PromptOwl provides a private AI context layer that persists knowledge across AI tools, ensuring that every session builds on previous work instead of starting from zero. The product consists of ContextNest Desktop, a free local context engine that indexes files into a persistent knowledge vault, and the PromptOwl governance platform that adds role-based access controls, approval workflows, audit trails, and agent orchestration for enterprise teams. It is designed for knowledge workers who want continuity across AI sessions and organizations that require governed AI access.
How It Works
- ContextNest Desktop runs on the user machine as a background process, indexing local files including Markdown, PDF, and other documents into a persistent knowledge vault that remains entirely on-device
- An MCP server connects this vault to any MCP-compatible AI tool including Claude, Cursor, and Antigravity, so they all draw from the same context without uploading files to the cloud
- The CLI provides init, verify, and publish commands for scripted workflows and CI/CD integration, giving power users programmatic control over their context vault
- PromptOwl extends ContextNest with governed vault access, role-based access control, approval workflows, and SHA-256 cryptographic audit trails for enterprise deployments
Key Capabilities
- Persistent context that retains knowledge across conversations and tools, eliminating the need to rebrief the model on each new session or when switching between AI assistants
- Local-first privacy architecture that keeps all files and indexes on the user machine with no cloud transmission or storage of user content
- Compounding knowledge that improves over time as more documents are added, with no session-level reset that loses accumulated context
- Multi-tool compatibility through a standard MCP server interface that works with Claude, Cursor, Antigravity, and any MCP-compatible client
- Enterprise governance layer with role-based access control, approval workflows, SHA-256 audit logs, and support for 125+ AI models under a single subscription
- Agent orchestration supporting simple, sequential, and supervisor agent patterns that operate on the stored context
- Integration with 8,000+ MCP tools and Zapier for automated workflow composition
