Website and in-app chat that turns into a call in one tap.

Drop the widget on your site or use the SDKs in your web, iOS, Android, React Native or Flutter app. The same agent chats with rich layouts, recognises signed-in users, and moves to voice when it helps.

  • Website widget plus SDKs for web, iOS, Android, React Native and Flutter.
  • Cards, comparisons, bookable slots, checklists, carts, pay cards and multi-step forms.
  • Signed-in users recognised automatically; visitors verified with a one-time code.
  • Chat-to-voice and app call invites that carry the conversation's context.

What customers see on Web & app chat

  • Cards and side-by-side comparisons
  • Bookable time slots and ratings
  • Checklists, progress steps and key figures
  • Carts, pay cards and checkout
  • Multi-step forms and file upload
  • Galleries, tables, images, video and documents

One agent writes once; each channel shows the reply in its best native format, and anything a channel can't draw becomes clear text and links — so no choice or link is ever lost.

The Web & app chat problems Callaro solves

Website chatbots answer FAQs but can't finish anything.

The agent books, compares, takes payment and fills forms inside the chat — and calls your APIs to do it.

Frustrated users can't reach a human or a voice.

One tap turns the chat into a voice call with full context, or hands it to your team.

Signed-in users are asked to verify all over again.

Your app signs the user in once; the agent knows who they are on chat and in-app voice.

Anonymous visitors disappear when they leave the page.

A one-time code links them to a customer record, so memory and follow-ups continue on WhatsApp, SMS or email.

What the Web & app chat agent does

Guided selling layouts

Plan comparisons, product cards, galleries and tables help customers decide inside the chat.

Book, pay and apply

Bookable slots, carts with discounts, pay cards and multi-step forms complete the task in the conversation.

Knows who's chatting

Signed-in users are identified by your app; anonymous visitors can verify by one-time code so memory follows them.

Chat to voice

A tap starts a voice call in the browser or app that already knows the chat — no repeating, no re-verification.

Ring the app

Your team, your system or the AI can ring a customer's app instead of their phone.

Headless when you want it

Use the agent from your own interface and backend; replies arrive as signed events.

Not just text — cards, slots, carts and forms that get things done

The agent picks the best component for each answer from 29 rich message types. Customers compare, book, pay, upload and apply without leaving the conversation — and every tap goes straight back to the agent as a structured choice.

Chat and call, inside your own app

Drop Callaro into your website and mobile apps. The same SDK gives your users rich chat and in-app voice calls — and lets your team, your systems or the AI ring the app instead of the phone.

  • Rich chat with cards, slots, carts, forms and file upload — styled to your brand.
  • Tap to talk: an in-app voice call that already knows the chat and the signed-in user.
  • Ring the app: send a call invite that rings the user's app — accept to start a voice call; missed invites are recorded.
  • Signed-in users recognised with your own token — no second verification.
  • Push notifications so invites and replies reach users when the app is in the background.

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.

Live call · Real estate enquiry Live
  1. Hi, I'm calling about the 2BHK at Skyline Heights.
  2. Before the first word: CRM profile, last WhatsApp chat and open deal stage loaded into the agent's context.
  3. Welcome back, Priya — you asked about the east-facing units on WhatsApp yesterday. Two are still open.
  4. Tool call → inventory API: 2 units, live prices returned and used in the answer.
  5. Tool call → send WhatsApp: brochure, price sheet and site location delivered mid-call.
  6. Live event from your payment gateway: booking amount received.
  7. 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.

One customer, one memory — across channels

Web & app chat is one mouth of the same agent. Every message lands on the same customer record as their calls, chats and emails, so the conversation simply continues.

Chat → call

A stuck user taps to talk; the call starts with the chat's identity and history.

Chat → email or WhatsApp

"Email me the price list" — it lands in the customer's inbox or WhatsApp straight from the chat.

Anonymous → known

A visitor verifies once; from then on memory and live updates follow them on every channel.
