# QueryInsights

> Make every query faster. With AI.

QueryInsights is an AI-powered SQL performance and query optimization tool. It watches your live database workload, finds the slow queries that hurt performance, and turns every pattern into actionable query rewrites and index recommendations.

## What it is

An AI-powered SQL performance and query optimization tool for teams running PostgreSQL, MySQL, and Trino. It identifies the slow queries and query patterns slowing your database down and tells you, specifically, how to fix them — query rewrites for individual statements and index/schema recommendations for the whole workload.

- How It Works: /how-it-works

## What it does

- Detects slow queries by capturing the live SQL workload via webhooks or pollers, without sitting in the request path
- Normalizes thousands of query variants into the small set of patterns they really represent
- Ranks query patterns by impact so the most valuable optimizations show up first
- Generates per-query rewrite recommendations grounded in your real table definitions
- Generates workload-level index and schema recommendations that benefit the whole access pattern

## Supported engines

- PostgreSQL
- MySQL
- Trino
- Extensible to other SQL engines

## How recommendations work

Two complementary kinds of AI advice, deliberately non-overlapping:

- Per-query rewrites: how to write one specific slow query better (rewrites, predicate ordering, projection scope, engine-specific tuning). Never schema or index advice.
- Workload-level schema: index recommendations, layout, and schema changes that benefit the entire workload. Never per-query rewrites.
