Deta Surf

Your knowledge is scattered across dozens of apps, files, and browser tabs — and pulling it together when you actually need it is a constant struggle. Deta Surf is an intelligent notebook that changes that by integrating PDFs, YouTube videos, websites, and photos into a single unified library. Powered by Generative AI, it helps you write, explore, plan, reflect, and think across your entire growing collection of information. It's open source, AI-model agnostic, and stores your data locally in open formats for full privacy and control. For students, it acts as a study sidekick, reference engine, personal tutor, and flashcard creator all in one — bringing your files and the web directly into your stream of thought.
