# Ingredients in prompts Type `@` in a prompt to insert an ingredient. Text ingredients can become spoken copy, captions, claims, or CTAs. Image ingredients can provide actor, product, logo, or style references. Video ingredients can provide b-roll, screen recordings, or reference footage. Use ingredients for anything that should be reusable or swappable. For example, instead of writing the hook text directly into every prompt, create `@Hook`. Instead of describing the product in every scene, use `@Product` where the product should appear. When you change an ingredient, review the scenes and elements that depend on it. Some changes can update copy or references directly; others require regeneration to produce a new visual output. {% embed url="" %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
