About LearnHubPlay
LearnHubPlay is an independent software studio in Amsterdam. It designs and builds its own products: the TabNotes and FocusWall Pro Chrome extensions, the AgentReady web app, the TechCast Studio recording workspace, and the Tend and Sticky Companion apps for macOS.
Each of those products started with a problem the studio ran into in its own work: research context lost in browser tabs, distraction that hard blockers never fixed, tutorials that took longer to edit than to record, a Mac that slowed down without explanation. The guides on this site come from the same place, the research, testing, and design decisions behind those tools, written up so they are useful whether or not you ever use LearnHubPlay software.
Every guide is checked against its primary sources before it is published, and LearnHubPlay is responsible for its accuracy. The editorial policy explains how.
