Platform

Everything between “hello” and the follow-up.

One agent platform, four channels

Build an agent once and put it to work wherever your customers already are — on the phone, on your website, on WhatsApp, or over SMS.

—Inbound and outbound voice over Twilio or Plivo numbers
—Web chat widget you embed with a script tag
—WhatsApp and SMS conversations with session history

Outbound calling campaigns

Upload contacts, pick an agent, and let campaigns dial through your list with concurrency controls, retries, and per-contact outcomes.

—Contact lists with per-contact variables
—Concurrency and pacing controls
—Call outcomes written back to every contact

Workflows and agent swarms

Design conversation logic visually. Route between steps, call your systems mid-conversation, and hand off between specialized agents.

—Visual builder with nine node types
—Webhook tool calls into your own APIs
—Multi-agent handoff for specialized tasks

Knowledge your agents actually use

Feed agents your documents and websites. Content is chunked, embedded, and retrieved mid-conversation so answers come from your source of truth.

—PDF, Word, CSV, and URL ingestion
—Automatic re-crawl keeps web sources fresh
—Retrieval grounded in your own content

Every call, understood

Recordings, transcripts, and an LLM analysis of every conversation — outcome, sentiment, and follow-ups — rolled up into org-wide analytics.

—Full transcripts with recordings
—Automatic post-call analysis
—Per-call cost tracking and usage analytics

For developers

API-first, dashboard optional.

Everything you can click in the dashboard you can call over HTTPS. Place calls, manage agents, and receive events from your own stack.

—REST API for agents, calls, and campaigns
—Org-scoped API keys with granular scopes
—Signed webhooks for call and chat events
