Deta Surf AI is an open-source, cross-platform intelligent multimedia notebook browser that blends a traditional browser, file manager, smart notebook, and AI assistant into a single local-first workspace, designed to boost users' ability to integrate and process information from multiple sources.
The product uses a 'local-first' architecture, storing all user data (such as notes, browsing history) by default on your local device, without relying on cloud servers, ensuring you have full control over your personal information and privacy.
It supports Web pages, PDFs, images, videos, screenshots, and other formats. Its AI features can summarize long videos, multi-page PDFs, content in foreign languages, and even scientific charts, perform text extraction (OCR), and offer in-depth analysis.
The core application is open-source and free, with most functionality running locally. The team plans to offer paid features in the future via optional cloud services (such as cloud sync), but local data storage and processing will remain free.
It's especially suitable for professionals such as students, researchers, developers, content creators, and product managers who need to efficiently manage and consolidate information from multiple sources, especially those who value workflow integration and data privacy.
Surflets are interactive mini applications (e.g., calculators, translators, charts) that you can create and embed without coding, allowing you to explore data and concepts dynamically and visually directly within your notes.
