PreCallAI
PreCallAI is a developer-first platform for building production voice agents. You connect your own provider keys for LLMs, speech-to-text, text-to-speech, and telephony, then place calls and stream events through a REST API. The platform orchestrates the realtime STT, LLM, and TTS pipeline so you can ship voice bots without installing an SDK.
Unlike many voice platforms that bill per minute, PreCallAI charges flat monthly plans based on daily call volume. Model usage runs through your own provider accounts at cost, with no markup on OpenAI, Deepgram, ElevenLabs, Twilio, or other connected services. Plans cover orchestration, infrastructure, webhooks, transcripts, and analytics rather than metering talk time.
It fits teams building inbound support bots, outbound sales dialers, appointment booking flows, lead qualification, and after-hours receptionists. Healthcare, real estate, e-commerce, financial services, and other verticals have dedicated industry pages. Enterprise customers can get SSO, audit logs, SLAs, and VPC or on-prem deployment.

What does bring your own keys mean on PreCallAI?
You connect your own provider accounts for the LLM, speech-to-text, text-to-speech, and telephony. PreCallAI orchestrates the realtime call while model usage is billed directly by those providers to you.
How much does PreCallAI cost?
Starter is $9 per month for up to 100 calls per day. Growth is $29 per month for up to 5,000 calls per day. Enterprise offers unlimited calls on custom pricing. All plans require an active subscription, and model usage is billed separately by your own providers.
Do I need an SDK to use PreCallAI?
No. PreCallAI is API-first. You can create agents, place calls, and subscribe to events with standard HTTP requests from any language.
Can I use PreCallAI in production?
Yes. The Growth plan targets production voice agents with higher concurrency, call analytics, searchable logs, custom voices, and priority email support. Enterprise adds dedicated infrastructure, SLAs, and compliance controls.
What counts as a call on PreCallAI?
PreCallAI plans are sized by calls per day rather than minutes per call. The same flat plan price applies whether a call lasts 20 seconds or 20 minutes.
