Health checks confirm storage and API readiness—not AI answer quality.
Your knowledge library
Actual indexed books in this LMS workspace.
Proof that it works
Project-wide saved tests. Not a live certification of this LMS.
One token. Many courses. Private student chats.
Your LMS authorizes its students. Central AI handles books, answers and memory.

DOCUMENT EXTRACTION ONLY
Extraction playground
Test PDF-to-text and handwriting-to-text without indexing books.
Private test uploads are scoped to this LMS and test course. No embeddings, exams or grades are created. Hosted OCR can incur charges. This is owner testing, not proof of teacher login or enrollment.
Upload a test document
Uses the saved extraction connection.
Choose Visual OCR for handwriting PDFs, even when printed questions have selectable text. Automatic extraction does not capture all image-only writing or diagram labels. Originals remain available for review.
Your extraction tests
Load test history or upload a document.
Extracted text
Review draft—not certified OCR accuracy.
REAL API · REAL ANSWERS
Chat playground
Ask, follow up, return to history—and see the book evidence.
Isolated by LMS + course + student.

TRANSPARENCY, BUILT IN
Verification center
Separate what is healthy now from what has actually passed a test.
Live checks use real, read-only API calls and negative authorization tests. They do not create accounts, start services or spend model quota. Use the chat playground to test real inference.

Recorded evidence

SIMPLE BY DESIGN
Connect your LMS
Your LMS stays in charge of its users. Central AI stays in charge of knowledge.
The request flow
No LMS database copy or direct browser access to AI secrets.

AI providers
Choose a provider and model for each job. Connect a provider with its API key once.
Connect tests your selection before activating it. Test alone does not save. Keys are encrypted server-side and never returned to the browser. Tiny real tests may incur provider charges. No silent fallback.
Chat and extraction models can change without re-embedding. A different embedding model needs explicit approval to rebuild all books using saved text. Original files and the previous vector index are kept. Extraction changes apply to new uploads; use a book’s Re-extract action to extract it again.
Object storage
Private originals and extracted text. No direct browser credentials.
Storage access stays behind the authenticated API. Existing local books are not migrated automatically. Teacher answer keys and homework workflows are not implemented yet.
Workspace access
Backend-only authentication.
Rotation immediately invalidates the previous token. The browser must never hold an LMS backend token.
Delete LMS workspace
Permanently remove this LMS's Central AI data and revoke its backend token. This does not delete the external LMS application or database.
Includes libraries, files, vectors, conversations, memories and standalone extraction uploads. Other workspaces and shared provider settings remain.
Integration contract
The LMS backend must verify login and course access on every request.
