Kaartje Demo · 2 min
Press a key, get a Trello card with the page, mail or file you're looking at already in it.
That's the whole app. Recorded on my own Mac, no cuts, sound on.

Sulejmanmade this, Netherlands
I use Trello for everything, and getting stuff into it was always the annoying part: switch to Trello, find the board, new card, paste the link, switch back. Trello's own desktop app has a quick add window, but it only takes a title and you still type everything yourself. So I built the version I wanted.
Kaartje is Dutch for "little card".
First 50 · free for good
Not for sale yet. Want to test it?
I'm finishing notarization and licences. The first 50 people who email me get a free licence, for good, in exchange for honest feedback, especially about which apps the autofill should support that it doesn't yet.

Autofill
Starts filled in
Press ⌃⌥Space in any app (change it if you like). The card comes up with:
- Safari, Chrome, Arc, Brave, Helium and other Chromium browsers: tab title and URL
- Mail: subject, sender, and a link that reopens the message
- Finder: the files you selected, as attachments
- Any app: the text you selected becomes the title
This is the panel
The grey chip is the link it captured; click × if you don't want it on the card. The labels are your board's own labels.
Screenshots
Screenshot, paste, drop
⌘⇧S hides the panel, you pick an area or a window, and it lands on the card. ⌘V an image, or drop files onto the panel.
Boards & labels
Your boards, your labels
Pick board and list in the panel. Set a default. Kaartje remembers the labels you used last time on each board.
Keyboard
Out of the way
Menu bar only, no Dock icon. Return saves, Esc cancels, and you're back where you were.
What it doesn't do 3
By design
No due dates, checklists or members
It's for getting things onto a board fast, not for managing the board. Trello is good at that part.
No Windows, no iPhone
Mac only, macOS 14 or later. Apple silicon and Intel.
Firefox: selected text only
Firefox doesn't tell other apps which tab is open, so there you get the text you selected and nothing else.
The boring facts 3
Swift, not Electron
About 4 MB. Starts instantly, sits in the menu bar, uses next to nothing.
Privacy
Talks to Trello and nothing else
No account, no server, no analytics. Your Trello token lives in the macOS Keychain. The long version.
Three permissions, all optional
macOS asks for Automation (to read the current tab or message), Accessibility (only for selected text) and Screen Recording (only for screenshots). Say no to any of them and the rest still works.

Questions 5
Do I need the Trello desktop app?
No. Kaartje talks to Trello directly. You sign in with your Trello account once.
Where do the link, screenshot and labels end up?
The link goes at the bottom of the card description, so it's clickable in Trello. Screenshots and files become attachments. Labels are your board's existing labels; nothing new is created.
Can I change the shortcut?
Yes, in Settings. Anything you like.
Does it work with free Trello?
Yes. Attachments follow Trello's limits: 10 MB per file on free workspaces.
Guide
How does it compare to Trello's own Quick Add, the bookmarklet, email-to-board?
I wrote up all six ways to add a card from a Mac, with what each one fills in for you. Read the guide.
