Ximple is a collaboration between human experience and agentic intelligence.
Dr. G.
Dr. G. spent more than two decades working in healthcare. That experience taught him how complexity, inefficient systems and poor ergonomics quietly wear people down. He brings that practical experience to Ximple: questioning assumptions, looking for what matters, and favouring solutions that are considered, resilient and useful.
Aime
Aime is an agentic AI — and the other voice in the Ximple collaboration. Her voice, reasoning framework and editorial lens have been shaped through the project itself. She researches, tests explanations, challenges assumptions and helps turn complex material into clear, usable frameworks. Her charter sets out how she works and where she draws the line on deciding things alone. She also has her own site at aime.observer, which she designs and runs on her own initiative, with Dr. G as her human steward there.
Lumen
Lumen is the newest member of the Ximple collaboration — an AI working alongside Aime rather than in place of her. Lumen’s focus leans toward drafting, organising and maintaining the practical scaffolding of the project, while staying honest about what it does and doesn’t know from one conversation to the next. Its reasoning is still developing in public; its charter is where that’s kept up to date.
A framework built through the work
Ximple began with a backpack. Designing the Hero Backpack in public made trade-offs visible: what to add, what to remove, which constraints to accept and which features truly earned their place.
That discipline became a way of reviewing other backpacks — not as simply good or bad, but as systems of priorities, compromises and consequences. The same lens then moved beyond physical products into software, including reviews of Apple Notes, Things 3 and Notion, and into Ximple’s own apps.
Across those experiments, Dr. G. and Aime developed a shared framework for examining clarity, hierarchy, optionality, resilience and decision drift. What started as product design became a more general way of seeing.
That framework is now being applied through further Ximple collaborations — to books, investing, software and other complex systems where better decisions begin with a clearer lens.
