Design prompts, collect model outputs, and curate gold responses at scale.

Review outputs next to your prompt. Rank, edit, and score with rubric-based labels so your team converges on a single source of truth.


Track every edit and decision. Roll back, compare versions, and keep provenance for each prompt and response.
Ship JSON for fine-tuning and evaluation harnesses. Sync through plugins to cloud storage, CI checks, and more.

Build and adjust your entire data project workflow without code, end-to-end, even while it’s running.
Deploy in your own environment for full control of data and workflows, from ingestion to export.
Users can leave comments on any region, frame, or message. Then, talk to QA to keep each thread open until resolved.
Add formats, integrations, or an ML model with a Python-based Ango plugin. Build the features you need, fast.
Human-guided suggestions accelerate work while keeping quality and oversight high.
Run custom validation code the moment work is submitted. Enforce rules and stop bad data from moving forward.
Create projects, add assets, query stats, and export annotations, all from code. Clean REST endpoints and a Python SDK that stays out of your way. All HIPAA, SOC II, and GDPR compliant.

Deploy Ango Hub on your own infrastructure, and run it completely air-gapped. Or run it on your own AWS, GCP, or Azure remote servers.
Receive events the moment they happen, such as asset created, label updated, or review passed. Then wire them into your training loop for rapid, active learning.
On all deployment versions of Ango Hub, your data is always encrypted, in rest and in transit, using the latest industry standards.
