Gayatri Chemistry Tutor

NCERT-Aligned Adaptive AI Tutoring with Deterministic Evaluators & Fine-Tuned Models

System overview

Architecture & Core Mechanics

Unlike generic LLM wrappers that hallucinate chemical equations or give shallow answers, Gayatri Chemistry Tutor pairs a neural language model with a deterministic adaptive learning engine. It features persistent student mastery tracking, structured answer evaluation for stoichiometry and thermodynamics, concept-aware RAG, and an append-only evidence ledger.

Engineering Highlights & Capabilities

  • ✓
    17-Stage Fine-Tuning Curriculum: Trained on Colab T4 with Qwen2.5-1.5B-Instruct using LoRA/PEFT across thermodynamics and inorganic chemistry.
  • ✓
    Deterministic Answer Evaluators: Custom symbolic checks for numerical tolerances, stoichiometry, formula normalization, and MCQ without naive string matching.
  • ✓
    Root Misconception Diagnosis: Actively diagnoses conceptual flaws (e.g. standard enthalpy of formation, logic inversion) and directs remediation.
  • ✓
    Portable Windows Desktop Package: Single-folder portable executable with embedded Python runtime and GGUF inference backend.
