Katalist

Overview

Katalist is an AI-powered video generation platform purpose-built for performance marketing teams. It enables marketers and agencies to transform existing winning creatives into new, high-performing ad variants without going back into production. At the core of the platform is its product swap engine, which allows users to replace a product inside a previously successful video while preserving the original structure, motion, and narrative. This turns every well-performing piece of content into a reusable template for ongoing creative testing and scaling.

The platform is organized around a three-part workflow: Surface, Recast, and Scale. In the Surface phase, users import a proven video script or use Katalist's one-click brief-to-video feature to generate an initial draft. During Recast, the AI handles tasks such as swapping a product with a new SKU, replacing characters or voices, and localizing the video for new markets through lip-sync adjustments. Every modification is driven by natural language prompts, so a client request like “swap the orange serum bottle with this black bottle at Frame 1” becomes a simple text command rather than a full re-shoot or re-edit. Finally, Scale lets users expand a single winning video across a portfolio of products, SKUs, and clients from one central canvas.

Katalist also addresses the operational side of creative production. Designed by marketers and built for agencies, it provides a centralized workspace where teams can manage creative assets for every client, ship more variations per brief, and maintain consistent quality without adding headcount. The platform supports UGC-style videos and full product promo videos, with examples showing production timelines of minutes to hours rather than weeks. Performance teams can launch dozens of ad variants in a short period, reducing the impact of ad fatigue and extending the lifespan of successful creative.

By combining AI-driven video editing, prompt-based asset swapping, and scalable workflows, Katalist helps performance teams keep their ad pipelines fresh, relevant, and always anchored to proven formats. Whether refreshing an underperforming account, rolling out a new product, or adapting content for a new geography, the platform aims to make creative iteration as fast and efficient as possible while eliminating the need for reshoots.
