# set_adaptive

> Enable or disable AI follow-up questions ('adaptive intake') on a text field, with a natural-language instruction describing what a complete answer contains. When a respondent answers too thinly, the form asks up to max_followups clarifying questions inline.

## Ask your assistant

- "Add an AI follow-up to the description field - a complete answer mentions budget, timeline and scope. Allow 2 follow-ups."

The hero feature. `instruction` is required when enabling — it defines *complete*, and the AI probes only for what's missing. `placement` decides where follow-ups render in multistep layouts. Full behavior, caps and degrade rules: [AI follow-ups](/help/adaptive/ai-follow-ups).

## Inputs

- `form_id` (string): Form id (authenticated). From create_form/list_forms.
- `draft_token` (string): Draft token (anonymous drafts, before sign-in). From create_form's draftToken.
- `key` (string, required): Field key (must be short_text or long_text)
- `enabled` (boolean, required)
- `instruction` (string): Required when enabling, e.g. 'a complete answer mentions budget, timeline and scope'
- `max_followups` (integer (min 1, max 3)): 1-3, default 1
- `placement` ("inline" | "step"): Form-wide, multistep layouts only: where follow-ups render — 'inline' under the field, or 'step' as their own interstitial screen after Next (default: step for focus layout, inline for paged)
