300+ hours of work,
delivered in one repo
Every feature a production AI SaaS needs — built, tested, and wired together. Clone the repo, tell Claude what product you are building, and it will help you customise these features in hours — not months.
Multi-Model AI Chat
GPT-4o, Claude 3.5, streaming responses, conversation history, model switching, token tracking per user.
Complete Auth System
Google & Microsoft OAuth, email/password, forgot password, JWT sessions, GDPR consent — NextAuth v5.
Stripe Billing Built In
Free/Pro/Enterprise plans, subscriptions, webhooks, customer portal, invoice history, usage-based top-ups.
3-Step Onboarding Flow
New users are guided through "what are you building" → choose AI template → launch. No confusion on first login.
Smart Upgrade Prompts
When a Free user hits 80% of their token limit, a banner appears. Hit a Pro feature, a modal appears. Revenue drives itself.

What you can launch with this codebase
The infrastructure is done. You bring the idea and the customers.
Niche AI Chatbot
Pick a niche — legal, HR, real estate, finance, medical. Set a system prompt. Deploy. Charge $19-99/mo per user. The billing, auth, and AI layer are already built — you just add the expertise.
Document Q&A Tool
Users upload PDFs, contracts, or reports. AI reads them and answers questions. File upload is built. RAG pipeline hooks are ready for Pinecone. You add the domain knowledge.
White-Label AI for Clients
Put your client's branding on it. Deploy as their own AI tool. Multi-tenancy is built in — each client gets their own org, users, and usage limits. Charge $5,000-15,000 per client project.
AI Writing Tool
Cold emails, job descriptions, product descriptions, blog posts. The prompt template system is built and seeded. You add your niche templates and deploy. Charge $19-49/mo.
AI API Product
Expose AI endpoints to paying developers. API key management, rate limiting per plan, usage billing by token — all built. You choose the AI specialisation, they call your API.
Internal Company Tool
Deploy for your own team or a client company. Staff log in, use AI for internal tasks. Role-based access, audit logs, and an admin panel to manage users — all included.
99% of the product is already built.
You just focus on your idea.
Every integration that takes months to build — auth, Stripe, AI models, emails, admin panel, onboarding, deploy pipeline — is already wired together and working. You do not touch any of that. You just describe your product, make a few changes to the right files, test locally, and deploy. Done.
🔐 Auth
Google, Microsoft, email — already works. You never touch it.
💳 Billing
Stripe plans, webhooks, invoices — all wired. Change the prices to yours.
🤖 AI Models
GPT-4o, Claude 3.5 — connected. Just set your system prompt.
📧 Emails
Welcome, alerts, receipts — all sending. Change the sender name.
🚀 Deploy
Vercel config is ready. One command and your product is live.
👑 Admin Panel
User management, usage stats — all there. Log in and manage.
💬 Stuck on something? Just ask an AI.
Every file in this codebase is clean, structured, and written in standard Next.js + TypeScript — the most documented stack in the world. Paste any file into Claude or ChatGPT and ask "how do I change this for a legal chatbot?" or "add a $9/mo plan" — you will get a working answer in seconds. You do not need to be a senior developer. You just need to be willing to follow instructions.
