LiDAR point-cloud labeling, multi-camera sensor fusion, robot demonstration trajectories, world-model rollouts and embodied interaction logs.

An AI work partner that turns a sentence into finished office deliverables
Describe a task in one sentence; WorkBuddy plans the workflow, selects the tools it needs, creates the files and keeps the process and results available for review.
The agent builds a research plan, cross-checks information across sources and delivers a structured report with actionable recommendations, which the vendor says can land within ten minutes.
Produces reports, presentations, spreadsheets and documents, with Markdown, Word and PowerPoint export for downstream editing.
Brings chat, documents, email, meetings and knowledge bases together, with listed integrations for Slack, Telegram, Notion, Google Drive, GitHub, Jira and Linear.
