Journal

Notes from the build.

The journal will publish engineering posts and founder essays as we ship. Until the first piece lands, here’s what we’re drafting.

Draft 01· In progress

The Studio is itself a Mind

Why we built the agent that interviews creators as a Mind in its own right — and what that taught us about asking experts the right questions.

Draft 02· In progress

Native citations in production

The implementation behind the inline citation chips: Anthropic’s structured citation_blocks, our boundary-snapping algorithm, and the verbatim-quote guarantee.

Draft 03· In progress

Per-subscriber isolation, by construction

A creator’s Mind is shared IP. A subscriber’s conversation is private. Here’s how we keep them separate at the database level.

Draft 04· In progress

Layered prompts, mandatory caching

Why every Mind’s system prompt is layered (identity · persona · expertise · skills) and why prompt caching isn’t optional in our cost model.

The first post lands when it’s ready. In the meantime, read how MindOS is built or start the conversation.
