    I doubt that there are similar programs, for a screenshot with image analysis.
    I’m almost sure that these tasks need to be divided into two.
    1) a screenshot, some kind of program that allows you to launch something, after each screenshot.
    2) image analysis by an external program.
    Or a script for ImageMagick, or connect some kind of AI, or other.
    but I’m not familiar with this.

    Can be done in QGIS.

    Add Google Satellite basemap to QGIS
    Add your polygon to QGIS
    Zoom the view to the polygon so the map extent is occupied as much as possible with your polygon
    Save the google satellite using:
    Export the Google Satellite layer
    Save As Geotiff, clear the box against "Create VRT",
    Provide a filename
    Click Map Canvas Extent
    For Resolution, choose horizontal and vertical, make them the same. Play with the value and keep an eye on the columns to make sure they are not too big. Maybe start with 10. Column values in the 1000 to 2000 should be fine. Depends on your use case.
    Click OK

    Now to clip that saved tiff file to your polygon
    On the top menu bar, click raster then extraction then clip raster by mask layer
    input layer = the saved tiff file from above
    mask layer = your polygon
    then click run, to save to a temporary layer or you can save to a file

    You may need to consider Google Earth's conditions of use in regard to using their imagery and how your target audience may react.

    global mapper I had success but have no time to try mapinfo is it's not an application I use much

    load your polygon into global mapper
    zoom to the selected layer (your polygon)
    get world imagery from online source
    select your polygon using the digitizer
    right click on world imagery, then options, then go to the cropping tab
    click on crop to currently selected polygon(s) and click ok
    you can then export the layer

    try export as PNG
    you'll need to play around with the sample spacing to get an image that suits your use case

    Finally, is there any online map that can show only buildings like below example
    (better to be in GlobalMapper)

    or much better to be like below OSM buildings map

    Not that I am aware of, but I haven't looked deeply into it.

    You could try taking images from a site of your choosing and Geo-referencing them in global mapper, then crop the geo-referenced image to your polygon.
