Map Marklet is a bookmarklet for Google Maps that lets you bookmark locations to your Google Maps account.

The app automatically loads the map you want to see and lets you add a location as a bookmark for later access. You can also choose which map to view, making it easy to browse maps from various locations. To add a marker to a specific location, select the "Add Marker" button in the popup and choose what type of marker you want.

When you select a bookmark, the popup shows the location of the bookmark in Google Maps so you can quickly find your location on a map. This makes it easy to navigate and find your way around the world.
