Overview
Claude’s integration with Excel represents a fundamental shift from AI model competition to workflow integration. The author built an 11-tab financial model in just 10 minutes that would normally take weeks, demonstrating that the real AI race is now about embedding intelligence into workflows rather than just building better models.
Key Takeaways
- Workflow integration beats model competition - The future belongs to AI systems embedded in existing tools with proprietary data access, not just better chatbots
- Structural awareness transforms productivity - AI that understands cell relationships, formulas, and dependencies can compress weeks of analytical work into minutes
- Data partnerships create competitive moats - Access to institutional data sources (LSE, Moody’s, S&P) that competitors can’t easily replicate becomes the real differentiator
- Vertical specialization wins over horizontal dominance - Multiple specialized AI systems optimized for specific domains will outperform one-size-fits-all solutions
- Infrastructure providers capture value regardless - Cloud platforms like Microsoft Azure profit from hosting AI models whether their own or competitors’ models succeed
