One integrated computer vision platform for labeling, curation, QA, and datasets management. Lightly is built for ML engineers and organizations scaling computer vision.
Two products, one pipeline. LightlyStudio is the data hub - curate, annotate, evaluate and visualize. LightlyTrain turns that data into production models
Everything you index is embedded automatically.
Filter by metadata, search by text or image, then run a sampling strategy - diverse coverage, deduplication, outlier detection, similarity, or class balancing - to keep only the subset worth labeling.

Create, edit and review annotations right where you work, whether that's a quick check or a full QA pass.
Every labeled object gets its own embedding, so you can search and cluster objects the same way you search whole images. Bring in SAM3 or a LightlyTrain model to auto-label the easy cases first.

Run an evaluation against ground truth and get per-sample metrics plus a confusion matrix, no separate script required.
Sort by false positives, false negatives or mIoU to jump straight to the samples your model gets wrong.

Install ready-made plugins for SAM3 segmentation, LightlyTrain auto-labeling and video bounding box propagation, or register your own.
A plugin is a Python function with a form, so anything you can script, your whole team can run from the UI.

Invite your team and give each person a role that matches what they should touch.
Viewers browse and export, Labelers tag and annotate, Editors configure the workspace, Admins manage it all.

Export annotations or filenames straight from the grid, or automate it in Python. Export the full dataset or just a filtered subset by tag or query.

Lightly’s suite of tools integrates into your existing machine learning pipeline, facilitating data curation, model training, and deployment processes.

Teams shipping Physical AI use Lightly to get from raw sensor data to a deployed model — in the field, on the line, and at the edge.
