Nummo turns natural language into precise, auditable models. Build, edit, and validate your spreadsheets with the speed of AI and the reliability of machine-verified logic. Think in English. Model in seconds. Trust every cell.
Legacy spreadsheets were never built for the AI era. Nummo introduces a new modeling substrate that gives both humans and machines a complete understanding of your model's logic, structure, and meaning. This lets you make changes confidently, collaborate without breaking anything, and validate updates with full clarity.
Nummo knows 'Revenue' is a metric, not just Cell B12.
Changes cascade intelligently through the system.
Warns about inconsistencies before they become errors.
Nummo combines the flexibility of a spreadsheet with the rigor of software engineering.
Tell Nummo the change you want, and it transforms your instructions into exact, validated model updates.
Nummo constantly validates the entire model, checking references and ensuring consistency.
No more endless file versions. Snapshots, branches, merging, and diffs built in.
Multiple analysts can work on the same model simultaneously without conflict.
A semantic representation of your model that AI can understand and manipulate safely.
Every action comes with a full explanation. See what changed, how, and why.
Models run locally by default. Your data stays on your machine unless you choose to sync.
Create and reuse validated modeling components like SaaS metrics or DCF frameworks.
Nummo isn't just a tool. It's a suite of specialized AI agents that work alongside you.
Nummo uses a multi-layer engine that captures every table, reference, assumption, and dependency inside your model.
Ensures consistency across all sheets.
Transforms natural language into structured operations.
Applies operations deterministically with validation.
Shows changes across structure, formulas, and data.
Eliminate manual cell editing and formula errors. Get the clarity of code with the speed of natural language.
Work from a single source of truth. Assumptions are clear, edits are safe, and collaboration is controlled.
Trust your models. Reviews are faster, scenarios are easier to explore, and forecasts are more reliable.
Run locally, integrate with internal LLMs, and enforce strict data policies for regulated environments.
Nummo takes data integrity and privacy seriously. Local-first architecture ensures sensitive financial data never leaves your device unless you explicitly choose to sync.
