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 sales assistant for WhatsApp, Instagram and Messenger
Describe your business once — products, prices, FAQs and tone — and the assistant answers like a trained salesperson without any flow programming.
One assistant replies on WhatsApp, Instagram Direct and Messenger, so customers get consistent answers wherever they write.
Customers can send audio messages and the assistant replies the same way it would to typed text, which matters in voice-heavy markets.
Select an audience, write the message and push it out to everyone in seconds for promotions and re-engagement.
