## What it is
typos is a fast source code spell checker written in Rust that finds and corrects spelling mistakes in codebases. It is designed for low false positives so it can run on pull requests and monorepos, with integrations for GitHub Actions and pre-commit.

## Use cases
- find spelling mistakes in my source code
- auto-fix typos across a repository
- add a spell check step to CI for pull requests
- check a monorepo for typos quickly
- run a spell checker as a pre-commit hook
- ignore intentional identifiers like names and acronyms in spell checking

## When to choose
- you need fast spell checking that scales to large monorepos
- you want low false positives suitable for PR checks
- you need CI or pre-commit integration for typo detection
- you want automatic typo correction with configurable ignores

## When to avoid
- you need grammar or prose-quality checking, not just spelling
- you need natural-language document spell checking with rich formatting support
- you require a GUI-based spell checking workflow
