## Jelliu vs Synthflow

Synthflow is a no-code voice-agent builder focused on getting phone agents live quickly. Jelliu is also no-code, but it is built to run an entire operation: true omnichannel (voice, WhatsApp, email, web chat), an outbound campaign manager, a native CRM, and live conversion and sentiment analytics. If you want a voice agent fast, both work; if you want to run sales, support, scheduling, and collections across channels from one place, that is Jelliu’s core.

|  | Jelliu | Synthflow |
| --- | --- | --- |
| Build experience | No-code wizard | No-code builder |
| Channels | Voice, WhatsApp, email, web chat | Primarily voice |
| Outbound campaigns | Built-in dialer + campaign manager | Voice campaigns |
| CRM & contacts | Native CRM and contact lists | Integrations to external CRMs |
| Analytics | Real-time conversion + sentiment | Call analytics |
| Languages | EN, ES, PT-BR, FR, DE | Multiple |
| Best for | Running a full operation omnichannel | Standing up voice agents quickly |

### Where they overlap

Both Jelliu and Synthflow are no-code, so a non-technical user can build and launch an agent without engineering. If your need is simply a capable inbound or outbound voice agent, either platform will get you live quickly.

### Where Jelliu goes further

Jelliu treats voice as one channel in a single operation rather than the whole product. The same contact and conversation move across voice, WhatsApp, email, and web chat with shared context, so a missed call becomes a WhatsApp follow-up automatically.

It also folds in the parts a growing operation needs natively: a CRM and contact lists, an outbound campaign manager with pacing and retries, and live dashboards that score conversion and sentiment as work happens — not just per-call analytics.

### When to choose which

- Choose Synthflow if you mainly need to stand up voice agents quickly.
- Choose Jelliu if you need omnichannel, a built-in CRM, and campaign management in one platform.
- Choose Jelliu if you want one operating layer that scales from startup to BPO.
