Introduction

Synthflow AI agents talk to your customers and get things done on your schedule.

Agents can handle customer inquiries, schedule appointments, provide information and manage other interactions. Once you set them up, they can do all of this without any human intervention.

You can customise Synthflow AI Agents by providing specific data and instructions, enabling AI voice automation without coding or technical expertise.

Agents are particularly useful for customer support, and as an add-on to your existing workflows in many Integrated platforms.

The BELL framework

Synthflow organizes the entire agent lifecycle around the BELL loop—Build, Evaluate, Launch, and Learn. This is the operating system behind every polished experience we deliver: a repeatable rhythm that helps teams move from idea to world-class conversations without losing speed or quality.

Build

Design & Integrate Voice Agents

Shape the voice of your product, bring data together, and choreograph the perfect conversation. Design clear phone call journeys with a visual flow editor built for deterministic logic and branching—see how in the flow designer guide.

Evaluate

Simulate & Evaluate Voice Agents

Put every scenario through its paces before a single customer hears a word. Simulate lifelike calls, validate every branch, and evaluate against the success criteria that matter to your business with custom evaluation workflows.

Launch

Deploy & Scale Voice Agents

Ship with confidence and scale without surprises. Keep every rollout transparent with detailed call transcripts and safeguards, and wire Synthflow into your stack through the API / SDK with minimal lift.

Learn

Monitor & Improve Voice Agents

Let every conversation make the next one smarter. Spot opportunities directly in the flow designer, document the upgrades you want to explore next, and let analytics track performance, sentiment, and outcomes to fuel the next iteration.
