Watches a folder for new papers, pulls out title, authors and abstract, and files them against the right week.
Asks you three questions every Monday about what you got done and what you are avoiding, and keeps the answers.
Prepares the week's handout from your notes and has it sitting ready on Thursday morning.
Does nothing until you bring it something, then goes looking for the weakest part of it.
Four jobs, four sizes of model, no conversation between them. The model is chosen to fit the work rather than to impress: filing wants something small and quick, arguing wants the biggest thing your machine will run. Note the bottom line on every card. What it may do while you are asleep, and where it stops.
