What is alt text?

Can I copy the result as an HTML attribute?
Yes. Select the alt attribute option next to the result, then copy the escaped alt="…" text.
How long should alt text be?
Aim for about 125 characters or fewer, but prioritize the image's purpose over a strict character count. Avoid starting with “image of.”
Do I need to check AI-generated alt text?
