One agent, every channel, one memory.
Phone, in-app voice, website chat, WhatsApp, SMS, RCS, email and your own app via API — all live, all the same agent. A call can send the brochure on WhatsApp, a chat can turn into a call, and every channel knows what happened on the others.
Voice
Inbound, outbound and in-app voice that acts mid-call.
Catalogs, carts, checkout, flows and approved templates.
Web & app chat
Widget and mobile SDKs with rich cards and chat-to-voice.
SMS
Two-way texting with opt-outs and quiet hours built in.
RCS
Rich cards and carousels, with automatic SMS fallback.
Threaded replies from your domain and post-call recaps.
API channel
The same agent, headless, inside your own app or backend.
Single-channel bots break journeys. One agent completes them.
Customers call, then WhatsApp, then email. Separate bots forget everything in between. Callaro keeps one memory per customer and moves the conversation to wherever it finishes fastest.
| What happens when… | Single-channel voice or chat bot | Callaro omnichannel agent |
|---|---|---|
| The caller asks for the brochure | "We'll send it later" — often never | Sent on WhatsApp or email before the call ends |
| A chat user wants to talk | Start over with a phone number and a queue | One tap: a call that already knows the chat |
| A payment lands mid-conversation | Nobody on the call knows | The agent hears it and confirms it aloud |
| The customer replies on another channel tomorrow | A different bot with no history | Same agent, same memory, picks up where it left off |
| Your team needs to step in | Separate tools and lost context | One inbox, take over with a summary, hand back to AI |
| You want it inside your own app | A generic widget you can't restyle | SDKs for chat and calls, or a headless API for your own UI |
Tools, data and live events — inside the conversation, not after it
Most bots answer from a script and update your systems later. Callaro exchanges data with your systems while the customer is still talking — so nothing breaks when a journey crosses channels or something changes in real time.
Context in before the first word
Customer profile, CRM stage, open orders and the last conversation on any channel are loaded as the call or chat starts — the agent opens warm, never cold.
In-call tool calling
The agent calls your APIs, MCP servers and payment gateway mid-sentence — look up, book, update, charge — and uses the answer immediately.
Runtime context insertion
A payment, a CRM change or a chat message arrives while the call is live? It's inserted into the conversation within seconds, and the agent can say it aloud.
No broken hand-overs
Call to WhatsApp, chat to call, AI to human and back — each step carries the context forward, so customers never repeat themselves.
Engineered for speed
The agent is prepared before the call connects so the greeting is ready on the first moment of audio; prompts are cached, models chosen per use case, and turn-taking tuned for real phone lines.
- Hi, I'm calling about the 2BHK at Skyline Heights.
- Before the first word: CRM profile, last WhatsApp chat and open deal stage loaded into the agent's context.
- Welcome back, Priya — you asked about the east-facing units on WhatsApp yesterday. Two are still open.
- Tool call → inventory API: 2 units, live prices returned and used in the answer.
- Tool call → send WhatsApp: brochure, price sheet and site location delivered mid-call.
- Live event from your payment gateway: booking amount received.
- I can see your booking amount just came through — Unit 1204 is now reserved for you.
After the call: transcript, collected data and outcome to your CRM by webhook; open chats get a summary; a recap email lists what was sent.
Conversations that do things, not just say things.
Comparison cards, bookable slots, carts and checkout, checklists, carousels and forms — on website chat, in your app and on WhatsApp. Every tap goes back to the agent and moves the job forward.

Swipeable cards with images, prices from your data and buttons. The agent can't invent a price or link.

Choosing an AI agent? Check these first.
The questions that actually separate a production-grade agent from a demo. Callaro is built to pass every one.
Does it sound truly native to your customers — not just accented English?
77+ languages with native pronunciation packs (Arabic, Chinese, Indian & more), code-switching and locale-aware numbers.
Can you choose and change the AI models?
Pick STT, TTS and LLM per agent — swap them any time.
Is the cost transparent and controllable?
Exact per-minute cost by component, shown before you launch.
Does it actually take action, or just talk?
Tool calls, CRM writebacks, bookings and payment links mid-call.
Does it follow up and persist?
Automated retries, reschedules and multi-touch cadences.
Will it fit your telephony without rip-and-replace?
Bring Twilio, Plivo, Telnyx, Vonage, SignalWire or Amazon Connect.
