Cathedra

Your lectures in Claude and ChatGPT

Connect the AI you already use to your Cathedra library. It reads your courses, your lectures and their transcripts, your course documents and your timetable, can point at the lecture and the moment an answer came from, and, when you ask, puts an exam or a deadline in your calendar and sets up your timetable.

What it can read

  • Your courses, your timetable and your calendar
  • Your lectures and their transcripts
  • The documents in your courses

What it can change, when you ask

  • The exams, deadlines and events in your calendar: adding them, moving them, removing them
  • Your timetable: adding a course, adding, moving or removing its weekly classes, and calling one class off or adding a make-up class
  • Your recorded lectures: their titles, their dates and the course each is filed under

It cannot change or delete anything else.

Free and paid

On Cathedra Free, a connected AI reads your lectures and documents from the last 7 days. A subscription opens the whole library. See the plans

Your data

You sign in on Cathedra's own page, with the code we email you; Cathedra never sees your Claude or ChatGPT password. What a connected AI reads goes to that AI's company, under its own terms.

You can disconnect it at any time on your account page, and its access stops at once.
