Notes on an infinite canvas, linked by lines, arrows and dashes.
jkboard is a free, minimal note board: drop notes anywhere, connect them with lines, arrows or dashed links, move, colour and search them — and keep everything in one open .jk file.
Simple by design. No account and no setup screen: open the board and start writing. Notes stay readable at any zoom, from 5 % to 800 %.
Select anything, change everything at once. Select several notes — or several connections — with Shift or a drag rectangle, then one tool changes the style of all of them.
Open .jk format. Boards are saved as plain XML that any text editor or AI assistant (Claude, ChatGPT…) can read and write — ask your favourite AI to build you a board and import it.
Your language, your theme. English, French, Spanish, German, Portuguese, Italian, Chinese and Hindi; dark, light or automatic theme.
Free to use. Premium mode shows no ads; Basic mode shows an ad space that helps keep jkboard free.
