App-specific activity: None by default; if you configure a remote embeddings endpoint, the text you choose to index is sent there to create embeddings.

Downloads

Choose your computer below to download the installer directly. Most Windows and Linux PCs use Intel / AMD. For Macs, check Apple menu → About This Mac: an Apple M-series chip means Apple silicon; an Intel processor means Intel.

Security warning: macOS and Windows may show an install prompt.

This app is not signed with a developer certificate. macOS may show an unidentified-developer or “damaged” alert; Windows may show SmartScreen. These prompts don’t establish whether the app is safe.
A “damaged” alert can be a false positive for an intact build, but may also mean the download is corrupt or altered. Download a fresh copy using the links above. If macOS still blocks the app and you trust the download, you can remove its quarantine flag using Terminal:
1. Drag the app into your Applications folder first.
2. Press Command + Space to open Spotlight, type “Terminal”, then press Return.
3. Copy and paste xattr -rd com.apple.quarantine into Terminal, then press the Space bar once. Don’t press Return yet.
4. Open Finder → Applications and drag this app into the Terminal window. This adds the app’s exact file path to the command.
5. Press Return to run the command, then open the app from Applications.
This removes the downloaded-app restriction for this app; it does not repair a corrupt download.
