SurfSense

SurfSense is a private, open-source research notebook that runs entirely on your local machine, enabling users to work with confidential documents and generate outputs such as decks, reports, briefings, podcasts, and more without ever uploading data to the cloud. Users can choose or bring their own AI models—including local and OpenAI-compatible options—and use the tool fully offline after initial setup. It is designed for privacy-sensitive professionals like lawyers, consultants, and researchers who need absolute data control, as well as for general users who want a self-hosted, no-cloud AI productivity tool.
