This spins up a local SQLite database with sample e-commerce data, auto-detects Ollama, OpenAI, or Anthropic, and opens a beautiful Chat UI on localhost:3000.

Demo Database Schema

The in-memory SQLite database is seeded with a comprehensive e-commerce schema to test complex queries against:

• users (id, name, email, country, created_at)
• products (id, name, category, price, stock)
• orders (id, user_id, total_amount, status, created_at)
• order_items (id, order_id, product_id, quantity, price)
• carts (id, user_id, created_at)
• cart_items (id, cart_id, product_id, quantity)

Try asking: "Who has items in their cart right now?", "Which category generates the most revenue?", "List all pending orders with amounts", or "Show me products under $100".

Anti-Hallucination Fallback (CANNOT_ANSWER)

AskChokro's engine uses a strict system prompt. If you ask a question about data that does not exist in the schema, the model will safely reject the prompt and return CANNOT_ANSWER instead of hallucinating fake tables or SQL.

Note: AskChokro can intelligently answer multiple disjoint questions in a single prompt by automatically combining them into scalar subqueries, ensuring you get all your answers in a single database round-trip without breaking the SQL driver.

Using Local Models (Ollama)

If you want to force a specific provider or model, use environment variables:

# Force Ollama with a specific model (ignores any API keys in your environment)
ASKCHOKRO_PROVIDER=ollama ASKCHOKRO_MODEL=qwen2.5-coder npx @digitalchokro/cli demo

# Force Anthropic
ASKCHOKRO_PROVIDER=anthropic ANTHROPIC_API_KEY=sk-ant-... npx @digitalchokro/cli demo

Why AskChokro?

If you've tried building "AI analytics" features into your SaaS, you know the drill:

• Python wrappers: You have to deploy a separate Python microservice just to run LangChain or LlamaIndex.
• Heavy BI tools: You look at tools like WrenAI or Superset, but they are full platforms. You just want a simple API endpoint to power a chat box in your own React app.
• Security nightmares: How do you guarantee the AI doesn't DROP TABLE or leak Tenant A's data to Tenant B?

AskChokro is different:

1. 100% TypeScript. Runs right in your Node.js backend (Next.js, Express, Fastify).
2. Zero-Config. The AskChokro wrapper auto-detects DATABASE_URL, OPENAI_API_KEY, and ANTHROPIC_API_KEY - and falls back to a local Ollama instance seamlessly when no keys are found.
3. AST-Level Security. We don't just rely on prompt engineering. We parse the LLM's SQL into an Abstract Syntax Tree (AST), strictly validate it's a read-only SELECT, and automatically rewrite the AST to enforce tenant scoping before executing it.

Quick Start (Next.js App Router)

Install the core engine and the Next.js adapter:

npm install @digitalchokro/askchokro @digitalchokro/adapter-nextjs @digitalchokro/provider-openai @digitalchokro/db-postgres

Create a route handler at app/api/ask/route.ts:

// app/api/ask/route.ts
import { AskChokro } from '@digitalchokro/askchokro';
import { createAskChokroRoute } from '@digitalchokro/adapter-nextjs';

// Auto-detects process.env.DATABASE_URL and process.env.OPENAI_API_KEY
const agent = new AskChokro();

export const POST = createAskChokroRoute(agent);

On your frontend:

const res = await fetch('/api/ask', {
  method: 'POST',
  body: JSON.stringify({ question: 'Who are my top 5 customers this month?' })
});

const { answer, sql, rows } = await res.json();
console.log(sql);  // "SELECT name, SUM(amount) FROM orders GROUP BY name ORDER BY SUM(amount) DESC LIMIT 5"
console.table(rows);

That's it. You just shipped AI data analytics.

Multi-Tenant Security (AST Rewriting)

When embedding AI in B2B SaaS, tenant isolation is the hardest problem. Naive string-appending (WHERE tenant_id = X) fails when the AI generates subqueries or complex JOINs that bypass the filter.

AskChokro uses a sophisticated AST Scope Rewriter.

import { DatabaseAgent } from '@digitalchokro/core';
import { PostgresAdapter } from '@digitalchokro/db-postgres';
import { OpenAIProvider } from '@digitalchokro/provider-openai';

const agent = new DatabaseAgent({
  db: new PostgresAdapter({ connectionString: process.env.DATABASE_URL }),
  ai: new OpenAIProvider({ model: 'gpt-4o' }),
  options: {
    tenantScoping: {
      enabled: true,
      column: 'organization_id',
      // Injects the current user's org ID from your request context
      getValue: (ctx) => ctx.orgId, 
    }
  }
});

With tenantScoping enabled, if the AI generates:

SELECT o.id, u.email FROM orders o JOIN users u ON o.user_id = u.id

AskChokro's AST rewriter physically intercepts the query, parses the syntax tree, and injects your tenant logic into every table reference before sending it to the database:

SELECT o.id, u.email 
FROM orders o 
JOIN users u ON o.user_id = u.id AND u.organization_id = 'org_123'
WHERE o.organization_id = 'org_123'

AskChokro dramatically reduces risk with a fail-closed design. See our Security Guide for full details on the 9-layer defense.

Accuracy Benchmarks

We test AskChokro against a rigorous, open-source dataset of 198 complex SQL scenarios.

(For full methodology, see our CI eval harness).

Current Limitations

AskChokro is designed to be simple and secure, which means it currently makes some intentional trade-offs:

• Multi-Part Questions Supported: AskChokro safely handles disjoint, multi-part questions by mapping them into unified scalar subqueries. However, the root AST must ultimately resolve to a single SQL tabular structure to ensure compatibility across all database drivers.
• No DML (Mutations): It is strictly read-only. INSERT, UPDATE, DELETE, and DROP are explicitly blocked at the AST level.
• Complex Aggregations: While it handles joins and basic aggregations well, extremely complex window functions or recursive CTEs might confuse smaller local models.

Coming Soon: WordPress Plugin

We are actively developing an official AskChokro WordPress Plugin. This will allow you to drop an AI data assistant directly into your WooCommerce dashboard with zero code.

The WordPress Roadmap:

• Phase 1: AskChokro Node.js Microservice (Pre-configured Docker container)
• Phase 2: WordPress PHP Plugin (Settings UI & Gutenberg Blocks)
• Phase 3: Automatic Tenant Isolation for Multi-Vendor setups

Read the Integration Architecture to learn how this works behind the scenes.
