For most of financial history, holding value meant trusting an institution to hold it for you. The institution was the product. Then a technology arrived that made individual custody practical, and a generation reorganized its relationship to ownership around a single sentence. Your keys, your coins. That sentence carries a complete worldview. It says that possession beats permission. It says that a promise to safeguard something is weaker than the ability to hold it. It says the person who controls the key controls the asset, and everyone else is a guest. The same worldview applies, unchanged, to intelligence. *** #### What is at stake A conversation with a model accumulates. Over months, a workspace learns how a person writes, what they are building, who they work with, what they are worried about, and where their judgment is weak. That accumulated record is the most revealing asset most people will ever generate, and today it is generated directly into someone else's custody. The question is who holds it. *** #### The position YveChat occupies one word. **Sovereignty.** Sovereignty means the keys sit on your machine. It means the data lands on infrastructure you provisioned. It means your identity is a signature you produce and control. It means that when a model runs locally, the conversation reaches no provider at all. Every design decision in this document resolves toward that word. Where a choice makes the product easier and the user less sovereign, the sovereign path wins, and the cost of that choice is stated plainly in [Limitations](/wp/product-scope/limitations.md). *** #### The audience This document speaks to people who already hold their own keys. Operators, builders, researchers, and privacy maximalists who run their own infrastructure and treat custody as a default. They arrive with the belief already formed. They need the belief extended into a category where they have never applied it. That focus is deliberate. A workspace built for everyone would trade custody for convenience at every decision point, and arrive somewhere unremarkable. *** Money proved the thesis. Intelligence is the second application. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://yvechat.gitbook.io/wp/proposition.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
