## What it is
SoulverCore is a Swift framework providing a natural language math engine that evaluates expressions like '65 kg in pounds' or '$25k over 10 years at 7.5%'. It powers the Soulver notepad calculator and is distributed as a closed-source xcframework, free for non-commercial use with a license required for commercial use.

## Use cases
- evaluate natural language math expressions in a Swift app
- convert units and currencies from plain-English phrases
- parse and calculate dates and calendar arithmetic
- build a notepad-style calculator app
- compute percentages and compound interest from text
- convert times between time zones via natural language

## When to choose
- you need a powerful natural language calculation engine in Swift on Apple platforms
- you want high performance expression evaluation with no third-party dependencies
- your use is personal or non-commercial, or you can purchase a commercial license

## When to avoid
- you require fully open-source code you can inspect or modify
- you need a free solution for commercial products
- your project is not in Swift or does not target supported platforms
