Key Features

  • •Natural language to SQL query translation
  • •3-layer caching system (Exact, Semantic, LLM)
  • •Auto error correction for query refinement
  • •Multi-LLM support (Claude, GPT-4, Cohere, Mistral, Gemini)
  • •Multi-database support (PostgreSQL, MySQL, SQLite, SQL Server)
  • •Redis-based query persistence
  • •Full TypeScript type safety
  • •CLI and SDK interfaces for flexible integration

NTTP (Natural Text Transfer Protocol) transforms how developers interact with databases by enabling natural language queries. Instead of writing complex SQL, simply ask questions in plain English.

Live Demo

Try NTTP yourself with the interactive demo: nttp.appliedtensors.com

Experience natural language database queries in action without any setup required.

How It Works

NTTP uses a sophisticated 3-layer caching system to optimize performance:

  1. Exact Cache: Instant results for identical queries
  2. Semantic Cache: Matches similar questions using embeddings
  3. LLM Layer: Generates SQL when no cache hit exists

Key Capabilities

Multi-LLM Architecture: Choose from Claude, GPT-4, Cohere, Mistral, or Gemini based on your needs and budget.

Auto Error Correction: When queries fail, NTTP automatically analyzes errors and refines the SQL, eliminating manual debugging.

Universal Database Support: Works with PostgreSQL, MySQL, SQLite, and SQL Server through unified interfaces.

Production Ready: Redis persistence ensures queries survive restarts, while TypeScript provides complete type safety.

Use Cases

  • Rapid Prototyping: Query databases during development without writing SQL
  • Data Analytics: Enable non-technical team members to explore data
  • API Development: Build natural language interfaces for database access
  • DevOps: Quick database inspections using plain language
