This tool runs fully offline and can't "see" the image contents — you write the description, and it checks the wording for common accessibility issues. Use the scaffold as a starting prompt, then replace the placeholders with what you actually see.
- 💡 Enter a draft above and click Check alt text to see feedback.
Tips for effective alt text:
- Describe the content and function, not just "image of…".
- Keep it concise — aim for roughly 5–15 words (under ~125 characters).
- Don't start with "picture of" or "image of" — screen readers already announce it's an image.
- Convey context: why is this image here, what does it communicate?
- Use empty
alt=""for purely decorative images.
