Practical overview

When it fits

Use Vott when a project needs a desktop-oriented workflow for labeling visual assets and preparing object-detection data. Consider the archived, unmaintained status before adopting it for ongoing work.

Who it is for

  • Machine-learning teams preparing visual training datasets.
  • Annotators who need to label images or video frames and export the resulting data.

Documented uses

  • Label objects in images and video frames.
  • Set project tags and configure asset-source and export-target connections.
  • Import visual assets from supported local or cloud sources and export labeled data to configured targets.
Before you choose

Requirements & limits

  • The README lists local file system, Azure Blob Storage, and Bing Image Search as supported connection types.
  • The browser version cannot access local files and requires cloud-project imports and exports.
  • The repository documents native packages for Windows, Linux, and macOS, alongside running from source.
  • The repository is archived and the README states that VoTT is no longer maintained.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
