QUESTIONS

Frequently asked questions.

Everything you need to know about the platform, pipelines, billing, and formats.

Can Synthmark handle polygon segmentation and boxes in the same project?

Yes. Synthmark lets you combine box, polygon, and keypoint annotations inside a single project under the same label schema, review queues, and export configurations.

Does the platform include AI-assisted labeling?

Yes. Annotators can use integrated bounding box detectors (YOLOv9) and interactive segment-anything models (SAM) to generate pixel-level segmentations in seconds. All AI suggestions remain subject to reviewer verification.

Which export formats are supported?

Synthmark natively exports to COCO, YOLO, Pascal VOC, and a comprehensive custom JSON format, ensuring easy consumption by PyTorch, TensorFlow, or custom vision loaders.

How does the review workflow function?

Images flow from labeling to a dedicated review queue. QA Leads inspect annotations, check them against instructions, and either approve or reject with comments, returning them to the annotator's workspace.

Stop losing hours to broken annotation workflows.

Teams using Synthmark ship verified datasets faster — with built-in QA loops and zero export rewrites.
