How It Works

Retrieval, Not Generation

IS Code.ai is a retrieval system — it finds and cites answers from specific Indian Standard codes. It is not a general-purpose AI chatbot. If the answer isn't in the ingested codes, it will tell you honestly.

What this system does

  • Retrieves exact clauses, tables, and definitions from ingested IS codes
  • Cites the specific clause number and page for every fact
  • Reproduces tables exactly as published — never summarizes them
  • Cross-references related clauses from the same standard
  • Tells you honestly when it cannot find the answer
  • Shows confidence level and source chunks for verification

What this system does NOT do

  • Not a general engineering chatbot — won't explain textbook concepts
  • Won't interpolate between table values or estimate
  • Won't perform structural calculations or design
  • Won't provide answers from IS codes not yet ingested
  • Won't interpret engineering diagrams or figures
  • Cannot sign off on designs — always verify with a licensed engineer
Examples

How to ask effective queries

✓ Ask this

What is the gradient for a 150 mm pipe per IS 1742?

Direct clause & table lookup

What does Clause 4.6.1.2 state?

Specific clause retrieval

What is the fixture unit value for a flush valve water closet?

Table value lookup

What is the minimum self-cleansing velocity for sewers?

Embedded engineering value

What are the requirements for testing drainage systems?

Multi-clause synthesis

✗ Not this

Explain Manning's formula

Textbook knowledge — not in context

Calculate the flow rate for my project

Requires engineering calculation

What is the definition of dead load?

May not be in the ingested IS code

Design a beam for 5m span

Structural design — not a code lookup

Compare IS 456 with ACI 318

Cross-standard comparison

Trust indicators

Understanding confidence levels

High Confidence

Exact match found in retrieved clauses. The answer is directly stated in the IS code text.

Medium Confidence

Partial match — a related clause was found but may not cover your exact scenario.

Low Confidence

No relevant data in retrieved context. The information may not exist in the ingested codes.

Classification

Answer types explained

Table Lookup

Data retrieved from a specific table in the IS code

Definition

Term definition from the terminology section

General

Prose-based clause retrieval and synthesis

Calculation

Values requiring computation from code provisions

Clause Not Found

The specified clause doesn't exist in this document

Verification

How citations & verification work

1

Retrieval

Your question is embedded and matched against our vector database of IS code chunks. The most relevant clauses and tables are retrieved.

2

Grounded generation

The AI is constrained to answer ONLY using the retrieved context. It cannot use its own training data. Every number and fact must come from the retrieved chunks.

3

Your verification

Every answer shows source chunks with clause numbers, page references, and match scores. Click “Show source chunks” to read the original text the AI used.

Important disclaimer

IS Code.ai is an engineering productivity tool. Outputs must never be used for actual construction or design without independent verification by a licensed professional engineer. The system retrieves information from digitized IS codes — it does not replace professional engineering judgment, local municipal bylaws, or the National Building Code.
