WrenAI is an open-source Generative Business Intelligence (GenBI) agent developed by Canner, designed to enable seamless, natural-language interaction with structured data. It targets both technical and non-technical teams, providing the tools to query, analyze, and visualize data without writing SQL. All capabilities and integrations are verified against the official documentation and latest releases.

Key Capabilities

• Natural Language to SQL:
  Users can ask data questions in plain language (across multiple languages) and WrenAI translates these into accurate, production-grade SQL queries. This streamlines data access for non-technical users.
• Multi-Modal Output:
  The platform generates SQL, charts, summary reports, dashboards, and spreadsheets. Both textual and visual outputs (e.g., charts, tables) are available for immediate data presentation or operational reporting.
• GenBI Insights:
  WrenAI provides AI-generated summaries, reports, and context-aware visualizations, enabling quick, decision-ready analysis.
• LLM Flexibility:
  WrenAI supports a range of large language models, including:
  • OpenAI GPT series
  • Azure OpenAI
  • Google Gemini, Vertex AI
  • DeepSeek
  • Databricks
  • AWS Bedrock (Anthropic Claude, Cohere, etc.)
  • Groq
  • Ollama (for deploying local or custom LLMs)
  • Other OpenAI API-compatible and user-defined models.
• Semantic Layer & Indexing:
  Uses a Modeling Definition Language (MDL) for encoding schema, metrics, joins, and definitions, giving LLMs precise context and reducing hallucinations. The semantic engine ensures context-rich queries, schema embeddings, and relevance-based retrieval for accurate SQL.
• Export & Collaboration:
  Results can be exported to Excel, Google Sheets, or APIs for further analysis or team sharing.
• API Embeddability:
  Query and visualization capabilities are accessible via API, enabling seamless embedding in custom apps and frontends.

Architecture Overview

WrenAI’s architecture is modular and highly extensible for robust deployment and integration:

Component	Description
User Interface	Web-based or CLI UI for natural language queries and data visualization.
Orchestration Layer	Handles input parsing, manages LLM selection, and coordinates query execution.
Semantic Indexing	Embeds database schema and metadata, providing crucial context for the LLM.
LLM Abstraction	Unified API for integrating multiple LLM providers, both cloud and local.
Query Engine	Executes generated SQL on supported databases/data warehouses.
Visualization	Renders tables, charts, dashboards, and exports results as needed.
Plugins/Extensibility	Allows custom connectors, templates, prompt logic, and integrations for domain-specific needs.

Semantic Engine Details

• Schema Embeddings:
  Dense vector representations capture schema and business context, powering relevance-based retrieval.
• Few-Shot Prompting & Metadata Injection:
  Schema samples, joins, and business logic are injected into LLM prompts for better reasoning and accuracy.
• Context Compression:
  The engine adapts schema representation size according to token limits, preserving critical detail for each model.
• Retriever-Augmented Generation:
  Relevant schema and metadata are gathered via vector search and added to prompts for context alignment.
• Model-Agnostic:
  Wren Engine works across LLMs via protocol-based abstraction, ensuring consistent context regardless of backend.

• Databases and Warehouses:
  Out-of-the-box support for BigQuery, PostgreSQL, MySQL, Microsoft SQL Server, ClickHouse, Trino, Snowflake, DuckDB, Amazon Athena, and Amazon Redshift, among others.
• Deployment Modes:
  Can be run self-hosted, in the cloud, or as a managed service.
• API and Embedding:
  Easily integrates into other applications and platforms via API.

• Marketing/Sales:
  Rapid generation of performance charts, funnel analyses, or region-based summaries from natural language prompts.
• Product/Operations:
  Analyze product usage, customer churn, or operational metrics with follow-up questions and visual summaries.
• Executives/Analysts:
  Automated, up-to-date business dashboards and KPI tracking, delivered in minutes.

WrenAI is a verified, open-source GenBI solution that bridges the gap between business teams and databases through conversational, context-aware, AI-powered analytics. It is extensible, multi-LLM compatible, secure, and engineered with a strong semantic backbone to ensure trustworthy, explainable, and easily integrated business intelligence.
