What Sage delivers
Pilot status
Where it stands: Phase 0 pilot, Tamil Nadu State Board Class 12 Physics
Early-stage: schema and environment are scaffolded; the pipeline and real chapter content are still to be built. No pilot results are published yet.
- Scope: Physics, Chapters 1-5
- Plan: all seven Class 12 subjects, then Classes 6-11 and other boards
- Results will be published once the pilot has run
Features
Everything the platform does, by area
Ingest
Textbook to structured content.

- Retrieval over chapter content (pgvector)
- Per-chapter question banks
Validate
Machine checks before a human looks.
- Faithfulness to the source text
- LaTeX compile check
- Numeric answer check
Assemble
Balanced papers to a blueprint.
- Constraint solving with OR-Tools CP-SAT
- Marks, topic and difficulty balance

How it works
From first call to live in four steps
Ingest the chapter
Pages are read, structured and reviewed by a teacher before they become source material.
Generate questions
Questions are drafted from the approved chapter content.
Validate automatically
Faithfulness, equation, answer and duplicate checks filter weak questions.
Assemble the paper
A solver builds a paper to the blueprint, ready for teacher sign-off.

The challenge
Good question papers take teachers days, and quality varies
Paper setting is slow
Building a balanced paper from a textbook is repetitive work that pulls teachers from teaching.
Coverage drifts from the syllabus
Hand-built papers over-weight familiar chapters and miss blueprint weightage.
Unchecked AI output is risky
Generated questions can be unfaithful to the text, have wrong answers or broken equations. They need automated checks and a human gate.
How we build
Engineering principles behind every engagement
Teachers stay in charge
Nothing reaches students without teacher review.

- Teacher sign-off on papers
