OpenAI memory is user-scoped and single-vendor: it remembers things for an end user inside ChatGPT. Oiya is organisation-wide, cross-vendor knowledge that any of your agents can use.
OpenAI memory gives a single assistant recall of past conversations. Oiya solves the multi-agent alignment problem, giving every agent in a company access to a shared, structured, governed knowledge layer that evolves with the business.
