🚀 The future of AI for work isn’t general — it’s purpose-built and precise.
After my last post, several people asked me to compare Lio by Aqmen AI with Excel’s native AI assistants. So I ran the exact same prompt again, this time adding Shortcut AI to the previous comparison with ChatGPT and ChatGPT Agent Mode from OpenAI.
Then I asked ChatGPT itself to score the Excel models produced by each tool.
📊 Result: unchanged. Lio by Aqmen AI drastically outperforms everything else. See image below.
(Last time Lio scored 9/10; this time 10/10 on the same Excel — showing that LLMs are stochastic. This randomness is exactly why you don’t want an AI agent writing your spreadsheet cell by cell.)
💡 Why does Lio win?
Because Lio never writes the Excel at all.
🧩 The logic is captured first through clear entities like dimensions, segments, drivers, and expressions.
✅ Once the user approves that logic, the Excel is generated programmatically, not guessed by an LLM.
That means:
❌ No hallucinations
❌ No ambiguity
❌ No formula errors
➡️ Just deterministic precision.
🧠 How to do it right (for any structured workflow):
1️⃣ Codify the workflow → break it into clear, reusable entities (objects, variables, relationships, rules). Domain expertise is key here!
2️⃣ Human-in-the-loop → experts validate the logic before execution.
3️⃣ Programmatic generation → once approved, outputs (Excel, reports, dashboards) are produced deterministically from those definitions.
This recipe works anywhere precision matters (finance, engineering, biology, operations), not just market sizing.
🍝 Example: Dry Pasta in Brazil
AI might suggest a relationship like
➡️ Q = Total population × Penetration × Annual consumption
Once the user validates this logic, the mapping of that formula into the Excel model becomes fully programmatic. Every instance is generated automatically, referencing the correct cells across hundreds or thousands of rows.
You don’t want an AI agent rewriting that equation cell-by-cell. That’s inefficient, error-prone, and FUNDAMENTALLY the wrong use of intelligence.
🎯 Takeaway
In structured, high-stakes workflows, vertical AI beats general AI every time.
If you care about accuracy, auditability, and speed, specialization wins.
