freenandes/actuallyexplain — reverse-engineered prompt

Build me a simple browser app where I can paste a PostgreSQL query and instantly see what it is trying to do, without needing a database connection. I want a big SQL editor on one side, then a visual flow diagram that breaks the query into steps like sources, joins, filters, groups, CTEs, and outputs, plus a plain English dictionary style panel that explains whatever part I click.

The goal is to help someone sanity check complex or AI generated SQL before running it, so make it feel clear and trustworthy, not overly technical. If the query has recursive references or deeply nested logic, show that in the graph in a way that is still readable. Add a small About section that explains the tool is for understanding logical intent, not measuring query performance. Keep it as a clean single page app, and if you need anything current, look up the docs online.
