$8/month

Save $9/mo vs. individual tools

Three steps. Zero friction.

No integrations to configure, no pipelines to set up. Just paste SQL and get results.

01

Paste your SQL

Copy any SQL query — a simple SELECT, a complex CTE with window functions, a stored procedure. No setup required.

02

AI analyzes it

Our AI engine parses the query structure, identifies patterns, detects anti-patterns, and generates insights specific to your code.

03

Get actionable results

Receive documentation, optimization suggestions, code review feedback, or plain-language explanations — ready to use or share.

Why not just use ChatGPT?

Generic tools cost you time.

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 enterprise SQL patterns, complex CTEs, or stored procedures.

🎯

SQL Querywise

Built exclusively for SQL — understands window functions, indexes, and real anti-patterns.

ChatGPT / Generic AI

You have to explain business context to a generic model every single time.

Built by a Data Engineer, for Data Engineers.

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Agile teams, and managing complex SQL codebases — I kept running into the same problem: SQL documentation is always outdated, query reviews take too long, and explaining data logic to non-technical stakeholders is a constant time sink.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.
