How to choose ai voice agents & ivr tools
Most tools in this category fall into one of two camps. Some are complete contact centre or phone systems that now include AI agents. Others are platforms for building your own voice agents. Four things separate them:
- Build vs. buy. Vapi, Retell AI and Bland AI are aimed at teams that want to design and deploy their own phone agents through an API. Five9, Talkdesk and Aircall bundle AI agents into a wider contact centre or phone system, alongside human agents.
- Pricing model. Vapi, Retell AI and Bland AI are freemium. Aircall and Plivo offer free trials. Five9 is paid only, starting at $119/mo, and Talkdesk asks you to contact sales.
- API access. Aircall, Retell AI, Vapi, Bland AI and Plivo list an API. Five9 and Talkdesk are listed as web platforms only.
- Deployment and apps. Bland AI is the only listed tool with a self-hosted option. Aircall has apps for Windows, macOS, iOS and Android, which matters if people on your team also take calls. Plivo pairs its voice agents with carrier-grade telephony APIs.
Frequently asked questions
Are there free AI voice agent tools?
Vapi, Retell AI and Bland AI are freemium, so each has a free tier, with paid plans if you need more. Aircall and Plivo offer free trials rather than ongoing free plans.
How much do AI voice agents and IVR tools cost?
Among the tools listed, starting prices range from $29/mo for Vapi and $30/mo for Aircall up to $119/mo for Five9 and $299/mo for Bland AI's paid plans. Talkdesk pricing is available only by contacting sales. Retell AI and Plivo don't have a listed starting price.
What should I look for when choosing one?
First decide whether you want to build custom agents through an API (Vapi, Retell AI, Bland AI, Plivo) or buy a complete contact centre with AI built in (Five9, Talkdesk, Aircall). Then compare pricing models, whether you need a self-hosted option (only Bland AI lists one) and whether your team needs desktop and mobile apps (Aircall).
What are the alternatives to enterprise contact centre platforms like Five9 or Talkdesk?
For a lighter phone system with AI voice agents, there's Aircall. If you'd rather build your own agents, Vapi, Retell AI and Bland AI are developer platforms. Plivo combines voice AI agents with telephony APIs.
