Bring a CSV. Leave with a plan.

An agent reads your file and proposes the data model one decision at a time, with the evidence from your own rows.

Most tools guess your data model.

This one shows its work.

Every decision carries the rows that made it.

Switch off what you disagree with.

Repeating values become their own table. Cells that hold several values become a many-to-many link. Turn a decision off and the diagram redraws at once.

The agent is rule-based, not a language model: the same file always gives the same plan, and it works with no key and no internet. It makes the plan; Ask2App builds the app from it.

Free. On your computer. Nothing leaves it.

Your file stays in memory on your machine, and the source is yours to keep.
