- Quality varies by contributor—some assets get nothing
- Content velocity suffers when teams prioritize alt text
- Existing library sits with missing descriptions indefinitely
With AltText.ai
- All assets processed automatically in the background
- Consistent quality across every image, every language
- Content teams stay focused on content, not descriptions
- Bulk process existing library to close the gap immediately
