AI agents that answer, organize your customers, and spread the word.
Certu takes manual work off your business's plate that a machine does better.
Our commitment
Technology that gives back, not hoards
Certu is an AI company that chose not to keep everything it earns. Part of what is left goes back to our customers, and part goes to those who could never afford it.
1%
of our revenue becomes donations, shared every month with receipts
The rule is ready and starts to apply as the customer base grows.

How we work
Set it up in minutes. No meetings, no installation.
- 1.Paste your website or Instagram. Certu reads what is already online about your business and builds the first version of the agent on its own.
- 2.Connect your WhatsApp. It is just like opening WhatsApp Web. Your number stays yours, and you can jump in and answer whenever you want.
- 3.Fine-tune and test. Fix prices, hours, and tone of voice in the Dashboard, chat with it until it fits your business, and every adjustment takes effect in the very next conversation.
Build yours and chat with it
It takes a few minutes and needs no sign-up. You talk with the agent before deciding anything.
Create my agentStart free, no credit card needed. Or chat on WhatsApp: the AI agent itself answers you.
