How pricing works

- Fonio AI (Hybrid) — Fonio AI is hybrid: a fixed subscription from $106/mo plus metered usage on top (Solo). Your real bill moves with volume, not seat count.
- PolyAI (Per Usage) — PolyAI bills purely on usage. There is no fixed per-seat fee, so the monthly cost depends entirely on how much you consume.
