  "Canvas to Markdown for Gemini" is a seamless tool designed to bridge the content you create in Gemini's Canvas directly into your everyday workflow.
  
  With this extension, you can extract math formulas (LaTeX), Mermaid diagrams, tables, and more into Markdown, retaining 100% of their original structure.
  
  We’ve also added an innovative feature for exporting source code. Since the original Canvas data lacks programming language metadata, normal exports strip away syntax highlighting. To solve this, our extension performs advanced code analysis to automatically detect and identify the language with over 90% accuracy before outputting it to Markdown.
  
  [ Supported Languages (Covering 17 Major Languages) ] Python, C++, Java, R, JavaScript, Rust, Swift, C#, PHP, TypeScript, Ruby, Dart, Kotlin, Lua, Go, Bash, Scala
  
  ■ Limitations of the Auto-Detection Feature While this detection relies on highly advanced inference algorithms, please note the following limitations:
  
  - Extremely short code snippets (e.g., under 30 characters): To prevent misidentification and maintain performance, auto-detection is skipped, and the code is output as a plain text block.
  - Unsupported or niche languages: These may be incorrectly identified as one of the 17 supported languages or output as plain text (in such cases, please adjust the language tag manually).
  
  All operations are processed entirely locally within your browser. This secure-by-design approach ensures your sensitive data remains safe while you download your Markdown files or copy them to your clipboard.
