The ChatGPT Enterprise alternative built on your own data.
ChatGPT Enterprise gives your team a general-purpose AI assistant with per-seat pricing. TailorStack builds AI applications purpose-built for your specific use cases — on your data, on your infrastructure, for a one-time price.
ChatGPT Enterprise is a general-purpose chatbot — it doesn’t know your products, processes, or internal documentation.
Per-seat pricing (£40–60/user/month) scales to six figures as adoption grows across the organisation.
Your data uploaded to OpenAI’s platform is governed by their policies, not yours.
Custom GPTs are limited in what they can access — real integration with your databases and APIs requires custom development anyway.
No RAG pipeline — the model can’t search your full document corpus in real time.
What you get instead
AI applications built for your specific use cases. RAG pipelines that search your entire document corpus in real time. Custom interfaces for different teams — sales, support, legal, operations. Your data stays on your cloud infrastructure. Direct API calls to OpenAI, Anthropic, or any model provider — no per-seat markup. Built in 4–6 weeks.
