Build an AI SaaS MVP
LLM, RAG, Billing. 2 Weeks.
An AI SaaS product needs more than a ChatGPT wrapper. It needs a reliable LLM orchestration layer, a RAG pipeline that actually retrieves the right context, usage based billing that tracks tokens and API calls, guardrails that prevent hallucination and prompt injection, and a user experience that makes AI feel like magic, not a chatbox. We build all of it in 14 days.
What Ships in Your AI SaaS MVP
Every feature below is included in the fixed price. This is a production AI product, not a prototype with hardcoded prompts.
Why This Is Not a ChatGPT Wrapper
Not a ChatGPT wrapper
We build production AI with guardrails, evaluation pipelines, and model routing. Your users get reliable, grounded responses, not raw LLM output.
Usage billing from day one
Token tracking, per user quotas, and Stripe integration baked in. You can charge per query, per document, or per seat from launch.
Your data, not theirs
RAG pipeline grounds every response in your users' actual content. No hallucinated answers, no generic responses, no data leaking between tenants.
AI that takes action
Tool use and function calling let your AI search databases, call APIs, generate documents, and trigger workflows. Not just text in, text out.
AI SaaS Architecture
The frontend runs on Next.js with streaming server components for real time AI responses. The backend orchestrates LLM calls through a unified API layer that supports model switching, retry logic, and cost optimization. Documents uploaded by users are chunked, embedded, and stored in a vector database (pgvector for simplicity, Pinecone for scale). Every query hits the RAG pipeline: user input is embedded, relevant chunks are retrieved, and the full context is sent to the LLM with system prompts and guardrails. Stripe tracks token usage per user and enforces plan limits. Redis caches frequent queries. The entire system deploys as three services: frontend on Vercel, API on Railway, and the vector database alongside PostgreSQL on Railway.
Tech Stack
