The course chat

Every indexed course page has one Chat with this course panel. (Until November 2026 there were two, "Ask the course tutor" and "Chat with the sources"; they gave the same answers, so they became one.)

• Ask, then ask a follow-up. The chat remembers the conversation, so "can you give an example of that?" works. New conversation starts over.
• Answers come from the course's own sources. Each answer cites numbered sources; open Sources used and click one to read it: a lesson opens at the passage, a source opens its page or the course's Sources page. Learners are only ever answered from published lessons.
• Grounding is strict by default (if the sources don't cover it, the chat says so) or mixed (sources first, labeled general knowledge when they fall short), set per course on Admin, Course chat.
• Who can use it: only the platform owner, until the owner turns on Course chat for everyone else on Admin, Course chat (off by default). After that, each course's setting there decides: only the owner (the default for a course with nothing saved), its editors and enrolled learners, or its editors and learners enrolled on a paid course. The brand's AI tutor switch in Brand settings turns it off for that school's learners.
• Language courses also show the sentence coach on exercise lessons: a learner writes a sentence and gets a verdict, a correction and the rule, from the same sources.

Nothing a learner asks is saved. The platform owner's own conversations are saved for them alone.
