A Kanban board that speaks Markdown.

Drag-and-drop boards where every card is real Markdown — with checklists, labels, comments and attachments, live-synced for everyone on the board, and open to your AI agent over MCP.

No sign-up, no card. Nothing you do in the demo is saved.

Try a theme:

Markdown-native

Every card description is real Markdown

Write in a WYSIWYG editor that produces actual Markdown — headings, links, task lists, code. One click on M↓ shows the source, and saves are explicit, with stale writes rejected rather than silently overwriting a teammate.

Bring your own agent

Your AI agent is a teammate, not an integration

Markboard speaks MCP, so 26 tools let your assistant read and write your boards — create cards in bulk, tick checklists, search, comment. Every write is attributed, logged in the activity feed and live for everyone watching. No destructive tools, by design.

How it works, and the full tool list

Real-time

Everyone sees the same board

Moves, edits, comments and checklist ticks stream to every open board over SSE — a couple of seconds, no reload. Hidden tabs drop their connection and re-sync when you come back.

Integrations

Your board, in the channel your team already lives in

Add to Slack or Discord in one click — authorize, pick a channel, and card moves, comments and checklist ticks land there. No URL to paste, no bot to configure. Anything else can subscribe too: point any endpoint at a board and get signed JSON, with retries and a delivery log. Pick from 34 event types per board, and payloads carry titles and who did what — never descriptions or email addresses.

Everything a board needs, nothing it doesn't

Labels, dates & checklists

Color labels, start/due dates with Overdue and Due Soon badges, and multiple checklists per card with live progress.

Attachments that preview

Markdown, text, PDFs and images up to 5 MB — PDFs open in a continuous-scroll viewer, images in their own photo viewer. Word docs download.

Search across everything

Match on title and description across every workspace you belong to, and land on the board with the card already open.

Filter without hiding

Filter by keyword, member, label, status or due date. Non-matching cards dim rather than disappear, so the board never rearranges under you.

Guests on a single board

Invite a client or contractor to exactly one board — no access to the rest of the workspace, and no way to invite anyone else.

Archive, not delete

Cards, columns and boards archive instead of vanishing, so the common destructive act is reversible. Permanent deletion is its own deliberate step.
