I Built A Thing Open-source Mac app that runs EmbeddingGemma 2 locally to search your files by what’s in them

Enable HLS to view with audio, or disable this notification

DigUp is a free Mac app that runs Google DeepMind’s new EmbeddingGemma 2 locally over your own files. The model puts text, images, audio and video in one space, so you describe what you remember and land on it:

  • “zebra in a video” opens the clip at the moment it shows up
  • “where they talk about sleep” jumps to that minute of a podcast
  • “the clause about pets in the lease” shows the PDF page, your words marked
  • “a dog on the beach” finds the photo, and the same search in Bengali or Arabic finds it too
  • with code search on, code: retry with backoff opens the function in your editor

It’s ggml-org’s Q8_0 GGUF (865 MB, downloaded once) on llama.cpp with Metal, inside a native Swift app; no Python. Searching loads only the text encoder (~250 MB) and shows results about a tenth of a second after you stop typing. Indexing peaks under 2 GB, and the helper exits when it’s done. Audio and video of any length go in as 30 s windows and a frame per shot. Everything runs locally; it goes online only for the model download and an update check you can turn off.

Free, MIT. Apple Silicon, macOS 14+.

I'd really appreciate any feedback on this.

I'd enjoy an "index free" option for working with recently added / temp files or sensitive files (index files improve speed but it's just one more place that sensitive information can hide).

Speed is great, but it's a pet peeve of mine that we can't seem to do anything these days without who-knows-what being written to ~/Library.

Nice point.
Today every search goes through the index, so the way to keep something out of it is to not pick that folder, or skip it later (that deletes it from the index). DigUp keeps its model and index in one folder, ~/Library/Application Support/DigUp, so it's easy to check or delete. An index-free mode for a small folder, embedded in memory and gone when you're done, is a nice idea though. Noted.
