What problem does it solve?

This Skill helps you identify potential unintentional lyric borrowing by comparing your song lyrics against likely matches found via web search and LLM knowledge.

Core Features & Use Cases

Distinctive phrase extraction: Pulls ranked 4–7 word n-grams (with cliches filtered) to focus searches on memorable wording.
Web + deep comparison: Searches top suggestions, fetches relevant pages, and classifies overlap as exact, partial, or thematic.
LLM knowledge check: Scans all lyric lines to flag lines that resemble well-known song lyrics and labels the suspected source.

Quick Start

Run plagiarism-checker with your album name and track slug, for example checking only track 03 before releasing it.

FAQPage Schema

How do I check my song lyrics for plagiarism before a music release?▼

To check song lyrics for plagiarism before a music release, this Skill extracts distinctive phrases and uses web search plus LLM-based similarity reasoning to flag potential borrowing. It delivers a structured risk report with HIGH, MEDIUM, or LOW verdicts for your tracks.

What is the best way to detect unintentional lyric borrowing across an entire album?▼

The best way to detect unintentional lyric borrowing across an album is to run a plagiarism check using extracted streaming lyrics. The Skill compares distinctive n-grams against web matches and LLM knowledge to identify exact, partial, or thematic overlap.

Can I run a plagiarism detection check on an individual track slug instead of a full album?▼

Yes, you can run plagiarism detection on an individual track slug by providing the album name and the specific track slug. The Skill supports pre-release checks for single tracks using extracted streaming lyrics with a fallback for alternate lyric formats.

How does semantic comparison work for finding similar song lyrics?▼

Semantic comparison for finding similar song lyrics works by extracting 4-7 word n-grams, filtering cliches, and fetching top web search suggestions. The Skill then classifies the lyrical overlap as exact, partial, or thematic using deep LLM reasoning.

What happens if my track does not have standard streaming lyrics available?▼

If standard streaming lyrics are not available, the plagiarism check uses a fallback for alternate lyric formats. This ensures the semantic comparison can still process your text and generate a structured risk report for the music release.
