Drag and drop
From your browser, desktop or file manager. Whole folders too, and the junk (a .log, a .DS_Store) stays out.
v0.1.0 · free and open source
The free, open-source alternative to Eagle.
Grimorio collects, organizes and finds your images, videos, sounds, PDFs and 3D models. Native, fast and AI-free. Your library is a plain folder you can open without it.
Also for Linux (.tar.gz) and Windows (.exe) · all releases
Windows 10 or laterLinuxFree foreverAGPL-3.0
Everything in sight. Videos play when you hover them and the detail panel shows what matters about each item.
Organize without leaving the keyboard. Stars with a number key, several items at once with Ctrl and tags in bulk with Ctrl K.
Find it as fast as you can type it. Tag suggestions, filters and stars in a single search box.
Zoom down to the pixel. And an eyedropper that copies the color with one key.
3D models with their own viewer. Rotate them, switch views with the axes and check their size in millimeters.
01 Collect
Anything goes in. And shows up right away.
Drag from your browser, paste with Ctrl V or capture part of your screen. Grimorio copies the file into your library, makes its thumbnail and palette, and has it ready to search.
Paste with Ctrl V
A copied image, some files or a web address. Paste it on the grid and it's in.
Capture a region
Ctrl Shift X and draw around part of the screen. The capture goes straight into your library.
Watched folders
Pick a folder, like your downloads, and whatever lands in it gets imported on its own.
Bulk import
Thousands of files at once, with a progress bar and a window that never freezes.
No duplicate copies
If an identical file is already in your library, Grimorio spots it on import and you don't end up with three of the same.
02 Organize
Organize the way you think. With keyboard or mouse.
Tags, stars, notes and folders that combine without getting in each other's way. An image can live in several folders at once, and everything works the same with one item or a hundred.
Tags with groups and colors
Autocomplete as you type, groups to keep things tidy and a color for each group.
Stars
From 0 to 5 with the keyboard. Later, filter for the ones above four.
Notes
Write down why you saved something. Notes are searchable too.
Nested folders with colors
As many levels as you like, each with its own color. An item can live in several.
Smart folders
Save a search and it becomes a folder. It keeps itself up to date.
Batch rename
F2 with several items selected and a pattern like ref-{n:3}-{nombre}.
Undo anything
Every change can be undone, including the one that touched a thousand items at once.
A real trash
Whatever you delete goes to the trash. Nothing disappears until you empty it.
Safe mode
Mark sensitive items as 18+ and they get blurred in the grid. Handy when you share your screen.
03 Find
Find it as fast as you can type it.
One search box understands words, tags and filters. Type #warm estrellas:>=4 and you're there. Searches you run often can be saved as smart folders.
Search with suggestions
Tags and folders show up as you type, with how many items each one holds.
Filters that stack
Type, color, date added, stars, orientation and duplicates. They combine with each other and with what you type.
Search by color
Every image comes with its palette. Click a swatch and everything that shares it shows up.
Duplicates
Exact copies and near matches, even when the size changed. A hundred thousand checked in half a second.
Sort the grid
By date, name, size or stars, from the sort menu.
04 Browse
See everything without opening another app.
Double click or press Enter and the viewer opens instantly, tailored to what you're looking at. Press Esc and you're back where you were.
Pixel zoom and eyedropper
Get close enough to see the grid. Press C and the color under the cursor is copied.
Audio with waveform and spectrum
See how it sounds before you hit play. Click the waveform to jump to that moment.
Video with real controls
Speed, frame by frame with , and ., and an A-B loop.
PDF page by page
With a thumbnail in the grid and PgUp or PgDn to turn pages.
3D models
STL, OBJ, 3MF, glTF and more. Blender-style axes and a button to straighten the part.
Previews for PSD, RAW and friends
PSD, AI, EPS, Krita, Sketch and RAW files show up without opening the app that made them. Fonts are stored and organized too.
Night or paper
Two themes and an interface scale from 80 to 150%. Every visual detail comes from a JSON theme you can copy and tweak.
Performance
Fast with 100,000 references.
Every release is measured against a library of one hundred thousand items on an ordinary laptop. If something gets slower, that release doesn't ship.

Your data is yours
A folder you can read.
If you ever stop using Grimorio, your things stay right there, with their tags and notes, readable in any text editor.
Human readable

item.jsonper item next to the original file. Theindex.sqliteindex is derived, so you can delete it and it gets rebuilt.No webview
No Electron, no Tauri, no hidden browser. A native app that starts fast and uses little memory.
The core needs no window
Everything the app does can be done from the terminal with
grim. The interface is just one more client.No AI
No auto-tagging, and nothing that sends your images anywhere. What you save never leaves your computer.

Compared to Eagle
Side by side, honestly.
Eagle is a great app and the obvious inspiration. Grimorio is for people who want it on Linux, would rather not pay, or want their tools to be free software.

FAQ
Common questions.
Is it really free?
Yes. Free and open source under the AGPL-3.0 license. No account, no subscription and no “pro” version holding back the good parts. If an online service ever arrives, it will be optional and the app will stay complete.
Why is there no macOS version?
Because only what has been tested on a real Mac gets released. The core is portable, so it will come once it can be tested properly.
Windows warns me about an “unknown publisher”. Is it safe?
The installer isn't code-signed yet, and Windows SmartScreen warns about any unsigned program. Click “More info” and then “Run anyway”. The full source code is on GitHub for anyone who wants to review it.
Where are my files?
Inside your library folder, for example References.grimorio. When you import, Grimorio copies the file there next to an item.json with its tags, stars and notes. You can open that folder in your file manager whenever you like.
Can I sync it with Syncthing, Dropbox or Nextcloud?
Yes, because it's a plain folder. Just avoid opening it on two computers at the same time. If you like, you can leave out index.sqlite, which is a derived index and gets rebuilt with grim reindex.
On how many computers can I use it?
As many as you want. There's no license to activate and no device limit.
Does it use artificial intelligence?
No. It doesn't tag on its own, doesn't describe your images and doesn't send anything to any server. What you save never leaves your computer.
Can I bring over my Eagle library?
An importer for Eagle libraries is planned. Meanwhile, you can drag your image folders in and they keep their names.
Grimorio online · coming soon
Your boards, away from home too.
An optional service is in the works for what a desktop app can't do on its own. The app stays free and complete whether you use it or not.
- Share boards. Send a link and whoever opens it sees your selection, with nothing to install.
- Sync computers. The same library on your desktop and your laptop.
- Backups. A copy outside your home, just in case.
