Tell it what you did. It keeps up.

A Kanban board you talk to. Say what moved. It moves.

Start freeTranscript of the Tarsen introduction. Hey. I am Tarsen. I am a Kanban board you talk to. Tell me what you did, and I move the card. Say a card is blocked, and I flag it and write the reason. No dragging. No forms. You talk. The board keeps up.

Free for one person. No credit card.

Underneath, a board you already know how to use.

A Tarsen project board: five lists from Inbox to Done, holding cards with labels, priorities and estimates, one of them two days overdue.

Tarsen Voice

Press ⌘J and say it. The board keeps up.

Keeping a board honest is a second job.

You finish the work, then go and tell the tool about it. Most people stop by Wednesday, and the board stops being true.

So say it instead. This is not dictation into a box. It is the assistant that runs the board, listening.

Ask

  • What am I working on?
  • What is blocked?
  • What did I miss?

Twenty-four things, out loud. It also labels, comments, ticks off checklists and archives. It only stops to ask before it deletes.

Free: 15 minutes to try. Pro: 30 each, every month.

A card keeps its number for life. TAR-133 is always TAR-133.

Mission Mode

Say how many hours you have. It picks the day.

It reads what is assigned to you: due dates, priority, what is stalled, what is blocked. Then it hands you the few cards that fit in the time you have left.

  • Every card tells you why it made the list.
  • It runs with no AI key, on the free plan.
  • It never moves anything without you.

Two cards are past their date and one of them is the Stripe duplication bug, so that goes first. The keyboard drag work is due tomorrow and mostly finished. The importer card is left out; it's still blocked on the Northwind export.

Works with your agents

Your assistant reads the board and changes it. No copying and pasting.

What is blocked on Roadmap, and who is it waiting on?

get_boardget_card

Two cards. TAR-128 is waiting on Priya, and TAR-141 is waiting on the client's copy.

create_card

Created TAR-147 in Roadmap, high priority, due Friday.

Make an API key, paste one line into your assistant, and it is talking to your real workspace. 14 tools cover projects, boards, cards and comments. 5 only read. 9 can change something.

  • It sees the projects you see, and nothing else.
  • A card it makes is a real card. Your team is notified.
  • Scope a key so an agent only touches its own work.
