Windrecorder

Windrecorder is an open-source personal memory search engine that continuously records on-screen activity in a highly optimized and storage-efficient format. It captures screen content locally and builds a searchable database using OCR and image understanding, allowing users to rewind and rediscover anything they have previously seen. The system indexes only meaningful visual changes, extracting text, browser data, and contextual information to improve search accuracy and reduce storage overhead. It includes a web-based interface where users can browse timelines, analyze activity, and perform semantic queries on recorded content. The tool emphasizes privacy by running entirely offline, ensuring that all captured data remains on the user’s device without external transmission. It also provides analytical insights such as activity summaries, word clouds, and timelines, making it useful for productivity tracking and recall.
