Industries
Where latency, compliance, and containment are measured on every call.
Built to scale
Why teams replace IVR and basic IVAs with LLM-native agents.
Legacy
Touch-tone menus and fixed trees. Callers press 1, 2, 3 — no real dialogue, high abandonment.
Legacy
Intent mapping only. Weeks of configuration, brittle on unexpected inputs, mostly inbound-only.

FAQ
Everything prospects ask before their first live call.
An AI voice agent conducts natural phone conversations using speech recognition, large language models, and text-to-speech. It can book appointments, qualify leads, answer support questions, and trigger actions in your CRM — 24/7.
Legacy IVR uses rigid menus. Basic IVAs map intents only. CandexAI uses LLMs for open-ended dialogue, real-time tools, outbound calling, and sub-second latency — closer to a trained human agent.
Use the live demo on this page: enter your name, email, and phone, pick an agent, and receive a real outbound call in seconds. You can also talk to Sarah via the mic widget on any page.
Yes. Admins import numbers in the dashboard with Twilio SID and token. Outbound test calls and production flows use your configured default number.
We support 70+ languages with multilingual models. Agents can detect language mid-call and switch voices dynamically for global operations.
Production targets are ~600ms end-to-end for natural turn-taking. Actual latency depends on region, model choice, and telephony path.
Yes. Real-time function calling lets agents check calendars, update CRM records, process payments, and transfer to humans with context.
Yes. We offer private cloud and on-premise deployment so audio and inference stay in your environment. Public cloud demo uses encrypted transit only.
Yes. Upload recipient lists with dynamic variables (name, email, custom fields) and launch high-volume outbound campaigns with per-call analytics.
Prebuilt agents can go live in under two weeks. Custom flows with integrations typically take 4–8 weeks depending on compliance and CRM depth.
You receive transcripts, optional recordings, structured summaries, and dashboard metrics. Leads from the demo are emailed to your team automatically.
Absolutely. Define escalation triggers (sentiment, keywords, explicit request) and warm-transfer with full conversation history to your contact center.
