The Microsoft Copilot alternative purpose-built for your business.

Microsoft Copilot adds AI to Office 365 — but it’s a generic assistant that doesn’t understand your business processes, your data structures, or your industry. TailorStack builds AI applications designed for your specific workflows at a lower total cost.

Why teams leave Microsoft Copilot

  • Copilot is a generic AI layer across Office 365 — it can’t be trained on your specific business logic or domain knowledge.
  • Per-user pricing (£25–30/user/month) on top of existing M365 licensing pushes costs to six figures for mid-size teams.
  • Your proprietary data and prompts flow through Microsoft’s cloud — data residency and compliance concerns remain.
  • Copilot works within Microsoft apps — it can’t integrate with your non-Microsoft tools, databases, or internal systems.
  • The AI capabilities are broad but shallow — no deep integration with your CRM, ERP, or industry-specific workflows.

What you get instead

AI applications purpose-built for your actual workflows. RAG pipelines that connect to your databases, CRM, document stores, and internal tools — not just Office files. Custom interfaces designed for specific team use cases. Your cloud infrastructure, your data governance. Model flexibility — OpenAI, Anthropic, or open-source. Built in 4–6 weeks.
