Yak
What Yak is
Yak is a cloud AI assistant platform that can be embedded in software products. It answers questions, guides customers, and completes actions by calling customer-provided APIs. Connections include tRPC, GraphQL, REST, custom APIs, and MCP servers whose tools can power chat and voice. For Next.js products, Yak can learn product routes and guide users through them. Tools run within each user’s own access, and Yak is described as seeing only what that user can see. Conversation storage is off by default for new applications; customers can enable it and choose retention up to a plan maximum. Features listed include hands-free voice, mockups, product grids, data tables, attachments, personalization, and conversation analytics. AI messages and voice minutes are billed separately, while tool calls and internal processing are included. PAYG costs nothing with usage charges; paid plans start at $800.00 per month.
