Introduction

As businesses increasingly turn to AI voice agents for lead qualification, 24/7 customer support, appointment booking, and outbound communications, evaluating the right solution is crucial.

What makes Spoki different from other WhatsApp platforms?

Spoki differentiates through its all-in-one approach: marketing automation, customer support, AI agents, Voice AI and 100+ native integrations in a single platform.

Does Spoki only work on WhatsApp?

No. WhatsApp is one of several channels. Spoki also runs Voice AI phone calls, SMS, email and RCS, and connects them in the same flow, for example a call that ends with a WhatsApp recap or an SMS reminder, with one conversation history per customer.

How does Spoki compare on pricing?

Spoki starts with a permanent Free plan (€0/month), then offers Service at €19/month and Marketing at €49/month. All plans include unlimited operators; most competitors charge per seat. Voice usage is billed per minute, roughly €0.05 to €0.30 depending on configuration, and Meta's WhatsApp conversation fees apply separately and are the same regardless of platform.

Can I switch to Spoki from another platform?

Yes. Spoki offers free migration support for businesses switching from other WhatsApp platforms. Your WhatsApp Business number can be transferred, and the Spoki team helps recreate your workflows, import contacts, and configure integrations. Most migrations complete within 48 hours.

What should I compare when choosing an AI voice agent or WhatsApp Business API platform?

Compare response latency, language coverage, voice and tone customisation, actions after the conversation (CRM sync, follow-up messages, human handover), call and chat records, EU data residency and GDPR terms, integrations, and the real total price per minute or conversation. Test each vendor with the same real scenario before you decide.
