Dialzara vs Tone

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.

Tone is an open-source voice AI platform for building, deploying, and self-hosting voice agents. Agents can handle inbound or outbound calls, web widgets, or chat, combining prompts, tools, workflows, configurable models, voices, and speech-to-text providers. Its knowledge base accepts PDFs, scraped documents, Notion, and Confluence content, with chunking, embeddings, retrieval, re-ranking, citations, and custom vocabulary. A visual workflow builder supports branching, loops, human handoff, TypeScript hooks, and triggers from Zapier, REST API, or HighLevel. The test center runs simulated calls with personas, accents, and edge cases, supports parallel regression runs, and replays production calls. Observability includes interruption rate, latency, sentiment, gibberish detection, recordings, dashboards, and real-time alerts. Tone offers a TypeScript-first SDK, CLI, hosted API, and self-hosting through Docker Compose or a Kubernetes Helm chart. The Self-host plan is free. Cloud costs $0.09 per minute and includes $10 free credit with no card required; Enterprise pricing is custom.
