What is the AI Plugin JSON Downloader?
ai-plugin.json is a manifest file that was made for ChatGPT plugins. It sits at /.well-known/ai-plugin.json and describes the plugin name, what it does, how to log in, and where its OpenAPI spec is.
ChatGPT plugins are now retired, but many sites still keep this file, and it is a good example of how AI tools find APIs. Our tool downloads it and shows the key details, including a link to the API spec you can then open with our OpenAPI downloader.
How to use it
- Type or paste the website address, like
example.com. You can also paste the full link to the file. - Press the button. We look for
/.well-known/ai-plugin.jsonin the right place on that website. - Read the simple summary to see what the file says.
- Press Download to save the file, or Copy text to paste it anywhere.
