard, or auto-sync to Sirv CDN.

Does this help with SEO?

Yes! AI generates search-engine optimized descriptions. Well-written alt text is a key SEO factor-search engines use it to understand image content and improve rankings.
