Kili Technology

Labelbox

Best overall

For most everyday users, neither Kili Technology nor Labelbox is the right tool—they are enterprise-grade data annotation platforms, not consumer apps. Kili wins for teams needing deep medical imaging support and extreme customization, while Labelbox is better for teams that want a polished data catalog and easier cloud storage integration. The single biggest difference: Kili offers best-in-class DICOM/medical support, whereas Labelbox provides a more accessible freemium entry point.

Common questions

Can I use Kili Technology or Labelbox on my phone?

No. Neither tool has a mobile app. Both are designed for desktop/laptop use with a web browser.

Which is better for a small startup with no technical team?

Neither is ideal. Both require technical skills (Python, APIs). Labelbox's free tier is easier to start with, but you'll still need someone who can code.

Is Kili Technology better than Labelbox for medical imaging?

Yes. Kili has dedicated DICOM support and is built for medical workflows. Labelbox supports DICOM but lacks the same depth.

Which tool is cheaper for a hobbyist?

Labelbox's free tier is the only no-cost option. Kili's free trial is time-limited, and paid plans are custom-priced, likely too expensive for hobbyists.

Do these tools work with cloud storage like Google Drive?

Both connect to AWS S3, Google Cloud Storage, and Azure Blob, but not directly to Google Drive or Dropbox. You'll need to move your data to a cloud bucket.

Kili Technology and Labelbox are both powerful enterprise annotation tools, but Labelbox wins for everyday teams thanks to its free tier and easier data management.

If you're a non-technical person looking to label data for AI, these tools are overkill. Start with a simpler, cheaper option like Roboflow or Supervisely. But if you must choose between these two, Labelbox's free tier and slightly easier setup make it the better pick for most teams.
