I've switched to a Mac and iPod Touch, so no Sunrise for me anymore.

That said, all that the IE and Firefox extensions actually do is invoke sunrisexp.exe with specific command-line parameters to trigger the "clip" functionality. It should be relatively easy to write a similar extension for Chrome or Safari.

The basic outline of what the script should do is:

1. Obtain the current document's title and URL.
2. Find the path of the sunrisexp.exe executable in the Windows Registry. (Alternatively, use a hard-coded path, so you can skip this step.)
3. Invoke sunrisexp.exe with the -clip option followed by the URL and the title.

Example:

sunrisexp.exe -clip https://www.mobileread.com/ MobileRead

I've attached the Firefox extension's JavaScript code for inspiration. Good luck.

function clipWithSunriseXp() {
	var url = content.document.URL;
	if (url == "about:blank" || url == null) {
		alert("Cannot clip this page. URL not available.");
		return;
	}
	var title = content.document.title;
	var selectionFile = saveSelection();
	
	var sunrisexp = getSunriseXp();
	if (sunrisexp == null) {
		alert("Could not find Sunrise XP executable.");
		return;
	}
	
	var process = Components.classes["@mozilla.org/process/util;1"].createInstance(Components.interfaces.nsIProcess);
	process.init(sunrisexp);
	
	var args = new Array(3);
	args[0] = "-clip";
	args[1] = title;
	args[2] = url;
	if (selectionFile != "") {
		args[3] = selectionFile;
	}
	process.run(false, args, args.length);
}

function getSunriseXp()
{
	var nsIWindowsRegKey = Components.interfaces.nsIWindowsRegKey;
	var registry = Components.classes["@mozilla.org/windows-registry-key;1"].getService(nsIWindowsRegKey);
	registry.open(nsIWindowsRegKey.ROOT_KEY_LOCAL_MACHINE, "SOFTWARE\\DistantChord\\Sunrise XP", nsIWindowsRegKey.ACCESS_READ);
	var installDir = registry.readStringValue("InstallDir");
	
	var sunrisexp = Components.classes["@mozilla.org/file/local;1"].createInstance(Components.interfaces.nsILocalFile);
	sunrisexp.initWithPath(installDir + "\\sunrisexp.exe");
	if (sunrisexp.exists()) {
		return sunrisexp;
	} else {
		return null;
	}
}

function saveSelection()
{
	var selection = content.getSelection();
	if (selection.rangeCount == 0) {
		return "";
	}
	
	var range = selection.getRangeAt(0);	
	var span = content.document.createElement("span");
	span.appendChild(range.cloneContents());	
	var html = span.innerHTML;
	
	var file = Components.classes["@mozilla.org/file/directory_service;1"].getService(Components.interfaces.nsIProperties)
		.get("TmpD", Components.interfaces.nsILocalFile);
	file.append("sunrisexp_selection.html");
	var out = Components.classes["@mozilla.org/network/file-output-stream;1"].createInstance(Components.interfaces.nsIFileOutputStream);
	out.init(file, 0x02 | 0x08 | 0x20, 0664, 0);
	out.write(html, html.length);
	out.close();
	
	return file.path;
