Source-safe NCERT locator library

Study NCERT Chemistry through PrepAI retrieval.

This is not a PDF dump. PrepAI maps approved NCERT source coordinates to outcomes, formulas, PYQ provenance, and reviewed practice actions for the Class XII Chemistry Part 1 pilot.

Current pilot coverage

5 chapters, locator-first

The portal gives every chapter a study path, source locator, formula entry point, PYQ provenance lane, and reviewed-practice link without exposing copied source text.

Trust constraints

PrepAI shows how the study loop is constrained before asking for trust.

No unverifiable launch claims

Source-safe

Official sources guide structure and coordinates; PrepAI content stays coordinate-based.

Deterministic tools

Chemistry calculators and paper compilation use local rules, not runtime AI guesses.

Answer-masked

Answers, explanations, and rubrics stay locked until the student commits a response.

Review-gated

Questions must pass content review before DPP, practice, assignment, or mock use.

Secure rendering

Formula rendering uses KaTeX with trust:false and unsafe math commands blocked.

Source-to-study pipeline

Knowledgebook operating board

PrepAI turns official source coordinates into a reviewed study workflow. The portal shows what is indexed, what is review-gated, and what is student-actionable without becoming a textbook mirror.

No ZIP or textbook redistribution surface: this page routes students to locators, original explanations, formulas, reviewed practice, and paper generation. The public coverage board shows current reviewed-bank density before strict paper generation.

1. Source locator

Indexed

Official NCERT portal, class, subject, book, chapter, and section coordinates.

2. Outcome map

Live for pilot

Chapter topics connect to PrepAI outcomes, formulas, PYQ provenance, and mocks.

3. Original study notes

Review gated

Explanations are authored as PrepAI originals and checked before student surfaces.

4. Retrieval actions

Actionable

Students move from locator to formula recall, DPP, PYQ-style practice, and paper generation.

Source safety rules

What the portal can and cannot do

The study-material feature is designed to turn source coordinates into retrieval, not to mirror official textbooks.

NCERT is used as source locator and structure authority.

PrepAI does not reproduce textbook passages in commercial study surfaces.

Practice, DPP, mocks, and assignments use reviewed PrepAI content only.

PYQ text remains review-gated until extraction, answer validation, and source metadata pass.

Ready for retrieval?
