Pika offers AI-powered video editing tools — including Pikaswaps, Pikadditions, and Pikaffects — that allow users to replace, add, or transform objects and characters within existing video clips. These tools are available to registered users on the web and iOS platforms.

Pikaswaps accepts a video clip and a text prompt or reference image as input, and outputs a modified video with specified objects, backgrounds, or characters replaced while preserving the original motion and lighting. Pikadditions takes a video and a text or image description and composites new characters or objects into the footage, automatically matching color and lighting. Pikaffects applies physics-defying visual transformations (such as melting, inflating, exploding, or 'cake-ifying' objects) to video subjects. These features were progressively introduced from Pika 1.0 (November 2023) through Pika 2.2 (February 2025).
