Surf

Surf, from Deta, is an intelligent notebook that brings files and web pages into a single note taking workspace. Instead of switching between a browser and a notes app, users collect websites, images, PDFs and other files into notebooks, ask questions about them and keep writing in the same place. Its AI features generate notes from media, summarize and explore YouTube videos, long PDFs, foreign language pages and scientific diagrams, and attach citations that link back to the source. Surflets let users create small interactive apps and graphs without writing code. The workspace also offers vertical tabs, sketching in notebooks, dark mode and drag and drop import of local files. Surf is built for researchers, students and anyone who gathers a lot of material from the web. It stores data locally on the user's device, with import and export under the user's control. The core source code is open on GitHub, and it works with the language model of the user's choice, including bring your own key or locally run models. The vendor describes the current release as an alpha moving to beta, with a rework for speed and stability under way. Pricing is not published on the site, which offers a download and a sign up for beta notifications.
