Features Overview

Minttu lives inside Excel as your intelligent financial modeling assistant. Here's what makes it powerful.

Core Capabilities

Natural Language Interface

Talk to your spreadsheets in plain English. Minttu understands the context of your workbook—cell references, formulas, and data structures—so you can ask questions naturally.

Example queries:

• "What are the revenue assumptions in this model?"
• "Show me all cells that depend on the discount rate"
• "What's the total CapEx across all project phases?"

When Minttu answers, it provides citations pointing to the exact cells where it found the information.

Workbook Editing

Describe the changes you want, and Minttu implements them directly in your Excel workbook. No need to manually find cells or write complex formulas.

Example requests:

• "Add a sensitivity table for electricity prices"
• "Update the construction timeline to start in 2026"
• "Create a new sheet summarizing key outputs"

Model Creation

Build complete financial models from scratch by describing your requirements. Minttu is particularly effective for:

• Project finance models (solar, wind, infrastructure)
• DCF valuations
• LBO models
• Operating budgets and forecasts

Processing Modes

Fast Mode

Optimized for speed. Use when you need:

• Quick cell lookups
• Simple calculations
• Minor formatting changes
• Straightforward Q&A

Standard Mode

The recommended default for most tasks. Provides a balance of:

• Thorough analysis
• Reasonable response times
• Good accuracy on typical financial modeling tasks

Expert Mode

For complex, multi-step operations:

• Creating new financial models from scratch
• Long-winded prompts with many requirements
• Tasks involving multiple interconnected sheets
• Complex formula generation with dependencies

Intelligent Surveys

When you ask Minttu to create or edit something complex, it may present a survey form to gather essential parameters before proceeding.

Why Surveys?

Financial models require precision. Rather than making assumptions, Minttu asks clarifying questions to ensure the output matches your needs.

What Surveys Capture

For a typical project finance model, surveys gather:

• Project basics — Technology, capacity, location
• Timeline — Construction period, operational life
• Revenue structure — PPA terms, merchant exposure, price assumptions
• Cost structure — CapEx breakdown, OpEx categories
• Financing — Debt/equity split, interest rates, loan terms
• Tax and accounting — Depreciation methods, tax rates

Survey Benefits

Workbook Analysis

Minttu can analyze existing workbooks to:

• Understand model structure and flow
• Trace formula dependencies
• Find specific values using semantic search
• Identify calculation errors or inconsistencies

Data Flow

Your Request → Minttu Analyzes Workbook → Survey (if needed) → Executes Changes → Updated Workbook

For Q&A queries, Minttu reads your workbook, finds relevant cells, and responds with citations. For creation/editing tasks, it gathers parameters, generates a detailed plan, and implements changes directly in Excel.
