Turnstone leans into a multi-agent workspace model, which can feel more like an operating system for work than a single assistant interface like OpenHuman. Instead of one “do everything” chat, it organizes specialized agents (for example, research, operations, or GTM) that collaborate over the same shared brain, making it easier to keep parallel threads moving without constantly reloading context.
A key reason to pick Turnstone is its bring-your-own-model posture: it’s designed to run on models you already pay for via your own API keys. That makes it compelling for teams and power users who want to swap models freely, control costs, and avoid being tied to a single vendor’s roadmap.
Turnstone also emphasizes a macOS-first, local knowledge base approach, with storage that stays on-device and connectors that can span both cloud apps and local folders. If OpenHuman’s “local-first assistant” idea resonates but the goal is more orchestration, more roles, and a more configurable operator setup, Turnstone is the stronger fit.
