The honest brief
Kili Technology
Combines human-in-the-loop annotation with LLM-as-a-judge evaluation in one workflow, instead of labeling-only or eval-only tooling.
- Multi-modal annotation
- Built-in QA and review workflows
- LLM evaluation and RLHF support
- On-prem and private-cloud options
- Enterprise-oriented complexity
- Smaller than Scale or Surge
- Managed labeling costs extra
Label Studio
One UI labels every modality — image, text, audio, video, time-series — where most tools specialize in just one.
- Covers all data modalities in one tool
- ML backends pre-label to speed review
- Strong SDK, webhooks, open APIs
- Free community edition; clean Enterprise path
- Self-host setup needs DevOps maturity
- Advanced QA/consensus gated to paid tiers
- Less CV-specialized than CVAT or Encord
