About this tool
Good alt text makes images accessible and helps search engines understand them; a good caption makes a post worth reading. Upload an image and a vision-capable AI model writes a short caption, accessible alt text and a social-ready line. The image is resized in your browser before being sent to the AI provider.

Frequently asked questions
Which AI model is used?
The tool uses a vision-capable AI model from an OpenAI-compatible provider. If the AI service is temporarily unavailable, the tool tells you so instead of guessing.
