<h3>A powerful knowledge vault designed for ultimate control and flexibility.</h3><ul><li>Local Vault: Your notes are stored as plain Markdown files in a folder you own, ensuring complete data sovereignty. No background sync, cloud copies, or telemetry are involved.</li><li>Any Model Compatibility: Seamlessly integrates with any AI model you can access via an API key, including OpenAI, Anthropic (Claude), Google (Gemini), OpenRouter, xAI's Grok, and even models running locally like Ollama, LM Studio, and llama.cpp. Switching between models is a simple command.</li><li>Full Undo Capability: Every change made by an agent is meticulously logged. The `ferrow log revert ` command allows you to undo any specific change, and this revert action is itself recorded for a complete audit trail.</li><li>Agent Control: Agents can read and write to your vault under strict rules you define. Skills are defined as contracts with frontmatter specifying access permissions, ensuring that an agent cannot perform actions it hasn't been explicitly granted.</li><li>Secure and Private: Ferrow prioritizes your privacy. It does not ask for access to your Google or YouTube accounts. Any data transmitted is either to your chosen model provider or, if the relay is enabled, as sealed blobs that cannot be read by the relay itself.</li><li>Spend Control: Implement hard stops on AI spending with commands like `ferrow spendcap 5` to prevent unexpected costs.</li><li>Cross-Device Access: Use `ferrow hub start` to make your machine the central thinking hub, accessible from your phone and any browser through a secure relay.</li><li>Terminal and UI: Primarily a terminal-based application, Ferrow also offers a local browser UI (`ferrow ui`) for visualizing your vault and change logs.</li></ul>Ferrow is built on Node.js and offers easy installation via npm. It's designed for users who value data ownership, granular control over AI interactions, and a robust system for managing knowledge.
