Plagiarism Checker

抄袭检查器

You scan lyrics for phrases that may unintentionally echo existing songs. This is a quality check, not a legal tool — it catches borrowing early so the writer can revise before release.
你需要扫描歌词中是否存在无意识与已有歌曲相似的语句。这是一项质量检查工具，而非法律工具——它能提前发现借鉴情况，以便创作者在发布前进行修改。

Workflow

工作流程

Step 1: Get Lyrics

步骤1：获取歌词

  • Use 
    extract_section(album_slug, track_slug, "streaming")
    to get streaming lyrics (preferred — no phonetic spellings that confuse web searches)
  • If streaming lyrics empty, fall back to 
    extract_section(album_slug, track_slug, "lyrics")
    for Suno lyrics
  • If raw text was provided instead of album/track reference, use that directly
  • 使用
    extract_section(album_slug, track_slug, "streaming")
    获取流媒体歌词（优先选择——避免会干扰网络搜索的音标拼写）
  • 如果流媒体歌词为空，则退而使用
    extract_section(album_slug, track_slug, "lyrics")
    获取Suno歌词
  • 如果提供的是原始文本而非专辑/曲目引用，则直接使用该文本

Step 2: Extract Distinctive Phrases

步骤2：提取具有辨识度的语句

Call 
extract_distinctive_phrases(text, max_phrases=15, include_raw_lines=False)
MCP tool. This returns:
  • Distinctive 4-7 word n-grams ranked by section priority (top 15)
  • Pre-formatted search suggestions with quoted phrases + "lyrics"
  • Common cliches already filtered out
调用MCP工具
extract_distinctive_phrases(text, max_phrases=15, include_raw_lines=False)
。该工具会返回：
  • 按段落优先级排序的4-7词独特n元语法（前15个）
  • 带引号语句+"lyrics"的预格式化搜索建议
  • 已过滤掉常见陈词滥调

Step 3: Web Search

步骤3：网络搜索

  • Search the top 10-15 
    search_suggestions
    returned by the tool using WebSearch
  • For short lyrics (<100 words), limit to 5-8 searches
  • Look for results that reference specific songs by title/artist
  • Skip results that are:
    • Lyrics aggregator sites listing hundreds of matches (too generic)
    • Dictionary/reference pages
    • The user's own published work
  • 使用WebSearch对工具返回的前10-15条
    search_suggestions
    进行搜索
  • 对于短歌词（少于100词），限制为5-8次搜索
  • 查找提及特定歌曲标题/歌手的结果
  • 跳过以下结果：
    • 列出数百个匹配项的歌词聚合网站（过于泛化）
    • 词典/参考页面
    • 用户已发布的自有作品

Step 4: Deep Compare

步骤4：深度对比

For any search result that names a specific song:
  1. WebFetch the lyrics page
  2. Compare the matching section against the user's lyrics
  3. Check if the match is:
    • Exact consecutive words (5+) — HIGH risk
    • Partial overlap (4 words) — MEDIUM risk
    • Thematic similarity only — LOW risk
对于任何提及特定歌曲的搜索结果：
  1. 使用WebFetch获取歌词页面
  2. 将匹配段落与用户的歌词进行对比
  3. 判断匹配类型：
    • 连续5个及以上完全匹配的单词——高风险
    • 部分重叠（4个单词）——中风险
    • 仅主题相似——低风险

Step 5: LLM Knowledge Check

步骤5：LLM知识库检查

Independently scan ALL lines of the lyrics (not just extracted phrases) using your training knowledge:
  • Flag any line that closely resembles a well-known song lyric
  • Include the suspected source song and artist
  • Note whether the similarity is in words, melody hook phrasing, or concept
利用你的训练知识库独立扫描歌词的所有行（不仅是提取的语句）：
  • 标记任何与知名歌曲歌词高度相似的行
  • 包含疑似来源歌曲和歌手信息
  • 注明相似性是体现在文字、旋律钩子语句还是概念上

Step 6: Generate Report

步骤6：生成报告

Risk Levels

风险等级

LevelCriteriaAction
HIGH5+ consecutive matching words from a known song, especially chorus/hookRewrite the line immediately
MEDIUM4-word match from known song, or structural similarity flagged by LLMReview and consider rewording
LOWCommon phrasing overlap, likely coincidenceNote for awareness, no action needed
等级判断标准行动建议
高与知名歌曲存在5个及以上连续匹配的单词，尤其是副歌/钩子部分立即修改该行
中与知名歌曲存在4个单词匹配，或LLM标记存在结构相似性审核并考虑改写
低常见语句重叠，大概率为巧合仅作记录，无需采取行动

Important Notes

重要说明

  • This is not a legal tool. It catches likely borrowing, not copyright infringement. Only a lawyer can determine infringement.
  • Streaming lyrics preferred. Suno lyrics contain phonetic respellings (e.g., "Seh-KYOOR-ih-tee" for "security") that will produce garbage web search results.
  • Common cliches are pre-filtered. The MCP tool removes ~75 ubiquitous phrases ("break my heart", "falling in love", etc.) before returning results. These are too common to flag.
  • Web searches may fail. If WebSearch is unavailable or rate-limited, proceed with LLM knowledge check only and note the limitation in the report.
  • Not a pre-generation gate. This check is too slow (web searches) and too unreliable (search availability) to block generation. Run it before release, not before Suno.
  • 这不是法律工具。它能发现可能的借鉴情况，但无法判定是否构成版权侵权。只有律师才能做出侵权判定。
  • 优先使用流媒体歌词。Suno歌词包含音标拼写（例如将"security"写成"Seh-KYOOR-ih-tee"），会导致网络搜索结果无效。
  • 常见陈词滥调已预先过滤。MCP工具在返回结果前会移除约75个普遍使用的语句（如"break my heart"、"falling in love"等）。这些语句过于常见，无需标记。
  • 网络搜索可能失败。如果WebSearch不可用或受到速率限制，则仅进行LLM知识库检查，并在报告中注明该限制。
  • 不是生成前的检查关卡。该检查速度较慢（需网络搜索）且可靠性受搜索可用性影响，因此不适合在生成前进行拦截。应在发布前运行，而非在Suno生成前。

Running for Full Album

针对整张专辑运行检查

When given an album slug without a specific track:
  1. List all tracks via 
    list_tracks(album_slug)
  2. Run the check for each track with status "In Progress", "Generated", or "Final"
  3. Skip tracks with status "Not Started" or "Sources Pending"
  4. Aggregate findings into a single album-level report with per-track sections
当仅提供专辑slug而未指定具体曲目时：
  1. 通过
    list_tracks(album_slug)
    列出所有曲目
  2. 对状态为“In Progress”、“Generated”或“Final”的每首曲目运行检查
  3. 跳过状态为“Not Started”或“Sources Pending”的曲目
  4. 将所有发现整合到一份包含单曲目章节的专辑级报告中
