Keiki

Keiki is a hosted multichannel agent platform and developer SDK from Zero Email, Inc., a Delaware corporation. The about page says teams create one agent with instructions, memory, tools, and boundaries, then launch it on SMS, iMessage, WhatsApp, Slack, Telegram, and email. It is a separate product from Keiki World, the children's learning app at keiki.app.

On October 30, 2026, Keiki published a Vercel Connect integration: an agent deployed on Vercel can answer on those channels while its code, model, and deployment stay on Vercel. The project does not store a channel credential or a Keiki secret. The consent screen grants one agent.

The pricing page calls its Starter, Pro, Max, and Enterprise cards a preview and says they are not purchasable yet. Checkout shows the current offer.

Pricing: Checked October 31, 2026. The pricing page says "Plan preview. Contact us for current pricing and availability." A question on that page asks "Can I purchase a proposed plan?" and the answer is "Not yet." The cards are staged in billing and open at launch. Creating an account does not select one of them, and checkout shows the current offer. The preview cards are labeled Starter, Pro, Max, and Enterprise. The page says phone lines are optional and billed separately, and that until launch the channel setup shows the current provider price before purchase.
