Dialzara vs Retell AI

Dialzara is a web-based AI receptionist and website chatbot service for businesses. Its receptionist provides 24/7 answering with custom scripts and can handle English and Spanish when enabled. It checks live calendar availability for appointments, routes calls by topic, caller type, or priority, and supports time-based routing with an after-hours message fallback. Spam controls include threat detection, silence timeouts, retry prompts, and manual block and allow lists. Call summaries can arrive by SMS or email and may include voicemail audio and transcript links. The website chatbot answers questions, qualifies leads, and books appointments using the receptionist's shared knowledge base. It installs with one JavaScript line on WordPress, Shopify, Webflow, Squarespace, or custom sites, and supports automatic language detection with replies in more than 10 languages. Dialzara also lists CRM updates, Zapier workflows, and HIPAA compliance for healthcare businesses. Business Lite costs $29 a month, billed monthly, for 60 minutes, with a $0.48/minute overage. A 7-day trial is listed; there is no free plan.

Retell AI is a platform for building, deploying and managing AI agents that handle phone calls. Agents can also work through web and in-app chat, SMS and custom API-based communication. A visual canvas supports call flows with functions, integrations, transfers, DTMF, SMS and custom logic. Teams can simulate scenarios, turn production calls into regression tests and QA calls. Deployment options include inbound calls, outbound campaigns, web and SMS, including a website widget. Call handling includes IVR navigation, live monitoring and transfer or takeover by a person. The integrations directory names Twilio, GoHighLevel, HubSpot, Salesforce, Zapier, Make, n8n and Google Workspace. The homepage lists HIPAA, SOC 2 Type II, GDPR and ISO 27001 compliance, along with SSO, personal information redaction and module-level role permissions. Enterprise on-premise deployment is available within a customer’s infrastructure.
