Build customer-facing AI agents for support, sales, and product guidance
Write instructions in plain language, choose a model, set guardrails, and connect the knowledge the agent is allowed to use.
Let agents look up orders, fetch invoices, create tickets, or trigger workflows, and reply with interactive components instead of plain text.
Publish one agent to a website chat bubble, help center, phone line, WhatsApp, email, and Slack without rebuilding it per channel.
Humans and agents work from the same conversation view, with context and history preserved when an issue escalates.

No-code AI assistants trained on your own content
Connect websites, sitemaps, Notion workspaces, Google Drive files, Zendesk help centers, Gitbooks and PDFs instead of rebuilding a knowledge base from scratch.
The assistant collects purchase intents, books calls and qualifies visitors automatically, turning support conversations into pipeline.
Visitors can ask in their own language even when the underlying knowledge base is written in another, with replies returned in the user's language.
Publish as a customizable web widget, a Slack app or an HTTP API, with guided integrations for WordPress, Webflow, Wix, Squarespace and Shopify.
