In simple English
This tool lets you ask questions about spreadsheets and databases in plain English. It writes the queries, runs the math, and turns the results into a web chart. You connect it to your own large language model and your data files. It runs inside your own Node.js program or on the command line. It costs nothing to download, but you pay your model provider for each question you ask.
What it is
AVA is a TypeScript framework for visual data analysis built for AI agents and developers. It loads CSV files, Excel workbooks, or database tables, profiles the data, and generates interactive chart files.

- Requires Node.js 22.13 or newer to run.
- Needs an external AI model key and active internet access for queries.
