## What it is
lemmeknow is a fast Rust CLI tool and library that identifies mysterious text, strings, and files using regex-based pattern matching (e.g., YouTube IDs, hashes, IPs, crypto). It can also be used as a Rust library with JSON output for programmatic use.

## Use cases
- identify what a mysterious string is
- analyze hard-coded strings from malware or network captures
- identify strings in a file during CTF forensics
- programmatically classify text tokens in Rust
- find hashes, IPs, URLs, or encoded data in text

## When to choose
- you need a fast, cross-platform CLI to identify unknown strings or file contents
- you want a Rust library for string identification with JSON output
- you're doing CTF challenges, malware analysis, or network forensics

## When to avoid
- you need deep semantic analysis or NLP of text rather than pattern matching
- you need a Python tool with a large pattern ecosystem (consider PyWhat)
- you need identification of binary file formats rather than text patterns
