Synthflow

No-code voice agents for phone ops: flows, numbers and minutes without a telephony team — Bland's more canvas-shaped cousin for CX that still lives on the PSTN.

Product preview

Overview

Synthflow is the canvas for people who want Bland's minutes without Bland's API: draw the flow, buy the number, let CX edit the script. Vapi is the platform; Retell is latency; Synthflow is the no-code door.

It will not beat a custom stack on barge-in. It will beat a six-month telephony project. Minutes are the bill. If the buyer is CX and the channel is still the phone, this is the default canvas.

Pros / Cons

Pros

CX can edit the flow without an API team
Numbers and minutes in one product

Minutes add up on real campaigns
Overlaps Bland and Vapi — pick a stack
