What it is
Deta Surf is an AI notebook that brings all your files and the web directly into your stream of thought. It runs on MacOS, Windows & Linux, stores data locally in open formats, and is open source. The project emphasizes local-first data, open data formats, open source, and openness with respect to AI models.
How it works
Surf uses a local storage engine named SFFS to store data in open and transparent formats. It provides a library of local files, sites & links, and supports media across multiple sources. Features include smart notes with @-mentions, web search triggers, deeplinked citations, Surflets for app generation, and the ability to paste in images or data for interpretation. The tool is designed to integrate with various AI models, with options to bring your own keys, add cloud models, or use local LLMs.
