A team, not a bot

One agent per job.
Your entire call center.

Don't cram every call into one do-everything bot. Stand up a specialist agent for each department - each with its own knowledge, voice, and number - and callers reach the right one automatically. A full AI call center, assembled in a few clicks.

Billing agent

Handles invoices, payments, refunds, and plan changes - pulling balances and account details straight from your systems.

Tech support agent

Walks callers through troubleshooting from your docs, checks service status, and opens a ticket when it needs a specialist.

Sales agent

Qualifies new leads, answers pre-sale questions, and books demos straight onto the right rep's calendar.

Scheduling agent

Takes, confirms, and reschedules appointments, sends reminders, and keeps your no-show rate down.

Front-desk agent

Greets every caller, answers the routine, and routes the rest to the right department or person in seconds.

After-hours agent

Covers nights, weekends, and overflow so a real voice always picks up - taking messages that land in your inbox, with your team alerted by email or text.

How it works

Every call, handled
end to end.

A voice agent runs a full real-time loop on each call - hear, understand, decide, speak - in a fraction of a second.

1

Connects

A caller dials your number - or your agent dials out. The agent picks up instantly and greets them in their language.

2

Listens

Speech-to-text transcribes the caller in real time, so the agent understands naturally - interruptions and all.

3

Thinks

The language model reasons over your knowledge base and decides what to say or do - answer, look something up, or act.

4

Speaks & acts

A natural voice replies, the agent takes the action, and transfers to a teammate the moment it's needed - or takes a message when nobody can pick up.

Capabilities

Everything a great
phone team does.

Inbound & outbound

Answer every incoming call and run outbound campaigns - follow-ups, reminders, qualification - fully autonomously.

Works with your tools

Look up an order, check a booking, or update a record mid-call - call your own APIs directly, or reach 9,000+ apps through Zapier, Make, and n8n.

Numbers & routing

Assign phone numbers to a team and route callers to the right agent with simple rules. One agent or a whole department.

Grounded in your knowledge

Upload documents or scan your site. The agent answers from your real content - not guesses - and stays on policy.

Human transfer

When a person is needed, the agent connects the live call to a teammate - and if no one can take it, it takes a message instead.

Business-hours aware

Set your hours once. When you're closed, the agent stops offering transfers, tells callers when you reopen, and offers to take a message.

Takes messages, no dead ends

After hours or when a transfer isn't possible, the agent captures a name, number, and reason. Your team is alerted by email or text, and the request sits in one inbox until someone calls back.

Recordings & transcripts

Every call is logged with a recording, a full transcript, and the outcome - ready to review, coach, and improve.

HIPAA mode

One switch for sensitive lines: no recordings, transcripts, or call logs stored on the platform - reports still flow to your own systems.

Why it works

Trusted on
every call.

Accuracy you can count on

It answers like your
best employee would

Your agent speaks from your real information - hours, policies, prices, what's in stock - so every caller gets a correct, on-brand answer. No hallucinations, no going off-script.

  • Answers from your facts - grounded in your docs and site, never guesses.
  • Sounds human - warm, natural speech that replies the instant you stop talking.
  • Knows when to hand off - passes the caller to a person the moment it should.
