Grounded · Verified · Offline · Human-led
Every claim cites the manual — or the system refuses. Answers are verified on-device against the source, the delivery loop runs with the network pulled, and a human ratifies everything before it reaches a learner.
Most AI tutors will confidently invent an answer. In a schoolhouse — where the "answer" is doctrine people are tested and evaluated on — that is unacceptable. Groundwork is built so it can't:
- Grounded — every answer quotes the exact paragraph of the source, or it says "I don't know."
- Verified — an on-device entailment check confirms the specifics are actually supported.
- Offline — the delivery loop runs on a small edge device with no internet. $0 per answer.
- Human-led — AI drafts; an instructor approves, edits, or rejects. Nothing unreviewed ships.
SchoolCircle is the learning management app instructors and students use, and it is running at schoolcircle.tannerwhite.net. Anchor is the grounding engine that every answer flows through. The rest of the repos are single-purpose services the app composes into two closed loops:
- Instructor loop — build a grounded course, review AI-drafted items, see class-wide gaps, improve.
- Learner loop — learn, ask a cited tutor, get calibrated by confidence-vs-correctness, master it.

Grounded, verified, offline, human-led. If a claim isn't in the source, the system refuses rather than guesses. That guarantee is the product.
