Custom column creation — AI custom column creation dialog in Lantern

A dialog for adding a custom column in Lantern, where the content of each cell comes from LanternAI instead of a data source.

The dialog asks for three things: a name, a type (text or true/false), and a plain-language instruction for what LanternAI should fill in. The placeholder shows what a good instruction looks like: show their last workplace and the date they left, in the format Workplace / Date. A line under the field asks people to describe the format as well as the content.

It opens over the contact visitors table, so the new column lands right where it’s needed.
