Generate Entity-Relationship (ER) diagrams from SQL `CREATE TABLE` statements instantly. Get AI-powered insights on schema design, query optimization, and relationship interpretation.
Input one or more SQL `CREATE TABLE` statements below.
Copy and paste one or more `CREATE TABLE` SQL statements into the input editor. The tool is designed to understand common table, column, and constraint definitions.
Click "Generate ER Diagram." The tool parses your SQL client-side and instantly renders a visual Entity-Relationship (ER) diagram using Mermaid.js, showing tables, columns (with PK/FK), and relationships.
Our AI provides conceptual advice on database normalization, indexing strategies, and best practices for schema design, helping you build robust and efficient databases.
The AI also offers conceptual suggestions for optimizing common queries on your schema and interprets the likely meaning of relationships between your tables (e.g., one-to-many, many-to-many).
Examine the generated diagram and Mermaid code. Copy the Mermaid code to integrate into your documentation, or use the AI insights to refine your database design. Your data remains private.
All SQL parsing, diagram generation, and AI analysis are performed securely and instantly within your browser. Your SQL code is never uploaded to our servers, ensuring complete privacy and security.
Visually plan and refine your database schema before implementation. Quickly see how tables and relationships are structured.
Paste SQL from an existing database to quickly visualize its structure, making it easier to understand complex legacy systems or new projects.
Students and aspiring developers can use it to see how SQL `CREATE TABLE` statements translate into a visual model, reinforcing learning.
Generate diagrams for pull requests or project documentation, making it easier for team members to understand database changes or overall structure.
Get AI suggestions on how to optimize queries based on your schema's structure, helping you write more efficient database interactions.

Go beyond basic visualization with intelligent AI advice on schema design best practices, conceptual query optimization, and intuitive interpretation of table relationships.
All SQL parsing, diagram generation, and AI analysis are performed directly in your browser. Your sensitive database schema is never uploaded to our servers, guaranteeing complete privacy and security.
Designed for simplicity, our tool allows anyone to visualize database schemas quickly. No complex installations or technical knowledge required – just paste your SQL and get insights.
A: This tool takes SQL CREATE TABLE statements as input and automatically generates a visual Entity-Relationship (ER) diagram. It also provides AI-powered insights into schema design best practices, conceptual query optimization, and interpretation of relationships between tables.
A: The tool primarily supports standard SQL CREATE TABLE statements. It parses table names, column names, data types, PRIMARY KEY constraints, and FOREIGN KEY REFERENCES to build the ER diagram. Complex or non-standard SQL syntax might not be fully supported for parsing.
A: It parses your SQL input client-side and converts it into Mermaid.js syntax, which then renders a visual ER diagram directly in your browser. This diagram shows tables, their attributes, and relationships.
A: Our AI offers conceptual advice on database normalization, indexing strategies, data type choices, and common database design pitfalls. It also suggests how to optimize queries for common operations and interprets the meaning of relationships between tables.
A: Yes, our AI Database Schema Visualizer tool on HowToGet.in is completely free to use. There's no account sign-up, no credit card required, and you get unlimited usage.
A: Absolutely. All SQL parsing, diagram generation, and AI interactions are performed client-side in your browser. Your SQL code is never uploaded to our servers, ensuring your privacy.
