Intro

What is Deta Surf?

Deta Surf, also referred to as the surf browser or deta-surf, is an open-source, intelligent browser and notebook designed to integrate your internet browsing directly with your stream of thought. Powered by generative AI, it functions as a personal reference engine and study sidekick that helps you write, explore, and organize data across a growing personal library of PDFs, YouTube videos, files, and websites. Unlike traditional browsers, the deta surf browser runs on local data file formats on your machine and is AI-model agnostic, meaning you can run local LLMs or bring your own API key to ensure a completely private and radically personal research experience.
