Let customers text your product.

We build an agent from your site that you can test. Or bring your own

Live with customers at these companies

Go live in minutes, not months.

Build your agent on Keiki or bring your own, then connect your API, MCP server or docs. Everything else is already built for the conversation.

Describe your agent’s job

Say what the agent should do in a sentence, or start from your website. Keiki builds the agent and gives it a number on iMessage, WhatsApp and email.

Build an agent

Teach your agent the business

Add your site, docs and policies, connect Shopify or Stripe, or point the agent at your own API. It answers from your sources, not a guess.

How Knowledge works

Production-ready. Just wire up your app.

Threaded replies, tapbacks and typing work the way people text. Point the agent at your API and it checks the order and changes the delivery right in the thread.

How replies and reactions work

Already have an agent? Bring it.

Keep your model and prompt. Keiki handles the numbers, the channels and delivery. Write tools in TypeScript, call the API or connect over MCP.

Read the docs

One agent, every channel.

Customers use your product by texting your agent on iMessage, WhatsApp, Slack, Telegram or email. Nothing to download, no login.

Every conversation, in your control.

Every reply, tool call and trace, in order, in one place. Take over any chat when it matters, or leave your agent a note for next time.

Every conversation, live

Chats from every channel land in one inbox. When the agent isn’t sure, it tells the customer a person is on it and flags the chat for you.

Open your inbox

Step in anytime

Leave a note and the agent’s next reply follows it, or take over.

See what’s working

What your agents handled and what came to you, each day.

How Signals work

Sell right in the chat.

Your agent answers the question, takes the payment with Apple Pay and comes back for the reorder. You don’t lift a finger.

Take payment in the thread

Apple Pay with Face ID, right in the conversation. No checkout page and no link to lose.

How payments work

Bring them back

Reminders and check-ins on a schedule you set. Running low turns into a reorder with one reply.

Questions

Setup, channels, pricing and control.

Talk to a human

Keiki gets your agent live with real customers on iMessage, WhatsApp, Slack and email. Connect your product or bring your own agent. Keiki handles the numbers, delivery, memory and the inbox, and you can see every conversation and action.

A number gets you a way to send and receive texts. Everything after it is still yours to build: the agent, memory, your tools, other channels, an inbox and handoff to your team. Keiki is all of that, ready on day one.

No. Build it in the dashboard or start from a template. Developers can add their own tools through the SDK and API.

Customers text its number on iMessage or SMS, or message it on WhatsApp, Telegram or email. Your team reaches it in Slack and Teams. Each channel has its own setup and charges.

Yes. In iMessage the agent sends a Pay card, and the customer pays with Apple Pay and Face ID without leaving the thread. The money goes to your own Stripe account, and the agent can only ask for amounts within the limits you set. How it works

Yes. Connect your API, MCP server or the apps you already use, and choose what the agent can do. No API yet? Write the actions in Keiki.

It doesn’t guess. It tells the customer a person will follow up, flags the conversation in your inbox and waits. You reply yourself or leave the agent a note, and it picks up from there.

Every action is checked against the customer’s account, and the ones you mark wait for approval. You can read every conversation and step in at any time.

Yes. Keep your model, prompt and framework where they run today. Keiki handles the channels, delivers the replies and records every turn. Start with the external harness or Vercel Connect.

Plans include monthly credits for agent usage. The pricing page covers plan features, credits and iMessage lines, and you can track usage in your workspace.
