My Personal AI Stack in 2026

Short summary

A developer shares their simplified 2026 AI stack: ChatGPT for ideation, Cursor for AI-powered coding, GitHub as the source of truth for code and AI assets, MCP for connecting tools through standardized interfaces, a structured prompt library for reusable assets, and FastAPI for exposing AI capabilities via APIs. The core philosophy is choosing tools that work well together over chasing the newest models.

• •ChatGPT serves as the primary thinking partner; Cursor handles AI-powered development
• •MCP adoption was the biggest workflow improvement, enabling connected AI systems over isolated tools
• •A structured prompt library and GitHub-based versioning turn AI assets into maintainable software assets
