Three steps to a course-aware TA
Upload your course materials
Readings, lecture notes, chapters, cases — the same content you assign to students. The Virtual TA is grounded in whatever you upload; nothing beyond it.
Share the access code
Every Virtual TA has a shareable name plus a short access code. Give both to your students — via syllabus, LMS announcement, or a link — and they're in.
Students ask, TA answers
Students type questions in any language. Answers come back from your corpus with references to the specific chapters or readings, plus one-click follow-ups.
An answer from your material. With references. And follow-ups.
Below is a sample exchange — not from a real student. Actual answers come from whatever course materials you upload, in whichever language the student asks.
Bramwell — Strategic Management
In chapter four, how does Bramwell distinguish between a firm's resources and its capabilities under the Resource-Based View?
Bramwell separates them by treating resources as the tangible and intangible assets a firm owns or controls — physical plant, patents, brand equity, technical know-how — while capabilities are the organizational routines that let the firm deploy those resources productively. The distinction matters because a firm with strong resources but weak capabilities cannot convert asset stocks into competitive outcomes; conversely, a firm with distinctive capabilities can outperform even when its resource base looks unremarkable on paper.
Students can ask in their native language. Answers reference the same chapters and pages you assigned.
FERPA-compliant. Grounded, not guessing.
Answers come only from the course materials you upload. The Virtual TA does not draw from the open internet or from what a frontier model happens to know about your subject.
Student questions and conversations are never used to train AI models — yours, ours, or any third-party provider's.
You control the corpus. Add, update, or remove materials at any time and the TA reflects the change on the next question.
Data is encrypted in transit and at rest. Per-course usage stays scoped to that course, not shared across accounts.
