Free data tools
Try it straight away: open a tool below, paste a schema or drop in a spreadsheet, and read the result. These are small, single-purpose tools for the work that comes before the analysis — reading a schema, describing it, drawing it, moving a spreadsheet into a table. Each one runs entirely in your browser, so there is no signup, no upload, and your schema and your data never leave your machine.
CSV to SQL converter
Paste a CSV or upload a CSV or Excel file and get CREATE TABLE plus INSERT statements for PostgreSQL, MySQL, SQL Server, SQLite or generic ANSI SQL, with column types inferred from your values.
ER diagram generator
Paste CREATE TABLE statements and get an entity-relationship diagram — tables, columns, primary and foreign keys, and the lines between them. Export the SVG or the Mermaid erDiagram. Runs in your browser.
Data dictionary generator
Paste SQL CREATE TABLE statements or upload a CSV or Excel file and get a clean, exportable data dictionary — tables, columns, types, keys and business meanings. Runs in your browser.
The one-stop AI data analyst that knows your schema.
One place from question to finished work: the SQL, the chart, a dashboard your whole team can open, and a report that emails itself every morning. It learns what your columns mean, so nobody explains a field twice. Start free with one database plus Google Sheets, or take 14 days of Pro with no card.
Every new account starts on a 14-day Pro trial with no card. After it lapses, the free tier stays free.
