Frequently asked questions
Quick answers to the things people ask most. Don't see yours? Reach out from the contact section on the homepage.
Do I need an account to use VisoLabel?
No. Download it, open a folder of images or videos, and start annotating. The free version runs entirely on your machine. An account is only needed to manage a paid license.
Where does my data live?
On your computer. VisoLabel is local-first: annotations, datasets, and trained models all stay on disk unless you explicitly choose to push a training job to Google Colab.
What's the difference between SAM2 and SAM3?
SAM2 is interactive — you click an object and it predicts a mask. SAM3 is fully automatic — point it at a folder and it labels everything in bulk. Free includes unlimited SAM2; SAM3 is metered on Free and unlimited on paid plans.
Do I need a GPU?
Not for annotation — SAM2 and SAM3 run fine on CPU. For local training a GPU is strongly recommended, but you can train on Google Colab instead if you don't have one.
How much cloud training can I do with Google Colab?
Google Colab offers limited free GPU access. Google Colab Pro costs approximately $10 per month and currently includes 100 compute units.
As a practical reference, 100 compute units may provide around 50 hours on an NVIDIA T4 GPU. For RF-DETR, this can generally cover several training runs on small or medium datasets.
Actual usage depends on the assigned GPU, dataset size, model, resolution and number of epochs. Google displays the current compute-unit consumption rate before you start the runtime.
Can I import labels from another tool?
Yes. VisoLabel imports COCO, YOLO, and Pascal VOC annotations so you can pick up where you left off. See the Projects & data guide.
What model formats can I export?
Models export to PyTorch, ONNX, and TensorRT. Datasets export to YOLO, COCO, and Pascal VOC. See Export & deploy for details.
Does training on Colab send my data to the cloud?
Only if you choose the Colab compute target. In that case your dataset is packaged and uploaded to your own Colab session. Local training keeps everything on your machine.
Can I use the models commercially?
Yes, with a Pro or Enterprise license. The Free plan is for non-commercial use only. Supported models use permissive MIT or Apache 2.0 licenses, subject to the terms of the applicable model license.
