Alt Text Creator per Corbin Davenport

Alt Text Creator is a browser extension that generates alternate text for images using the GPT-4o or GPT-4o Mini model from OpenAI. You can right-click on any image and select "Create Alt Text" to generate the text, which is then copied to your clipboard. Alt Text Creator can also use a custom local server with an OpenAI-like API, such as LM Studio.

You must supply your own API key from OpenAI and be on usage tier 1 for the extension to work. Alt Text Creator uses the Low Resolution mode in the API and local caching to reduce the per-image processing cost. The current pricing is available on OpenAI's website.

This browser extension is not affiliated with OpenAI, LM Studio, or the creators of any AI models. The icon uses images from Bootstrap Icons. Check the Privacy Policy for more information about security and privacy. The code is open-source on GitHub.
