# Field Hiding

> Hide irrelevant or sensitive fields so AskTable ignores those columns during AI queries, protecting privacy and improving analysis efficiency.

## Overview

Field hiding lets the AI ignore certain fields during queries. When a field is hidden, the AI does not consider its data when analyzing and answering questions — useful for excluding irrelevant or sensitive fields.

## How to use it

Open the **Data Overview** tab on the data source detail page, select a table on the left, and use the **Hidden** column in the field table to control fields individually:

1. Find the field you want to hide
2. Turn on the toggle in the **Hidden** column
3. The change takes effect immediately — the AI will ignore this column when answering questions

## Use cases

* **Exclude sensitive information**: hide fields with sensitive data so the AI does not use them when processing queries
* **Improve query efficiency**: hiding irrelevant fields reduces the amount of data the AI analyzes, improving performance
* **Simplify analysis**: hide auxiliary fields that don't need to participate in analysis

## Notes

* Once hidden, a field is fully ignored when the AI generates SQL and answers questions
* Hiding takes effect immediately — no extra save needed
* You can unhide a field at any time if you need it for analysis later
* If you want to mask a field rather than hide it entirely (for example, phone numbers or ID numbers), use the **Masking** column in the field table instead
