💡 How Vowrite pricing works: Vowrite itself is free and open source. You bring your own API keys (BYOK) and pay providers directly for what you use. Mix and match — use one provider for STT and another for Polish.

📌 Notes: CNY prices converted at ~¥7.2 = $1 USD (July 2026). Prices sourced from official provider pages and may change — verify on the provider's billing page before high-volume usage. Monthly estimates assume ~15 hours STT + ~300K tokens Polish per month. Models marked ⭐ are the Vowrite default for that provider. Cells marked "—" indicate pricing not yet published or unverifiable at time of writing — check the provider's official page.
