Seam is a plugin for Adobe Photoshop. It creates, edits, and upscales images directly in the document you have open. Results come back as normal layers, ready to keep working on. No exporting, no switching between apps.

You choose the AI model yourself. Gemini, GPT Image, FLUX, Reve, and dedicated upscaling models are all available from one dropdown, so you can pick the right one for each image without leaving Photoshop.

Preview first, then commit. Get a quick, low-cost preview to check the direction, and only generate the full-resolution image once it looks right.

Selections carry over. Work on a selected area and the result is masked to it. Auto Mask can also separate the main object for you, so it lands on its own layer mask.

Reuse what worked. Save your favorite prompts as presets, and reload the exact model and settings from any layer you generated earlier.

Each image above is the one before it, changed by a single sentence. In Photoshop, every result lands on its own layer, so no step destroys the last one.

1. Selections steer edits. Select a region and the result returns masked to exactly that region.
2. Preview before commit. A small draft first — the full-resolution render only once the direction is right.
3. Auto Mask, in beta. Seam reads the subject out of your prompt and attaches an object mask to the new layer. If that fails, you still keep the image.
4. Layers remember. Model, prompt, seed, and settings are stored on the layer itself — load them back months later.
