Why this model
We don't charge for tokens. We charge for what stays.
Per-token markup is what every other AI-coding tool has settled on. We don't, on principle.
The model is interchangeable; the intelligence you build on top of it isn't.
Free Tavsin already pays for itself: you avoid the markup, you keep your provider relationship,
and your project memory lives on your disk. The paid tiers exist for the things only money makes
possible — running agents in the cloud while you're away, syncing memory across machines,
and the one feature no individual workflow can build alone: a team's shared, compounding
intelligence layer.
