In addition to the command line tools in https://github.com/stoerr/chatGPTtools there are some bookmarklets that need to load different stuff from URLs in order to work. So I'm hosting them on https://stoerr.github.io/chatGPTtools/ . That way you'll get the latest version of the code, and I can update it.
To install the bookmarklets in your browser, you can drag the following links into your bookmarks bar. Or you can right-click and copy the link, then add it as a bookmark manually. You can even try this on this page by clicking on it.
If you have problems, please contact me, Hans-Peter Störr.
This lets you select an element in the page and then copies out just that element and its subelements, and all CSS rules that apply to any of those. That way you can copy out the HTML and CSS needed to have ChatGPT answer questions about the CSS. Press 'h' to see the help. See also my blog entry Some experiences using ChatGPT to develop CSS for what this is good for.
This allows you to send the text of any page to ChatGPT for summarization. You can also ask any followup question on the content. It has growing functionality - see the help for details. See also my blog Reading with ChatGPT about this.
You'll need your own ChatGPT API key to run that, which you can get at https://platform.openai.com/. After logging in there with your ChatGPT credentials, you can create an API key in the profile settings (top right corner) at "View API keys". Enter that in the field below. Don't worry - that is just put into the bookmarklet, not transmitted anywhere, except to OpenAI's API when using the bookmarklet.
Bookmarklet to drag: Enter a ChatGPT API Key first. (If you want a quick preview of the dialog, you can click here. That doesn't work, though, since it doesn't have an API key.)
