   Retell AI

   Retell AI

   編集部のおすすめ

   ★★★★★

   –

   A pay-as-you-go platform for building AI phone agents: you set up the agent, number and integrations, and pay per minute for each part of the stack.

   長所

   • No platform fee or contract: start with $10 in free credits and pay per second of use
   • A dashboard builder with templates, plus an Auto Receptionist setup that starts from your website
   • Books into Cal.com, Calendly and GoHighLevel and syncs calls to HubSpot, Salesforce and other CRMs
   • Keep your existing number over SIP, or buy one for $2 a month
   • Self-serve HIPAA BAA at no extra fee, plus SOC 2 Type II
   • Agents can speak 55 languages, depending on the voice and speech-recognition providers chosen

   短所

   • You build and tune the agent yourself, or pay an implementation team or partner to do it
   • The per-minute price stacks several fees (platform, model, voice, telephony, add-ons), so the real cost depends on choices a business owner may not understand
   • Silence and hold time are billed, and numbers, SMS and extra concurrency cost extra each month
   • Retell's own pages disagree on details such as the free allowance (60 minutes or $10 in credit)

   Vapi

   Vapi

   ★★★★★

   $29/月

   A developer platform for voice AI agents: $0.05 a minute hosting plus the model, voice and transcription you pick, billed at cost.

   長所

   • Pick any model, voice and transcriber, billed at provider cost with no markup
   • A free US number and $5 in credits let you call a test agent within minutes
   • Dashboard templates for support and appointment scheduling, with Google Calendar and GoHighLevel booking tools
   • Blind and warm transfers, call recordings and an automatic summary after each call
   • Deep developer tooling: API, SDKs, CLI, config as code, simulations and monitoring

   短所

   • Built for developers: the receptionist logic, tools and providers are yours to configure
   • Costs stack from separate hosting, model, voice, transcription and telephony charges
   • The free number is US-only and inbound-only; outbound calls need a number from Twilio, Telnyx or another carrier
   • Texting needs your own Twilio account
   • HIPAA costs $2,000 a month extra

   Synthflow

   Synthflow

   ★★★★★

   –

   An enterprise voice AI platform for contact centers and multi-location brands, sold only as a custom annual contract with no per-minute rate or trial.

   長所

   • Synthflow's engineers can build and launch the agents for you
   • Connects to contact-center phone systems (Five9, RingCentral, 8x8, Zoom) and CRMs such as Salesforce and HubSpot
   • Keep your current carrier or phone system over SIP, or use your own Twilio account
   • HIPAA with a BAA, SOC 2 Type II, ISO 27001 and US or EU data hosting
   • Agents speak 30+ languages and can switch language mid-call

   短所

   • Enterprise only: an annual contract with no published price, no trial and no self-serve signup
   • Built for contact centers and multi-location brands rather than a single small business
   • Launch takes weeks, depending on integrations, phone system and security review
   • Choosing OpenAI models requires an Enterprise plan; Claude and custom models aren't supported

   My AI Front Desk

   AI Front Desk, Inc.

   ★★★★★

   $99/月

   An AI receptionist that answers, transfers and books calls, bundled with chat, SMS and a CRM, from $99 a month for 200 minutes.

   長所

   • Published price and overage: $99 a month for 200 minutes, then $0.25 a minute, with no contract
   • Self-serve signup with a 7-day free trial
   • Live-transfers urgent calls with a spoken summary and books into Google Calendar, Outlook or Calendly
   • Website chat, two-way SMS, email drafts and a CRM come in the same plan
   • Signs a BAA for HIPAA and connects to therapy, property-management and ecommerce software

   短所

   • Only 200 minutes on the self-serve plan; there is no larger published tier between it and custom Enterprise pricing
   • Outbound calls are capped at 20 a day on Business-in-a-Box
   • Keeps only the last 200 call and chat logs on Business-in-a-Box
   • Usage charges can apply during the free trial, and refunds are generally not given
   • API access is limited to custom Partner and Enterprise plans

   RingCentral AI Receptionist

   RingCentral

   ★★★★★

   $49/月

   RingCentral's AI receptionist (AIR) answers calls 24/7 on any phone system, books appointments and texts callers. From $49 a month for 100 minutes.

   長所

   • Works on top of any phone system by call forwarding or SIP, so you don't have to switch phone providers
   • Published pricing: $49 a month for 100 minutes, $0.50 per extra minute, and a 14-day free trial
   • Books appointments in Google, Outlook or Calendly calendars and logs leads to Salesforce, HubSpot or Zoho
   • Answers in six languages and switches language mid-call, with eight voices to choose from
   • HIPAA and SOC 2 compliant, and RingCentral says it doesn't train its AI on your data

   短所

   • Only 100 minutes are included; busier businesses pay $0.50 a minute past that
   • Getting RingCentral's own business phone adds $30 per user a month on top of the AI receptionist
   • Shopify and WhatsApp integrations are listed as coming soon, and the AI text agent may cost extra
   • The standalone plan is only sold in the US and Canada

   Goodcall

   Goodcall

   ★★★★★

   $79/月

   An AI phone agent you build by chatting with an assistant, billed per unique caller instead of per minute, from $79 a month for 100 callers.

   長所

   • Billed per unique caller, not per minute: long calls and callbacks from the same number that month cost nothing extra
   • Published prices from $79 a month, month to month, with no setup fee and a local number included
   • Set up and change the agent by telling Gabi in plain words, with practice calls and approval before anything goes live
   • Transfers to up to three people in turn, retrying busy lines
   • Books into Google Calendar and sends leads to Google Sheets, HighLevel or 10,000+ apps via Zapier

   短所

   • Answers in English only
   • Local US numbers only: no toll-free, Canadian or international numbers yet
   • You can't port your number in yourself; you forward your existing line instead
   • Your Goodcall number can send texts but can't receive replies yet
   • HIPAA use with a BAA needs the $299 Scale plan or Enterprise
