Swap | Hylope Docs

The Swap tab changes one thing in a photo and keeps everything else: the product, the outfit, the people, or the composition. Every swap starts from a Scene Photo, and the input mode decides what gets replaced.

ProductReplace a product while preserving the original pose, angle, orientation, and placement.

Product In HandReplace a hand-held product and allow the grip, fingers, and hand pose to adapt naturally.

OutfitReplace only the clothing worn in the scene while keeping the person identity unchanged.

CharacterReplace the people in the scene with provided characters while keeping pose, lighting, and framing.

Composition (Beta)Use any reference image to transfer framing, crop, zoom, and overall composition onto the scene subject.

How a swap works

Choose the input mode
Pick it under Input Mode in the settings panel. The model list follows the input mode.
Load the scene
Drop the photo to change on Scene Photo. It takes an image.
Load what goes in
The second slot is named after the input mode: see the table below.
Generate
The prompt is optional. Create writes the swap instruction, and anything you type is added to it as extra direction.

Input mode	Second slot	What changes
Product	Product Asset	The product, at the same pose, angle, orientation and placement.
Product In Hand	Product Asset	The held product. The hand, fingers and grip adapt to it.
Outfit	Outfit Reference	The clothes only. The person stays the same.
Character	Character 1 and more	The people, keeping pose, lighting and framing.
Composition	Composition Reference	The framing, crop, zoom and point of view, taken from any reference image.

The Outfit Reference, Composition Reference and Character slots also take a snippet. Its text then describes the outfit, the framing or the person in place of an image.

Character

Character replaces the people in the scene with the characters you load. The input panel offers up to five Character slots, fewer when the model accepts fewer images.

With several people in the scene, the characters replace them from left to right: Character 1 takes the leftmost person.
In the prompt, name them @character1, @character2 and so on.
Removing a character on the Input card moves the next ones up, and their mentions in the prompt follow.

Coherent Lighting

Coherent Lighting asks the model to match what it inserts (the product, the outfit or the characters) to the light of the scene: shadows, reflections and color. It has no effect in Composition.

Models

Each input mode offers its own models. The default model is ChatGPT Image 2.5 Flare.
