    Next steps that connect to the tools you already use.

Your customers have questions. Your product should help them move forward.

Answers are spread across your website, FAQs, and documentation. Visitors struggle to find what they need, and your team handles the same questions again and again.

Give customers a way to ask, explore, and act, right where they already are.

Hard-to-find answers
Customers search through pages and articles to find one useful answer.
Disconnected next steps
Getting an answer often means opening another page, filling out a separate form, or waiting for someone to respond.
Complexity for your team
Building a useful AI experience means bringing design, knowledge, agent behavior, and integrations together.

Everything you need to build a useful AI experience.

Langkast brings the interface, knowledge, behavior, and actions together. Build an experience around what your customers need to accomplish.

Frequently asked questions

What is Langkast?

Langkast is a platform for building custom AI experiences for customers, including support and sales agents, AI-powered FAQs, documentation search, and guided workflows.

What can I customize?

Appearance, interaction, voice, knowledge, behavior, actions, and context. In practice: how the experience looks, how people ask and answer, how the agent sounds, which sources it uses, the instructions and boundaries it follows, and the next steps it can offer.

Can I use my existing content?

Yes. Connect your website and documentation, FAQs and help articles, or upload documents. Agents answer from the sources you choose and link back to them.

Can agents take action?

Yes. Agents can collect structured details, create a support request with the conversation attached, send people to the right page, and work with your tools through supported integrations. For example, a pricing conversation can end as an inquiry your sales team receives with full context.

Where can I publish an experience?

On your website, by adding a single script tag, and inside your product.

Do I need to write code?

Not to build. Knowledge, behavior, and design are set up in the builder. Publishing on a website takes one script tag. Passing page or user context into an in-product experience needs a developer.

What happens when an agent cannot answer?

It says so instead of guessing, then offers the next step you defined: collecting details for your team, pointing to a contact page, or handing the conversation to a person.

How is customer data handled?

Your data is never used to train models. It is encrypted in transit and at rest, and Langkast is built to SOC 2 practices. Read the details on our security and privacy pages.

How does pricing work?

Plans are being finalized. Check pricing for the latest, or talk to us about your use case.

Bring your knowledge, design, and workflows together with Langkast.
