A general-purpose AI agent that executes tasks, not just answers them
Give the agent a goal and it plans the steps, chooses tools, and works through the task in a cloud environment without constant supervision.
Produces finished artifacts such as slide decks, functional websites, small games, and formatted documents rather than raw text.
Runs broad, multi-source investigations and compiles the findings into a structured report.
Generates images, video, and music as part of a larger task or as standalone outputs.

Browse and control Chrome with head movements while AI watches your posture
Vertical head motion scrolls the page while horizontal motion switches tabs, giving you a hands-free way to navigate Chrome.
The head-tracking model runs in your browser against the webcam feed, so detection happens locally rather than on a remote server.
Neckium notices when your sitting posture drifts and sends a notification prompting you to straighten up.
It also flags prolonged sitting, encouraging regular movement breaks during long work sessions.
