## What it is
NoteCalc is a browser-based notepad with a smart built-in calculator, written in Rust and compiled to WebAssembly. It aims to be a free, self-hostable alternative to Soulver, letting users mix notes and inline calculations.

## Use cases
- do quick calculations while taking notes in the browser
- self-host a free Soulver alternative
- mix text and math on a scratchpad
- compute with units, matrices, and linear algebra inline
- run a smart calculator locally via Docker

## When to choose
- you want Soulver-style inline calculations for free in a browser
- you need a self-hostable calculator notepad
- you prefer a lightweight tool that works offline in the browser

## When to avoid
- you need full spreadsheet features or cell references
- you require currencies, financial functions, or user-defined functions, which are still on the roadmap
- you need a native desktop calculator app

## Facets
- artifact type: application
- maturity: active
- function: gui, math, editor
- domain: developer-tools, mathematics
- platform: wasm, rust, browser, self-hosted
- tags: calculator, notepad, soulver-alternative, smart-calculator, note-taking, wasm, web-server
