CiteTutor: a local tutor that verifies before it answers

说明与用途

CiteTutor 是一个本地辅导工具，在显示答案前进行验证，使用多种 LLM 进行草稿和来源验证，并提供页面级引用。

问题

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

结果

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.

工作流

• Upload PDF notes
• Ask a question or request a quiz
• Retrieve relevant chunks via BM25 + cosine similarity
• Gemma drafts answer with chunk IDs
• Blind Qwen verifies source support
• If verified, display answer with citations; else retry or refuse
• Generate practice questions with separate verification
• Human reviews OCR‑transcribed scans before ingestion

证据

Gemma spent 24.84 seconds drafting an answer, and two Qwen checks took another 20.48 seconds.

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.
