Isn't a vendor holding our prompts a real switching cost?

The arrangement is often presented as a competitive moat and does not survive examination. A genuine switching cost comes from something the incumbent holds that a rival structurally cannot obtain. Prompts written by the customer, describing the customer's own work, portable to any model, are not that. What holds the customer is where the material is stored.

Centralpoint removes the question by default. Skills and prompts are records in the organization's own SQL environment with version history, and the index is built and held locally. Nothing requires an ongoing relationship with Oxcyon for those assets to stay readable and usable, which is the only condition under which portability is more than a word in a datasheet.
