Use AI to document SQL que
From documentation to performance optimization — purpose-built AI tools that fit into your existing workflow.
Instant SQL Documentation
Paste any SQL query and get structured technical documentation in seconds — table descriptions, column explanations, query purpose, and data lineage.
Performance Intelligence
Analyzes your queries for performance bottlenecks, suggests missing indexes, recommends refactoring patterns, and estimates execution cost improvements.
Automated Code Review
Runs a full SQL code review against best practices — naming conventions, security vulnerabilities (SQL injection patterns), style consistency, and maintainability.
SQL for Non-Technical Teams
Translates complex SQL queries into plain business language. Share with stakeholders, product managers, or analysts without needing a Data Engineer in the room.
Cross-Dialect SQL Migration
Convert SQL code between T-SQL, PL/SQL Oracle, PostgreSQL, MySQL, BigQuery, and COBOL. Produces a full migration report with incompatibility warnings and validation test cases.
Deep SQL Data Analysis
Goes beyond syntax — maps data flow, identifies performance risks, extracts statistical patterns, and delivers an optimised rewrite validated against 241 proprietary rules.
No integrations to configure, no pipelines to set up. Just paste SQL and get results.
Copy any SQL query — a simple SELECT, a complex CTE with window functions, a stored procedure. No setup required.
Our AI engine parses the query structure, identifies patterns, detects anti-patterns, and generates insights specific to your code.
Receive documentation, optimization suggestions, code review feedback, or plain-language explanations — ready to use or share.
ChatGPT and Claude are great at everything — which is why they're mediocre at SQL. SQL Querywise was built for one thing: making Data Engineers faster.
ChatGPT / Generic AI
You write a long prompt, iterate 3 times, format the output by hand.
SQL Querywise
Paste your query. Result ready in seconds.
ChatGPT / Generic AI
Different output every time — you never know what you'll get.
SQL Querywise
Consistent format every time: docs, reports, structured suggestions.
ChatGPT / Generic AI
ChatGPT doesn't know your organisation's SQL rules — it gives generic advice that ignores your naming conventions, index standards, and security policies.
SQL Querywise
Powered by 241 dialect-specific rules across T-SQL, PL/SQL, PostgreSQL, MySQL and BigQuery — every analysis enforces YOUR standards.
ChatGPT / Generic AI
You have to explain business context to a generic model every single time.
SQL Querywise
Explainer translates complex SQL into business language — share directly with your PM.

João Pedro Carvalho — Technical Lead & Data Engineer
After years working as a Technical Lead in enterprise data environments — building Business Intelligence platforms, leading Agile teams, and managing complex SQL codebases — I kept running into the same problem: SQL documentation is always outdated, query reviews take too long, and explaining data logic to non-technical stakeholders is a constant time sink.
SQL Querywise was built to solve exactly those problems. These are the tools I wished existed when I was spending hours documenting stored procedures or explaining window functions to a product manager. Now they do.
