The free tier is a real product — no time limit, no nag, no account.
Founding price ($39) is grandfathered permanently for early buyers before standard list price ($69) takes effect. One licence covers all platforms with perpetual offline verification. Education pricing: 40% off standard, institutional verification required.
Reassignable seats, one invoice, same one-time-and-perpetual terms as an individual licence — a team is a quantity, not a different product.
Reassign a seat any time. Because Tessamark verifies licences offline — so it keeps working with no internet and no login — a reclaimed seat stops working on the previous device at its next licence check, not instantly.
Version history and restore are free. Pro sells the presentation of that history, never access to it.

Yes. Tessamark runs no service, so there's nothing recurring to sell you. Major versions (v2+) are an optional upgrade at 50% of list.
Your prompts go to your provider on your credential. We never see them or bill you for them. Works with local models too.
Your files are plain markdown and your history is a standard git repository. Both outlive us.
Reassign it in the portal. It stops working on their old device at its next offline licence check, not instantly.
