CiteTutor: a local tutor that verifies before it answers

Описание и применение

CiteTutor – локальный помощник, который проверяет ответы перед их показом, используя несколько моделей LLM для черновика и верификации, и предоставляет ссылки на страницы источника.

Задача

Students need reliable, source‑anchored explanations from local course materials without exposing content to external services.

Результат

CiteTutor achieved 7/7 supported answers with correct citations after revisions, eliminated false refusals, and maintained a median latency of 44.5 s on an 8 GB Apple M1.

On an 8 GB Apple M1, I ran ten questions against an original three‑page mechanics PDF. The preserved reports show: Supported answers correct 7/7, False refusals on supported questions 0/7, Unrelated questions refused 3/3. Returned tutor latency was 44.5 seconds median.
