AI composer

Purpose and placement

A multiline prompt hands the user’s request to an external AI service without pretending to be an in-app chat.

Anatomy

• Mode control
• Growing textarea
• Named send action

Contract

States and feedback

• Two-row starting textarea
• Grows up to five line heights
• Beyond maximum: internal text scroll
• Send clears mode and prompt before navigation

Interaction and composition

Switching between search and AI is a mode change, not a submitted request. Sending places the prompt into the provider URL and navigates the current tab. No assistant answer, transcript or inference occurs in Startboard.

Responsive behavior

Textarea shrinks within the same composer cap. Send remains at the lower right; reserve input padding so text does not overlap it.

Accessibility contract

Both mode and send buttons have aria-labels. The textarea’s provider placeholder is not a persistent label. Indicate the external destination in help text as a recommended improvement.

Known implementation gaps

Prompt text enters an external URL and provider history. Provider availability, account requirements and deep-link behavior are not verified by the captures.
