Easy! Give OpenClaw or Hermes (both available in Dappnode) your problem and ask them to query you on what your preferences are, what would you like, etc.
If you use Nexus as the model provider, you keep your personal info private from any profiling company 🕵️
If some of the class info is in PDF, feed it to it, if it's behind password... again, feel free to give it your account details because... the filesystem is yours and only yours and the model provider can't read your password!
