Design multi-stage call flows visually — or describe them in plain English. No developers needed. Vapi, Bland, and Retell are API-only.
25 credits/min covers everything — AI models, voice synthesis, telephony, transcription. No separate LLM bills. No transfer surcharges.
Multi-stage conversation flows with tool gating, intent detection, and audit trails. Other platforms hand a prompt to an LLM and hope.
Real-time calendar booking with conflict detection, resource management, and multi-strategy scheduling. Most competitors require third-party integrations.
EU data residency, transparent AI disclosure (Article 50), encrypted data, full audit trails. No other voice AI platform offers native EU compliance.
Custom branding, sub-organizations, bring your own AI provider keys (9 supported). Perfect for agencies and resellers. SynthFlow charges $375+/mo for this.
Vapi advertises $0.05/min but that's just the platform fee — you pay separately for LLM, TTS, and STT, bringing real costs to $0.13–$0.31/min. Retell is similar. EolasFlow uses a credit-based model (25 credits/min) that includes everything — no surprise bills, no separate AI model charges.
SynthFlow Starter ($29/mo) includes only 50 minutes — about 2 calls per day. Their Pro plan jumps to $375/mo. EolasFlow's Team plan at €49/mo includes 5,000 credits, visual workflow builder, appointment booking, 50+ languages, and EU compliance that SynthFlow doesn't offer.
Bland AI is a developer API — no interface, no visual builder. You need engineers to build, maintain, and iterate. They also charge for failed calls ($0.015), transfers ($0.025/min), and SMS ($0.02 each). EolasFlow is ready in 10 minutes with no technical skills required.
Goodcall ($59–$199/mo) caps unique callers at 100–500 with limited language support. Smith.ai starts at $97.50/mo but only covers 30 calls — at $4/call, 100 calls costs $377. EolasFlow handles unlimited calls in 50+ languages with booking and CRM integration included.
EolasFlow runs a multi-stage orchestrator — not a single-prompt LLM. Each conversation stage has its own instructions, tools, and exit conditions. Tools are gated per stage (no accidental bookings during greeting). Full transition audit trail. MCP protocol for universal tool access. No other platform offers this level of control.
No. The VoiceFlow visual builder lets you design conversation flows by dragging stages onto a canvas. Or describe what you want in plain English and let AI generate the workflow. Platforms like Vapi, Bland AI, and Retell require developers.
