# Prompts Overview

> Prompts are optional recurring questions delivered to participants on a schedule.

Prompts are recurring questions or tasks delivered to participants at scheduled times throughout your study. They're a powerful way to collect longitudinal data in NeuroFusion, but they are **optional** at the quest level.

## What Is a Prompt?

A prompt is a question with:

* **Prompt text** — the question or instruction shown to participants
* **Response type** — how participants answer (Yes/No, Text, Number, Number Range, or Custom Options)
* **Category** — organizational tag (e.g., Mental Health, Productivity)
* **Schedule** — which days, what time window, and how often the prompt fires
* **Notifications** — whether to send push notifications for this prompt
* **Conditional rules** (optional) — only fire if a previous answer meets a condition

## Requirements

* Quests can have **zero prompts**
* There is no upper limit on prompts per quest

If your study only needs onboarding, experiments, recordings, health data, or analysis scripts, you can leave prompts empty and still create the quest.

## Billing

See the [Pricing](https://usefusion.ai/pricing) page for details on prompt-based billing.
