Changelog

We’ve released OpenAI’s latest flagship model, GPT-5.1.

It significantly outpaces its predecessor (GPT-5) in speed and responsiveness, making real‐time conversational experiences much smoother. It is best suited for agentic tasks carried out by AI Agents.

Give it a try today and let us know your feedback.

We’re excited to announce that your AI Agents can now chat directly with users on WhatsApp! 🎉

With this integration, your agents can instantly respond to customer messages on WhatsApp, helping you generate leads, provide support, and engage users in real time.

💬 What this means for you

• Seamlessly connect your AI Agent to WhatsApp Business

• Manage all conversations from your Chatling dashboard

• Reach customers where they already are — no extra setup required

⚙️ How to set it up

Go to your agent’s dashboard → click Deploy in the sidebar → then click Setup under the WhatsApp integration option.

Start chatting with your customers on WhatsApp today and share your feedback with us! 🚀

Your AI Agents just got even smarter — and more multilingual.

You can now add translations for your Agent’s Initial Messages — the messages that appear at the start of a conversation.

Here’s how it works:

• Add translations for as many languages as you like.

• When a user starts chatting, your Agent automatically shows the Initial Message in their language — unless the widget language is manually set to a specific language instead of “Auto”.

• If no translation is available, it gracefully falls back to the default message.

This update makes it easier than ever to create personalized, language-aware experiences for your users right from the first interaction.

👉 Available now in your Chatling dashboard under Appearance → Texts → Initial Messages.

We’ve just made AI Agents even more powerful.

You can now add two brand-new actions to your Agents:

✉️ Send Email

Enable your Agent to send personalized emails automatically during a conversation — whether it’s a follow-up message, order confirmation, internal notification, or any other type of email.

No manual setup required — just configure the recipient, subject, and message template, and your Agent handles the rest.

📅 Cal.com Booking

Let users book meetings or appointments directly inside the chat.

The new Cal.com Booking action displays your Cal.com scheduling widget seamlessly, allowing customers to pick a time without ever leaving the conversation.

With these new capabilities, your AI Agents can now communicate and coordinate — handling both outbound messages and real-time scheduling, all on autopilot.

We’re thrilled to announce the release of AI Agents – a powerful new way to supercharge your business with intelligence, automation, and control.

What are AI Agents?

AI Agents are smarter, task-oriented assistants built to work for you. Unlike traditional chatbots that require step-by-step flows, AI Agents can:

• Understand intent – detect what your users are asking for, even if they phrase it differently.

• Make decisions – evaluate context and decide the best next step.

• Take action – call APIs, send and fetch data, or collect lead data directly from the conversation.

• Handle complexity – capture data, follow multi-step logic, and deliver personalized outcomes.

Think of them as your company’s “brain + hands” – able not only to respond, but also to do things on your behalf.

Why we built this

Over the past year, we’ve seen Chatling power thousands of interactions across industries – from healthcare to SaaS to e-commerce. Many of you told us:

“Chatling already saves us hours by answering FAQs instantly. But if it could also carry out tasks for customers, it would completely transform how we work.”

We listened. AI Agents are our answer to making your assistant not just reactive, but proactive—an intelligent team member that reduces manual work, drives sales, and improves customer experience.

How to access AI Agents

AI Agents are a standalone product within Chatling. You can set one up directly from your account—just like creating a chatbot.

What’s next

This is only the start. In the coming weeks, we’ll be releasing deeper integrations with tools you already rely on—such as Zendesk, HubSpot, Cal, and more—so your Agents can accomplish even more.
