OpenSair is a Mac-native AI agent that keeps all processing on-device. Instead of routing data through external servers, it runs a persistent agent harness locally with 50+ built-in skills covering browser automation, Google Workspace (Docs, Sheets, Gmail, Calendar), task scheduling, a personal knowledge base, cross-session memory, and social media management. Because nothing leaves the machine, it suits anyone handling sensitive workflows — freelancers, researchers, or professionals who need automation without cloud exposure. The persistent memory means the agent retains context between sessions rather than starting fresh each time. The skill library is broad enough to handle most common productivity and content workflows without stitching together third-party integrations, and the absence of a subscription cloud layer means no ongoing data-sharing trade-offs.
