Nerva Documentation
Build and integrate AI voice and chat agents with Nerva.
Welcome to the Nerva docs. Build phone agents, web chat agents, SMS, and WhatsApp bots powered by your prompts and your data.
Start here
- Getting started — sign up to first conversation in 10 minutes.
Agents
- Voice agents — phone agents on Twilio or Plivo with real-time STT/LLM/TTS, recording, and post-call analysis.
- Chat agents — web chat agents with rich messages, lead capture, knowledge base, and CRM tools.
- SMS agents — two-way SMS conversations with the same agent capabilities.
- WhatsApp agents — WhatsApp Business conversations, templates, and the 24-hour service window.
- Chatbot widget embedding — drop a
<script>on your site to embed a chat agent. - Phone numbers — buy, import, and assign numbers for voice and SMS agents.
- Knowledge bases — give your agent your menu, pricing, FAQs, and policies so it answers from your data instead of guessing.
- Agent tools — built-in tools, custom webhook tools, and MCP servers your agents can call mid-conversation.
- Campaigns — run outbound calling campaigns at scale with CSV upload, retry policy, and per-contact outcomes.
Integrations
- CRM integrations — connect GoHighLevel and more. Sync contacts, notes, tags, and pipeline stages.
- Webhooks — receive real-time events at any URL.
- Webhook events — full event reference with payload shapes.
- Verifying webhook signatures — HMAC verification samples in 6 languages.
Account
- Billing & plans — what counts as usage, plan limits, and how overages work.
