Why it exists
I once tried to pass around a card on a friend's last day at work and hit a wall. Every usable service demanded an account, and the moment you ask twenty people in a group chat to “sign up and write”, half of them drop off. In the end I collected lines over chat and pasted them into a file, and I have no idea where that file is now.
A group card is decided less by the will of the person making it than by the hurdle in front of the people joining. So this service dropped sign-up, login and app installs from the start. Whoever gets the link can put up a sticky note without being asked anything.
How it was built
The first version began as a small experiment. As search traffic grew, it was rebuilt from scratch in the summer of 2026. The screens and features stayed the same, but the bugs where notes jumped or vanished when several people decorated at once were fixed, and drawing and image export were polished.
What is here now: canvas and list layouts, sticky note colors and ten fonts, photo and image stickers, pen and highlighter drawing (desktop), automatic syncing, and an image export that downloads the whole board as one PNG. The full walkthrough is in How it works.
Operating principles
- No sign-up, ever. A login for the organizer alone would be convenient in places, but the moment it exists, “one link” breaks.
- Free. No paid tier, no locked features. Server and domain costs are covered by ads shown on screen, placed only where they do not cover the writing and reading area.
- Minimal personal data. The only things collected are what you type: the card title, the messages, and the names attached to them. No email, phone number or real name is required. Details are in the Privacy Policy.
- The link is the permission. Anyone with the link can read and write. There is no password or invitation approval, but the address is a long random value that cannot be guessed, so nobody stumbles in without being given the link. For a surprise, you manage who gets it.
What happens to the data
Cards are not deleted automatically unless someone asks. But this is a free service run by one person, and permanent storage cannot be promised. That is why every page repeats the same line: save the finished card as an image. The PNG file lives on regardless of the service.
You can edit and delete your own sticky notes. To delete a whole card, send its address through Contact and it will be handled after verification.
Who runs it
One developer living in Korea builds and runs it. It is not a company, so there is no support desk and replies are not instant, but every email is read personally. Bug reports, annoyances, and “I wanted to use it for this situation too” are all welcome.
