chaiNNer is a node-based image processing application that lets users build visual workflows by connecting processing nodes.
Originally developed as an AI upscaling tool, it has grown into a flexible image processing environment for more general tasks, including batch image work and video-related processing. The software is cross-platform, provides an integrated Python environment, and uses a dependency manager to install supported backends and frameworks.
This is free and open source software.
Key Features
- Uses a visual node editor to create customizable image processing pipelines.
- Supports AI upscaling and other image processing workflows.
- Can batch process folders of images.
- Includes nodes for video input and video output workflows.
- Supports frameworks including PyTorch, NCNN, ONNX, and TensorRT.
- Can automatically download and use an isolated integrated Python build.
