Decide the first concrete outcome you want from it, so you can pick the right example, template or mode instead of exploring everything at once.
Clone the repository (or install the published package) and skim its README quick start for the requirements for your platform.
Run the documented install step and set any required configuration — such as provider keys, data sources or local services — before the first run.
Execute the smallest documented example end to end, confirm the output is what you expected, then adapt it to your real data or workflow.
Collect files and webpages into notebooks and work with them in one place.
Generate notes from a YouTube video, a PDF or other sources, and ask questions against them.
Notes can use a web-search tool when a question needs fresh information.
Generate small apps inside Surf with the app-generation tool.
A browser-like workspace with tabs and split view for research-heavy work.
Use local models or hosted ones — the project emphasises local, open data and user choice.
Get the source so you can inspect, configure and run it locally.
git clone https://github.com/deta/surf.git
cd surfDownload Surf from deta.surf or follow the installation guide in the repo for your platform.
git clone https://github.com/deta/surf.git
cd surf # see docs/INSTALL.md for the exact install/build stepsOpen a YouTube video or PDF and ask a question, or create a Surflet, as the README's TL;DR suggests.
# In Surf: visit a YouTube video and ask a question # see READMEIt is maintained by deta on GitHub (deta/surf), where the source, issues and releases live.
Yes — it is free and open source under Apache-2.0, which permits use, modification and commercial redistribution, with licence/notice retention.
You choose — Surf works with local models (no key) or hosted providers with your own API key.
Compared with Notion or Obsidian with AI plugins, surf's distinguishing focus is: deta Surf — personal AI notebooks that organise files and webpages and generate notes from them. Pick it when that focus matches your need; the alternative may suit you better if its broader or different scope is the priority.
Clone https://github.com/deta/surf (or install its published package), follow the README quick start to install and configure it, then run the smallest documented example — the Run section on this page mirrors those steps.
