A real 3D viewer
Rotate, zoom and measure every model right in the browser — no slicer round-trip just to remember what a file is.

Your 3D-print library, finally organized.
Point Trove at the folders you already have. It indexes every STL, 3MF and STEP in place — auto-tagged, instantly searchable, and ready to inspect in a real built-in 3D viewer. Nothing is moved, uploaded, or touched.

Built for makers
Three things every print library should do.
Trove is an original reimagining of the model manager — focused on the parts that actually slow you down: seeing what a file is, finding it again, and keeping it tidy without lifting a finger.
Smart auto-tagging
On scan, models are grouped into creators and collections and tagged automatically — so your library organizes itself.

Search that keeps up
A ⌘K command palette inside the app, plus a global Quick Find launcher that floats over everything to jump to any file in keystrokes.

Quick Find
One keystroke from anywhere on your desk.
Summon a Spotlight-style launcher over a frosted-glass backdrop and search your whole library by file name or folder. A live preview shows the model, its full on-disk path, and one-click actions.
- Type & jump. Prefix matches first, STL ahead of the rest — capped to what matters.
- Open in your slicer or reveal the folder in your file manager, straight from the preview.
- Copy the real path. Every result maps to an actual file on disk — no abstractions.

Your files, your rules
A window onto your collection — not another silo.
Most tools want to import, re-encode and lock your models inside their database. Trove does the opposite. Your folders stay exactly as they are; Trove just builds a fast, friendly index on top.
- Never moved or modified. Eject a library any time — your files don't even notice.
- Watches for changes. Drop a new STL in the folder and it appears, auto-tagged.
- Hands off to your tools. Trove finds & inspects — your slicer and file manager do the rest.

🍎 macOS first launch: Trove isn't notarized yet, so macOS may say it's “damaged.” It isn't — drag it to Applications, then run this in Terminal once:
