Questions
The things people ask before signing up, and the things they ask a week later. Straight answers, including where the product falls short. If yours is not here, email us and we will add it.
Talking to Tarsen
Do I need anything special to talk to it?
A browser and a microphone. There is no app to install and no headset to buy. Press ⌘J, allow the microphone once, and talk. A voice session is live, so it needs a connection.
What does it cost to talk?
Free gives you 15 minutes to hear how it works, once, rather than every month. Pro gives 30 minutes a month for each person, pooled across the workspace, and those reset on the 1st. Use them up and you can add your own OpenAI key in workspace settings to keep talking. Realtime audio is billed to us by the minute, which is why the number is a real allowance rather than a promise of unlimited talking.
What happens to what I say?
No audio is stored. The text of a conversation is kept for ninety days and then deleted, and only the person who spoke it can read it. There is no admin view of someone else's session. What everyone can see is the single sentence that caused a change, attached to the card it changed.
Can it delete something because it misheard me?
No. Deleting a card waits for a spoken yes, and so does creating a project. Tarsen reads the name back to you first and writes nothing until you agree. Voice can open your billing page or your member list, but it cannot change either one.
Can it see projects I cannot?
No. Voice acts as you. Every action it asks for is re-checked against your real permissions on the server, exactly as it would be if you had clicked the button yourself.
Plans and billing
Is there a free plan?
Yes, and it is not a trial that expires. It covers one person and as many projects as you like, with 10 MB per file and 500 MB of storage. It also includes 15 minutes of talking to Tarsen, once, so you can hear how it works.
What does Pro add?
People. Free is one person, and Pro is as many as you need. It also adds private and member-only projects, unlimited saved views, a year of Mission Mode history instead of a week, 100 MB per file and 25 GB of workspace storage. It turns on email notifications and gives each person 30 voice minutes a month, with the option to keep talking on your own OpenAI key. Projects are unlimited on both.
How is it priced?
Pro is £12 per person per month, or £120 per person per year. You pay for the people in your workspace, not for projects or boards. There is also Lifetime at £399, bought once and sized for a small team.
Is there a limit on workspaces?
No. You can have as many as you like on any plan: a work one, a personal one, one per client. Billing follows the people in each workspace, not the number of workspaces.
What happens if a payment fails?
Nothing abrupt. The workspace keeps working with a warning while the payment is retried. You are never locked out of your own work over an expired card.
What is the Lifetime plan?
One payment of £399 for the whole workspace, never billed again, with unlimited seats. It includes 300 AI requests a month, 2 GB of storage, unlimited projects, a year of Mission Mode history, and 15 minutes of voice each month on our key before your own OpenAI key takes over.
Your data
Can I get my data out?
Yes, on every plan, from Workspace → Integrations. A project or an entire workspace as JSON, which keeps the full structure and can be read back in; or your cards as CSV for a spreadsheet. Nothing is withheld or scrambled.
What if I stop paying?
A lapsed workspace falls back to the free plan’s limits and nothing is deleted. Export is not one of those limits. You can download your JSON or your CSV at any time, on any plan, before or after you cancel.
Where is it stored?
In Convex, which handles the database, live updates and file storage. Attachments are served through signed, expiring URLs rather than public links, so knowing a file’s id is not enough to read it.
Working day to day
Is there a mobile app?
Tarsen installs to your home screen as an app. On iOS use Share → Add to Home Screen; on Android your browser will offer it. It runs full screen and receives push notifications. There is no separate App Store download.
Does it work offline?
No. The board is a live connection, so everyone sees the same thing at the same moment. That is the trade: always current, but it needs a connection. Long text you are typing is saved locally as you go, so a dropped connection mid-paragraph does not lose it.
How do notifications reach me?
Three ways, each set per workspace: in the app, by push, and by email. A push only reaches a device you registered and allowed in the browser. Email needs Pro or Lifetime, and starts with invitations and mentions on and the rest off. There is no daily digest you did not ask for.
Can I use it entirely by keyboard?
Close to it. ⌘K opens the command palette, and cards, filters, priorities and navigation all have keys. Press ? anywhere to see the full list.
AI
Do I have to use the AI features?
No. Mission Mode ranks your day from due dates, priority, estimates, staleness and blocked state. That layer is deterministic and needs no model at all. A model only rewrites the explanation, and you can switch AI off for the whole workspace in settings.
Do I need my own OpenAI or Anthropic account?
No. The model is part of Tarsen and we pay for it, on every plan. Free allows 15 AI requests a day for the workspace, and Pro allows 100. Voice is the one place your own key comes in: on Pro and Lifetime, once the month's included minutes are used you can carry on with your own OpenAI key.
Can the assistant change my board?
Inside the app, no. It proposes, and you confirm before anything is written. If you connect your own assistant over MCP, it can create cards, edit them and comment, because you asked it to. Those actions are attributed to you and appear in the activity log like any other.
Can I connect my own Claude?
Yes, through the built-in MCP server. It takes about two minutes and the assistant then sees exactly the projects you can see, with your permissions.
Is my board used to train models?
No. Content is sent to a provider only when you use an AI feature, and only what that feature needs.
Teams and access
Who can see what?
Workspaces have owners, admins and members. A project can be open to the whole workspace, private, or limited to named people, and within a project someone can be a lead, an editor or a viewer. Every check runs on the server, not in the interface.
Can I stop members creating projects?
Yes, in workspace settings. Creation can be limited to admins.
Is there single sign-on?
Google sign-in is available. Enterprise SSO enforcement and directory provisioning are not built.
