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.

Open-source platform for building no-code RAG AI chatbots
Create a RAG chatbot by giving a URL to crawl or uploading files; no coding or API plumbing required.
Built on the OpenAI Assistants and Responses APIs, supporting models such as GPT-4o and GPT-3.5 with improved tool calling.
Let the bot query API endpoints with specific parameters and search the web so answers stay current.
SAML/SSO authentication for private employee chatbots, lead capture, file attachments, and chat disclaimers.
