mariosemes/PornHub-downloader-python — reverse-engineered prompt

Build me a simple Python command line tool that makes it easy to download videos from PornHub. On first run it should ask where I want downloads saved, remember that in a local database, and then let me manage the sources I want to follow. I want to be able to download a single video URL, or add a model, pornstar, channel, user, or playlist so the app can keep track of them over time. It should also support batch import from a text file with one URL per line.

Please add clear commands to start downloads, list what is saved, and delete entries by ID. When I add a source, pull the nice display name from the site so the final folders look clean and organized. The start command should first handle anything newly added, then check older saved sources for new videos and download those too. Keep it straightforward and easy to run with Python 3. If the old approach is outdated, look up current docs online and make it work with the same general behavior.
