Four endpoints - /teach, /guide, /practice, /assess. One identity provider, VOSE ID, that makes a learner's profile portable across every tutor in the ecosystem - same OAuth pattern as Sign in with Google, except what travels with the identity is the mastery map, the misconceptions, the proficiency curve. Every response carries citation chunks; every grade is reproducible from the corpus it stood on; every interaction compounds into a record the learner owns rather than the platform.
That's VOSE. Not a product. Not a platform. A contract surface any team can build a tutor on top of, and an identity layer that lets the tutors compound into something larger than any one of them could be alone.
Not a UI.We don't render anything. The learner-facing surface is yours.
Not a content library.We don't ship curricula or worked examples. You bring your corpus; we orchestrate retrieval against it.
Not an LLM.We don't train or host frontier models. We're the layer between the model and the learner that has been missing.
Not a tutoring app.That's Verdict's job, and Pallo's, and Khanmigo's. We make those products faster to build - not redundant.
One identity. A hundred tutors. Open chunks underneath them all.
That's the bet. That's the layer worth building. That's why VOSE exists, and why we're not building it as a product.
