Node Library | OvalBee

Each page in the Node Library describes one node: what it does and when to reach for it, what has to exist before it runs, what happens step by step, answers to common questions, and its exact inputs and outputs. Open a node’s page from the app with the Documentation link in the node’s sidebar.

Categories

The sidebar groups nodes the same way the node picker in the editor does.

Category	What its nodes do
Import	Bring images and videos into a dataset: upload files or pull a public dataset.
Datasets	Point a flow at a dataset, copy, move and merge data, create ontologies, and profile a dataset’s quality.
Assets	Remove assets and transform annotations: keep some classes, one shape per class, rename classes.
Filter	Keep or drop images, labels and predictions by rules.
Sample	Take random samples, split into training and validation, collect images worth a second look.
Label	Labeling and review stages, and automated quality checks between them.
Train	Fine-tune detectors on your data.
Predict	Run a pretrained or trained detector over a dataset.
Evaluate	Score predictions against ground truth, compare models, recommend training settings.
Models	Export and upload models, and embedding-based tools for duplicates, outliers, label errors and dataset maps.
Flow control	Start a chain of nodes, wait for branches to finish, stop a chain.
Supervisely	Import from Supervisely and run Supervisely labeling queues and jobs from a flow.

Reading a node page

Badges at the top mark nodes that need a GPU worker, and nodes that run in their own Docker image — their first run can take longer while the image is pulled.
Prerequisites list what must already exist, such as a labeled dataset or a secret with credentials.
Inputs and Outputs are generated from the node’s definition, so they always match what you see in the sidebar. The JSON config at the bottom is the same interface in machine-readable form.
