Your attention is under siege. Take it back.
The average attention span has collapsed to 47 seconds. Screens are engineered to fragment focus. CyberSeals trains sustained attention through deliberate, distraction-free practice -- giving educators and learners the tools to reclaim what the digital world is stealing.
Start TrainingCyberSeals carries the curiosity of the seal, the discipline of the operator, and the trust of a seal of approval. We exist to order the chaos of a distracted world -- training learners to master their attention and steward their minds with purpose.
Every modern app is designed to interrupt you -- notifications, ads, algorithmic feeds competing for your attention. A terminal strips all of that away. Dr. Gloria Mark's research at UC Irvine shows it takes 25 minutes to fully return to a task after an interruption. The terminal eliminates the interruption entirely. This is not nostalgia. It is neuroscience.
