A: Thanks, good questions.

Tiers: all three tiers unlock the same plan with the same features. The only thing that changes is how much you get each month: voice minutes, AI requests and storage. Tier 3 gives you 45 voice minutes, 1,000 AI requests and 10GB. Every tier includes unlimited seats, so you can bring your whole team in on one purchase. Buy Tier 1 now and upgrade later and it happens automatically, nothing is lost.

To be clear on your question, it's the same features as our Pro plan, just sized for a one off payment instead of a monthly one. And if you use up your voice minutes you can add your own OpenAI key and keep talking.

Data: your boards are stored encrypted and only people in your workspace can see them. We don't sell your data and we don't train anything on it.

The honest bit is that any AI feature means a third party sees what you're working with. Voice always runs on OpenAI, on every plan. Adding your own key just changes who gets billed, not where it goes. What they do with what they receive is covered by their terms rather than ours, same as when you connect your own AI assistant (MCP) to Tarsen. On our side we never record audio, just a text transcript that only you can read and that's deleted after 90 days. You can also turn AI off completely.

Export: yes, on every plan. JSON or CSV, one project or your whole workspace, any time you like.

Integrations: there's an MCP server, so you can connect Claude or a similar assistant to your board and have it read and update your cards. Right now things can come into Tarsen, but Tarsen doesn't push out to other apps yet. Good ask though, and it's one for the roadmap.

OpenRouter: not something we support today, but a good idea and I'll get it on the roadmap. Worth knowing voice would stay on OpenAI either way, since that runs on their realtime tech.
