Frequently Asked Questions about Deta Surf

Can I use Deta Surf with my own LLM API key, or do I have to use a specific model?

You can bring your own LLM or run local models instead. This flexibility means you control which AI service powers your analysis, whether that is OpenAI, Anthropic, a self-hosted model, or another provider. You are not locked into a single vendor.

Does Deta Surf store my notebooks and files on its servers, or locally on my device?

Data stays local on your device by default, which means your research, notes, and imported files are not sent to Deta's servers. This setup gives you privacy control, though you should verify the current storage behavior on their site since the product is still in beta.

Can I summarize YouTube videos and PDFs directly in my notebook, or do I have to download them first?

You can analyze YouTube videos, PDFs, and web pages directly within your notebook without downloading them separately. The AI will summarize and extract information from these sources and pull the results into your notes alongside auto-generated citations.

What file types can I drag and drop into Deta Surf?

PDFs, images, and documents can be imported via drag-and-drop. The platform also analyzes web pages and YouTube videos without requiring a file upload, so your ability to work with content depends on the source format rather than a strict list of supported file extensions.
