CalPal

CalPal is a smart notepad calculator that combines the flexibility of a text editor with the power of mathematical computation. Unlike traditional calculators, CalPal lets you write calculations naturally with variables, formulas, and plain English, while automatically computing results as you type. It supports advanced features like variable tracking, aggregation functions (total, mean), unit conversions, timezone coordination, and AI-powered assistance through Google Gemini integration.

CalPal transforms how you work with numbers by combining the flexibility of a notebook with the intelligence of AI. Simply type your thoughts, numbers, and questions naturally, and CalPal handles the rest.

Getting Started:

1. Open CalPal and start writing your calculations in plain language
2. Define variables by simply writing "revenue = 50000" or "tax rate = 15%"
3. Ask questions like "What's my net income after 15% tax?" and CalPal calculates automatically
4. Mix formulas, notes, and calculations in one fluid workspace
5. Reference previous calculations and variables anywhere in your notebook
6. Let the AI suggest formulas and catch errors as you work

Natural Language Calculations Write math expressions naturally with variables and formulas like a notebook, results compute automatically.

Variable Tracking Define variables once (e.g., salary = 5000) and reuse them throughout your calculation with a live variables sidebar.

Aggregation Functions Use built-in functions like total, mean(results) to sum previous lines or calculate statistics effortlessly.

Unit Conversions & Mixed Units Calculate with different units (100 km in miles, 5 km + 2000 m) and CalPal handles conversions automatically.

Timezone Coordination Track team members across timezones and coordinate meeting times with automatic timezone calculations.

AI-Powered Assistance Enable Google Gemini AI integration to understand natural language requests like "Plan a trip to Paris" and generate calculations.

Save & Share Save calculations locally or share them with others via a simple share link.

#1 Personal Finance & Budgeting Calculate net pay, taxes, expenses, and track financial variables with automatic updates when you change values.

#2 Quick Math & Problem Solving Solve everyday math problems, percentage calculations, and unit conversions without switching between tools.
