Turnstone
Multiple specialized agents sharing one knowledge base make Turnstone a focused alternative to OpenHuman’s unified personal-assistant approach. Its chief-of-staff, research, and GTM agents are designed to work from the same accumulated business context. This structure suits workflows where different responsibilities depend on consistent knowledge of projects, preferences, and decisions.
Turnstone combines connected applications with local folders and lets users select which data contributes to its knowledge base. Bring-your-own-model access adds flexibility for users who want to choose their model providers rather than standardize on one service.
Scheduled workflows extend its appeal beyond on-demand conversations, particularly for recurring research or operational tasks. Turnstone is a compelling fit for macOS users who prioritize shared context and specialized agents, although API costs require separate attention and local knowledge storage does not necessarily mean local inference.
