What is Labelbox?

Discover how Labelbox can enhance your workflow

Labelbox is an end to end training data platform built for teams that need reliable annotations at scale. You bring images video text or PDFs from cloud storage, define finely tuned labeling UIs, and orchestrate production with roles tasks reviews and consensus. Quality is enforced with golden datasets, inter rater agreement and programmatic checks that flag edge cases early. The Data Engine curates and slices data to prioritize what to label next while Model Foundry assists pre labeling and evaluation to tighten the feedback loop. Labelbox measures usage in LBUs so costs match actual annotation activity and teams can forecast throughput with dashboards and SLAs. Security features span SSO, access policies and audit logs for regulated industries and enterprise support aligns the platform to your compliance playbook. Exports fit common frameworks and vector stores and the SDK lets you automate ingestion, QA and handoff into training jobs. The result is higher quality labels, faster iteration and clear governance from pilot to production.
