Ship voice agents.
Pay by plan, not per minute.
PreCallAI is the developer-first platform for production voice bots. Connect your own provider keys, build with a clean API, and ship on a flat monthly plan — never a per-minute meter.

● agent connected — streaming transcript▋Connect the providers you already use — with your own keys
Everything you need to ship voice
A focused, voice-only platform built the way developers expect — API-first, transparent, and yours to control.
Bring your own keys
Connect your OpenAI, Deepgram, ElevenLabs and Twilio keys. You own the model spend and the relationship — we orchestrate the call.
Flat monthly pricing
No per-minute meter. Pick a plan by daily call volume and ship. Your bill is the same whether a call lasts 20 seconds or 20 minutes.
API-first by design
Create agents, place calls and stream events from a clean REST API. No SDK to install — everything in the dashboard is one HTTP request away.
Realtime events
Subscribe to transcripts, function calls and call lifecycle webhooks. Wire voice agents straight into your own backend.
Sub-second latency
Streaming STT → LLM → TTS pipeline tuned for natural turn-taking, barge-in and interruption handling out of the box.
Yours to control
Your keys, your data, your prompts. Export logs, rotate credentials and self-host on Enterprise. No lock-in.
Stop paying per minute
Every other voice platform meters you by the minute. We don't. Run the same workload and watch the difference.
90,000 metered minutes billed on top of model costs.
- Bill scales with every second of talk time
- Long calls punish you
- Unpredictable at scale
- Provider cost marked up
Flat Growth plan. Model usage runs on your own keys, at cost.

One REST endpoint. No SDK required.
Place a call with a single HTTP request and bring your own provider keys in the same payload. It's just HTTP — call it from any language.

Questions, answered
You connect your own provider accounts — OpenAI or Anthropic for the LLM, Deepgram for speech-to-text, ElevenLabs or Cartesia for voices, Twilio for telephony. PreCallAI orchestrates the realtime call; the model usage is billed by those providers directly to you. You stay in control of cost and data.
