Can I use Deep Search on my phone?

Deep Search is designed for desktop computers, where it can leverage powerful hardware to run AI indexing and deliver accurate results. It is currently available for macOS and Windows.

Do I need a Synology device to use Deep Search?

Deep Search is standalone desktop software and does not require a NAS, BeeStation, or other Synology hardware.

Does Deep Search require an internet connection?

Deep Search runs entirely on your computer. Your files remain on your computer at all times and are never uploaded to Synology or any cloud service.

Core indexing and search are performed locally and work offline. Optional features such as photo location recognition or cross language processing may reference operating system level services or public reference data. These features do not access or transmit your file content and can be disabled in settings.

What can Deep Search index?

Deep Search indexes the folders you select from your computer and any connected external drives.
You stay in control by choosing exactly which folders to include or exclude at any time.

What file types does Deep Search support?

Deep Search works with many common image and document formats, including jpg, png, heic, gif, bmp, tif, and raw images, as well as pdf, docx, pptx, xlsx, csv, and txt documents.

What languages does Deep Search support?

Deep Search currently supports 12 languages including Dutch, English, French, German, Italian, Japanese, Korean, Polish, Russian, Spanish, Simplified Chinese, and Traditional Chinese.

How long will indexing take?

Indexing time depends on the number and size of files, as well as your computer’s hardware performance.

On an M3 MacBook, Deep Search can index about 30,000 to 40,000 photos per day or around 100 documents in 20 to 30 minutes, depending on file size and content. Large PDFs with hundreds of pages take longer. Small updates usually finish within minutes.

Optional features like photo location search and cross-language search may use external databases or macOS translation services, both of which can be turned off.
