Your product, powered by conversation

Add an AI assistant that drives your product for your users. yak connects to your existing APIs—users chat or speak, and the assistant navigates pages and takes real actions on their behalf, all through your real auth and your real data.

5 minutes to integrate. One prompt with AI.

Full product integration takes 5 minutes of developer time—or a single query if you use an AI coding assistant.

Install the SDK

Add yak to your Next.js, React, Vue, Svelte, Nuxt, Angular, or vanilla JS app. Works like any npm package you already use.

Connect your API

Point yak at your tRPC routers, REST endpoints, or GraphQL schema. The AI understands your API automatically.

Users chat or speak

Embed one widget. Users type questions, or flip on voice mode and talk—yak executes real API calls and delivers real answers either way.

Connect your knowledge, not just your APIs

Connect any remote MCP server—Zendesk, Notion, Confluence, GitHub, or your own internal one. An admin authorizes it once and every chat and voice session can use it. No code, no per-provider integration to maintain.

Connect once

From the dashboard, an admin authorizes a provider's MCP server with a single OAuth click. No engineering work.

Choose the tools

Expose read-only knowledge lookups and keep the rest off with a per-provider allowlist. The same settings power chat and voice.

Answers from real data

Tools run server-side—credentials stay on the backend, never in the browser—so users get answers grounded in your knowledge base.

Not just a chatbot. A product expert.

Generic chatbots answer FAQs. yak connects to your APIs and actually does things—it queries real data, executes real actions, and responds with information specific to each user.

Queries your real data — orders, products, user accounts, whatever your API exposes

Executes real actions — updates settings, processes requests, triggers workflows

Respects your permissions — uses your existing auth, never bypasses access controls

Remembers each user — pass a signed identity and conversations persist per user, ready to resume on any device

You had 12 orders last month. 2 shipped late: Order #4821 (3 days) and #4856 (1 day). Both were during the holiday surge. Want me to check if any refunds apply?
