The building blocks
Agents
Configure voice, model, prompts, abilities, and channels. Publish a version and go live.
Knowledge Bases
Upload documents and crawl URLs. Agents retrieve the right snippets to answer accurately.
Workflows
Visual automation. Triggered by events, calls, or schedules. Calls APIs, runs code, branches on AI.
Channels and reach
Channels
One agent, many channels: phone, web voice and chat, and email.
Phone numbers
Buy numbers, route inbound calls, and bring your own carrier.
Web widgets
Embed an agent as a chat and voice bubble on your site.
Verify a domain and let an agent answer real email.
Campaigns
Dial lists of contacts on a schedule, at scale.
Conversations
One inbox for every interaction, with transcripts and recordings.
How they fit together
A typical setup looks like this:- You create an agent with a voice, an LLM, and a system prompt that defines its persona and goals.
- You deploy it to a channel — a phone number, a web widget, or an email address.
- You attach a knowledge base so it can answer factual questions from your documents.
- You expose workflows to the agent as tools, so it can take actions mid-conversation (look up a CRM record, schedule a meeting) or run automations after a conversation ends.
- You review every interaction in Conversations, and run outbound at scale with campaigns.
