Two engines, one platform

The ecosystem

Plugs into your business. Talks to your customers.

Events come in from the tools you already run. waca decides what to say, says it on the right channel, and closes the loop.

1Events flow in: an order, a booking request, a new lead, a support ticket.

Connections are made through events your systems send to your workspace.

Why it matters

Customers don’t leave because of price. They leave because nobody answered.

Calls ring out. Chats wait.

Bookings and questions arrive at night and on Sundays. By the time someone replies, the customer has gone elsewhere.

waca →Answers every call and chat in seconds, any hour.

One language doesn’t fit India.

Customers think in Tamil, Hindi or Hinglish. A bot that only speaks English feels like a closed door.

waca →Speaks English and 22 Indian languages, on chat and calls.

Testing costs money.

Most tools bill every test message and call, while you’re still checking that the bot says the right thing.

waca →Rehearse every branch in a local test lab for ₹0.

Figures in these illustrations are examples.

The difference

Same call. Two endings.

A customer calls a clinic at 9:40 pm to book an appointment. Follow what happens with and without an AI calling agent.

Example scenario
  1. A patient calls to bookThe AI calling agent answers on the first ring.
  2. Slot found and booked“Thursday 10:30 am with Dr Rao works?” “Yes.” Done.
  3. WhatsApp confirmationDate, time, doctor and a map pin, in their language.
  4. Reminder the day beforeOne tap to confirm or reschedule.
  5. Patient arrivesYour desk never had to pick up the phone.

What makes waca different

Four things you won’t find together anywhere else.

Explore the platform →
01 · Visual journey builder

See the whole conversation before it happens.

Every automation is a flow you can read at a glance: what starts it, how long to wait, what to say, which channel to use, and where each reply leads.

Why it matters

No scripts hidden in settings. Anyone on your team can understand and change what the agent does.

  1. Pick a trigger: order, booking, appointment, lead, campaign or support.
  2. Drag in steps: wait, WhatsApp, call, branch, hand to a person.
  3. Branch on what the customer says, not just on buttons.

02 · One agent on calls and WhatsApp

Talks on the phone. Follows up on WhatsApp.

Your agent keeps one memory of the customer across both channels. What was said on a call shows up in the chat, and the other way round.

Why it matters

Customers never repeat themselves, and every call ends with something in writing.

  1. Connect your WhatsApp number and calling account.
  2. Choose a voice for each language.
  3. Mix call and WhatsApp steps freely in any journey.

1A customer calls to ask about a 2BHK.
03 · Speaks like India speaks

22 Indian languages, and everything in between.

Customers rarely stick to one language. waca understands mixed messages like Hinglish or Tanglish and replies in the same style, on chat and on calls.

Why it matters

People buy from businesses that sound like them. A reply in their language feels like a person, not a form.

  1. Turn on the languages your customers use.
  2. Pick a voice engine per language and listen in the lab.
  3. The agent follows the customer’s choice automatically.

04 · ₹0 test lab

Rehearse every conversation before you pay for one.

Play the customer in a private lab, on chat or a simulated call. Use scripted replies or a local language model, and see the reason behind every turn.

Why it matters

You launch knowing exactly how the agent behaves, without spending on a single test call or message.

  1. Type what a real customer might say, even the awkward bits.
  2. Read the trace: language, intent, policy, branch, tone.
  3. Fix, run again, and activate when it feels right.

Not every customer starts with “hello.” Turn on English and any of the 22 scheduled Indian languages, choose a voice for each, and hear it in the test lab first.

What it looks like in your business

Example scenarios
Today

Orders, questions and returns pile up.

COD parcels come back refused, “where is my order” fills the inbox, and festive campaigns get clicks but no conversations.

With waca

Confirm, support and sell on autopilot.

  • COD order → WhatsApp confirm → call if quiet
  • Order status and exchanges answered in chat
  • Campaigns that reply and send payment links
Outcome

Fewer returns, faster answers, more repeat sales.

Your team starts the day with confirmed orders and only the tricky support cases.

Questions

Good questions. Clear answers.

Is waca for calls or for WhatsApp?

Both. You can run a calling agent, WhatsApp automation, or journeys that mix the two. The same agent, knowledge and customer history work across both channels.

Can it sell, or only support?

Both. Agents qualify leads, recommend products, run campaigns and send payment links, and also answer questions, confirm orders, handle bookings and resolve support.

Can I test without making real calls?

Yes. The test lab rehearses chats and simulated calls with scripted replies or a local model, so you walk each branch before any telephony or cloud spend.

Can every business connect its own accounts?

Each workspace connects its own WhatsApp number and calling account. Conversations and customer lists stay inside that workspace.

What if a customer wants a real person?

You decide the handoff moments. When one is reached, your team gets the conversation with the full chat or call summary attached.

How do I get pricing?

Building and rehearsing is free. For live traffic, shape your plan and we’ll send a quote that fits.
