> An AI chat lands in the Builder so you can work with it while building a survey; condition operators behave the same way across question types, and answer options stop reshuffling after publication.

## AI improvements

### AI chat in the Builder

A conversational interface is now available directly inside the [Builder](/en/builder/overview), so you can interact with the AI in real time while creating a survey, exploring ideas and adjusting content without leaving your workflow.

### Loading state for AI follow-ups

AI-generated follow-up questions on open-ended responses now show a loading state while the system processes the next step.

### Improved AI performance

AI interactions are faster and more consistent when generating or updating survey content.

## Improvements

### Condition handling

Condition operators behave more consistently and predictably across different question types, making [logic flows](/en/logic/conditions) easier to build and maintain.

## Fixes

### Matrix rendering

Matrix questions without rows could break the interface. Rendering is now stable and no longer causes errors during survey creation.

### Option rotation in live studies

Answer options kept reshuffling after a study was published, including locked options. Options now stay stable and respect the rules you defined.

### Condition inconsistencies

Fixed inconsistencies in how condition operators behaved across question types, for more predictable behavior during survey execution.
