Markdown-Driven Mind Maps: The Architecture Behind Affordable AI Streaming

By making Markdown the single source of truth for mind map data, this approach creates a diff-friendly, lightweight format that makes real-time AI streaming computationally efficient. This design philosophy demonstrates how architectural constraints—choosing plain text over proprietary formats—compound into surprising benefits for AI-driven applications. For tool builders, it illustrates why data model choices upfront can unlock both technical elegance and practical cost savings.
