Pensieve is a privacy-focused passive recording project that automatically records screen content, builds intelligent indexes, and provides a convenient web interface for retrieving historical data. Inspired by Rewind and Windows Recall, Pensieve differentiates itself by allowing users complete control over their data, avoiding transmission to untrusted data centers. Key advantages of Pensieve include easy installation, complete data control, support for full-text and vector searches, integration with Ollama, compatibility with any OpenAI API model, support for both Mac and Windows (with Linux support in development), and extensibility via plugins.
