THE PROBLEM
GST practitioners struggle with: (1) Tracking 250+ circulars across 32 website pages manually, (2) Time-consuming search through multiple PDFs, (3) AI hallucination risk with general-purpose tools, (4) Missing critical updates affecting client advisory. Professionals many times rely on informal groups for such information to get the same quickly
THE SOLUTION
Two-component system: (1) Three Python scripts automate downloading, metadata extraction, and organization of all GST circulars and notifications from gstcouncil.gov.in into year-based folders with standardized naming, (2) Upload organized circulars to Google NotebookLM to create a private, hallucination-free AI knowledge base with source attribution.
HOW IT WORKS
① Python Script 1 downloads PDFs from GST Council website → ② Script 2 extracts metadata to Excel (Circular No., Date, Subject, URL) → ③ Script 3 organizes files into year folders with naming pattern and also creates a single files for circulars and notifications → ④ Upload to NotebookLM → ⑤ AI-powered search with zero hallucination and source attribution
KEY BENEFITS
Time Savings ✓ Accuracy Coverage Cost
85-90% faster research Zero hallucination 100% of circulars Free tools
