Fluents versus Synthflow

Choosing an AI voice platform should be about results, not wrestling with setup, hidden limits, or complex pricing tiers. While Synthflow offers a polished no-code builder, businesses often face feature restrictions, plan requirements, and less flexibility when scaling.

Here’s our detailed comparison to help you decide which AI voice agent solution best fits your needs — from campaigns to compliance.

Fluents is built for massive outbound capacity.

Why are businesses switching to Fluents, and what sets it apart?

Campaigns Without Restrictions

Synthflow supports outbound calling, but advanced campaign types like lead reactivation or sales qualification are gated behind higher-tier plans. Fluents includes full campaign orchestration out of the box - no upgrade path needed.

Compliance You Don’t Have to Build

Do-Not-Call list management is built into Fluents and runs automatically. With Synthflow, there’s no native DNC support, meaning you’ll have to manage compliance manually or through external tools.

Enterprise-Level Voice AI, No Tiers Required

From sub-second latency to high-quality voices, warm transfers, and multilingual capability - Fluents delivers enterprise-grade features without forcing you into an enterprise plan.
