Answer
Reply to accessible notes or attach supported sources. Quizzes support 1–100 multiple-choice questions. The default is ten questions for a general audience at moderate difficulty; without a topic or usable source, AI uses general knowledge.
Quiz context includes up to the past 20 messages without automatically fetching older pins. Reply explicitly to older notes. If a source you require is unavailable, Hashchats explains that limitation instead of inventing facts. There is no manual quiz builder.
Creation and explicit revisions use actual Text tokens at USD 0.010 per 1,000, plus applicable source analysis. The reusable cover has no Image AI charge. Taking, resuming and retaking a quiz add no AI usage.
Scheduled Text requests create fresh quizzes. Include complete instructions and source attachments in the schedule, which has no reply-source picker. The same source-availability rules apply to scheduled runs.
