Live voice debates, plainly

With Pro or Classroom you talk to the Senate as on a phone call: each senator answers aloud in his own voice, usually within a second, and stops when you interrupt him. These live voices run on OpenAI's realtime speech, which costs us per minute of speech. So that Pro can stay at €4.99 and Classroom at €19 a month, they come with a monthly allowance.

  • Classroom: 20 live voice debates a month. Pro: 3, within its 10 Senate debates a month. A debate counts once, however many speeches it has.
  • After that, nothing stops. The Senate still answers every speech, in the standard voice (slower, generated in your browser). The allowance renews on the 1st of every month.
  • You always see where you are: the Senate shows how many live debates are left this month, and so does your account page.
  • Your voice: only while the live microphone is on, your speech is sent to OpenAI to write it down and let the senators answer. By default OpenAI does not use data sent through its API to train its models.

Calls from history, plainly

Every lesson has a caller: a person standing at the decision the lesson is about, the evening before. On the live lesson board the telephone rings, the class hears who it is, and the teacher answers on the room's microphone. The caller asks what to do, listens, pushes back, and takes the class's advice. Students can also write a line to the caller from their phones. Afterwards the board tells what really happened. With Pro the call comes to you, at home, from the lesson page.

  • Classroom: 20 calls a month. Pro: 5. A call counts when the line connects and lasts up to 5 minutes. The allowance renews on the 1st of every month, and the board and your account page show what is left.
  • Grounded, not improvised: each caller speaks from a short brief of textbook facts about their own moment, knows nothing of what came later, and never tells the outcome. The teacher reads it afterwards.
  • Written with care: no caller is a perpetrator of an atrocity, and no call asks children to advise on violence. Where no dignified call exists, the lesson has none.
  • The room's voice: while the call is open, the microphone's sound goes to OpenAI's realtime speech to let the caller hear and answer. The transcript of the call is kept with the lesson's report for the teacher.
