OpenYak – An open-source Cowork that runs any model and owns your filesystem

OpenYak is an open-source desktop AI assistant designed for complete local operation, offering professionals a private alternative to cloud-based AI tools. The application runs entirely on your machine, supporting over 100 AI models through OpenRouter—including Claude Opus 4.6, DeepSeek V3.2, and GPT-4.1—and allows users to bring their own API keys from 20+ providers like OpenAI, Anthropic, and Google. It emphasizes a 'local-first' architecture with no telemetry, ensuring all file operations, data analysis, and conversations remain on-device.

For workflow automation, OpenYak provides 20+ built-in tools and 7 specialized agent modes for tasks like batch file renaming, spreadsheet analysis, and document drafting. A key feature is OpenClaw integration, which lets the assistant receive and reply to messages across 8+ platforms including Slack, WhatsApp, and Discord from a single interface. The tool also supports long-term memory for context, MCP connectors for external services, and secure remote access via QR code, positioning it as a comprehensive, privacy-focused office automation suite.
