The platform

One workspace. Every conversation.

AI calling agents and WhatsApp automation that sell and support: orders, bookings, appointments, campaigns, leads and service. Here’s how the pieces fit together.

How waca works, end to end

Agents

An agent that sounds like your best person.

Give your agent a name, a personality, the languages it speaks and the knowledge your team already has. It answers within those lines and knows when to stop.

  1. Name and tone: warm, patient, never pushy.
  2. Knowledge: return policy, delivery zones, catalogue, timings.
  3. Boundaries: topics to avoid and when to hand over.

Calling agent + WhatsApp

One agent, two channels, one memory.

Chat is quick and cheap; a call is personal and hard to ignore. waca uses both in the same journey, and the agent remembers everything across them.

WhatsApp

Reminders, confirmations, two-way support, quick-reply buttons.

Voice calls

Inbound and outbound, a voice per language, comfortable with Hinglish.

Hi Ravi! Please confirm your COD order of ₹1,890 for tomorrow.

Languages

English plus all 22 scheduled Indian languages.

Turn on what your customers use, pick a voice for each one, and listen in the test lab before going live.

Test lab

Practise before you pay. Every branch, ₹0.

Play the customer in a private lab. Use scripted replies to walk each branch, or a local language model to improvise like a real person would.

  1. Scripted mode checks that every branch fires.
  2. Local-model mode tests the awkward, real-world answers.
  3. Every turn shows language, intent, policy, branch and tone.
Why it matters

Nothing touches telephony or cloud models until you press Activate.

Human handoff

Knows when to step aside.

You decide the moments a person should take over: an upset customer, a large refund, a custom request. Your team receives the conversation with everything attached.

Why it matters

Automation handles the routine. Your people handle the moments that matter, without asking the customer to start over.

The sofa arrived damaged. I want a full refund of ₹18,500.
Refund over ₹5,000→ HANDOFF
I’m really sorry about that. I’m passing this to Neha from our team right now, she’ll message you within the hour.
