Build AI SaaS on a foundation that already bills customers
Most Next.js AI SaaS starter content stops at a chat demo. TurboStarter ships AI tooling on top of auth, billing, organizations, feature flags, and deploy-ready infrastructure — so you are not duct-taping OpenAI calls onto a blank Next.js app.
If you are evaluating an AI SaaS starter kit, the hard parts are usage metering, plan gating, streaming UX, and keeping API keys out of the client — not calling openai.chat.completions.create.
Start with AI Kit for streaming chat, tool calling, and mobile AI templates — add it to Core when you are ready to ship AI features.
