Product Positioning

What makes it different

Graph/node workflows let you compose, reuse, and iterate on complex diffusion pipelines with maximal control.

Primary use case

Build and run custom diffusion workflows (from simple prompts to complex multi-step pipelines).

Core problem it solves

Most image generators hide control behind presets, making advanced pipelines hard to reproduce or customize. Switching between tools for steps like conditioning, sampling, upscaling, and post-processing is slow and error-prone.
