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
