What’s a token?
Tokens meter the live transcription and the answers it drafts — the same way the underlying AI is billed. You top up from inside the app by bank transfer (scan a Techcombank QR code); tokens are added once we confirm the transfer. The balance is shown on the overlay and ticks down only as you use it. Heavier use costs more, but a typical question-and-answer is a tiny slice.
