Langkast is the complete platform for building and deploying AI support agents — agents that answer customer questions instantly, take real actions like refunds and order lookups, and escalate to humans with full context.

How does the agent learn my business?

Connect your sources — help center, website, PDFs, past tickets — and the agent trains on them automatically. Content re-syncs on a schedule so answers stay current.

What happens when the AI can't answer?

Smart escalation routes the conversation to your team with the full transcript, a summary, and customer context — so customers never repeat themselves.
