Ketryon has launched untitled cards, a free pin board for notes, photos and documents that works on any device. Built in two days, it lets people link ideas with labelled arrows and share boards for live editing.

Eskilstuna, Sodermanland County, Sweden, October 14, 2026 /MarketersMEDIA/ -- Ketryon, a product studio in Eskilstuna, Sweden, has launched untitled cards, a free pin board for notes, photos and documents that works on laptops, tablets and phones. Users place cards side by side, draw arrows between them and label each arrow with a word such as "then", "but" or "because", turning a loose pile of thoughts into a plan or a story.

Most visual boards are either heavy tools built for teams or simple apps that lose track of everything when the user switches device. untitled cards is calm enough to use alone, works properly on a phone and can be shared when the owner chooses. No account is needed to start; boards sync across devices once the user signs in.

Notes come in six colours, with a pen for circling what matters. Photos can be added one at a time or as a whole album, which lands as a scatter of polaroids. Documents sit on the board as cards with a full page behind them, and users can also drop in PDF, Word, Excel and PowerPoint files. Search looks through notes, captions, arrow labels and the text inside documents. On a phone, a board becomes a scrollable list, with arrows as a path to follow.

A built-in assistant, the frog, draws simple doodles on request, and one board can be published as a public page.

"I wanted a board that's calm to use on your own and still works on the bus, not a team tool you have to set up before you can think," said Kenny Tran, founder of Ketryon. "You can start without an account and bring other people in only when you want to. If you invite someone to edit, it's free for them."

The first code was written on October 9, and by the next day the app had sign-in, cloud sync, real-time shared boards and a paid plan.

The free plan includes unlimited boards, notes and documents and 2 GB of synced storage. untitled Plus costs 69 SEK a month or 549 SEK a year and adds live co-editing, comments, 50 GB of storage and a custom domain for published pages. Only the subscriber pays; everyone they invite edits for free. Synced boards are stored in the EU, the app carries no ads, and any board can be exported as a single file.

A web clipper and a command-line tool, with a connection for AI assistants, are in development. untitled cards is available now at https://untitled.cards.
