Features & Capabilities

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.

Is Alt Text Creator Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Alt Text Creator requires a few sensitive permissions. Exercise caution before installing.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Alt Text Creator may not be trust-worthy. Avoid installing if possible unless you really trust this publisher.
