Everything here is a module of the operating system — the free tools let you feel the ideas in thirty seconds, and the paid ones are bound to your real tools and your real data. What you won't find: generic instruction packs, because a skill that doesn't know you is a costume.
The next paid tools are more connectors — and as they land, they bundle into multi-connector SKUs. The deepest version of all of it is the full engagement: apply for your operating system.
