I design AI-native products and coach teams on how to work alongside AI. The more I worked that way, the more I felt the same friction: every new chat window started from zero. The context I had accumulated — decisions, patterns, reasoning, preferences — lived nowhere a model could actually reach it.

Sentiuma is my answer to that problem. A portable memory layer built on plain markdown, queryable by any AI, owned entirely by you. No vendor lock-in. No proprietary format. Just your knowledge, made legible to models.

The thinking behind it — knowledge architecture, AI-native workflows, portable memory systems — is documented at rsimms.com. That is the home base. Sentiuma is the tool that came out of living those ideas.
