AI agents from ₹1 a minute.¹
Speech recognition, the model and the voice, in one rupee rate. Billed in 10-second blocks, so short calls stay cheap.
The rate is in the contract
Here is how Synthflow and Frequency differ.
Synthflow is an enterprise voice-agent platform with its own telephony, warm transfers and a long compliance list. Its pricing page carries one figure: contracts start at $30,000 a year, and the per-minute rate is in the agreement. We publish ours. Pay as you go is ₹5 a minute with the phone line inside, and steady volume takes it to ₹1.
Synthflow is built for the enterprise buyer. Its pricing page has one plan, Enterprise, and one number: contracts start at $30,000 a year. The rate per minute, the concurrency and the telephony setup are scoped in the agreement. That’s a fine way to buy if you have a procurement team and a quarter to spend.
Most Indian teams calling customers don’t. They want to know what a minute costs before they talk to anyone, and they want to hear the agent in their own language today. So we put the rate on the page. Speech recognition, the model and the voice are ours, and they run on our own GPUs in India. On pay as you go the phone line is in the price too.
What a call costs on each
On Synthflow, $30,000 a year is where the conversation starts. At the ECB rate that is ₹28.49 lakh, before the rate per minute you agree on. Its docs count calls per second, pool the seconds across calls, and record an unanswered call as 5 seconds.
Ours is ₹5 a minute on pay as you go, line included. So 1,000 minutes cost ₹5,000. When your volume is steady, the volume plan takes it to ₹1 a minute. We bill in 10-second blocks, and if nobody picks up you pay nothing. The pricing guide shows how to forecast a month from your own call lengths.
