Writing Lens

What it does

Writing Lens is an interactive MCP App that transforms text analysis into a visual experience. Instead of raw data, it renders an interactive highlight overlay that lets writers see patterns in their prose directly on the document.

Key features

• Visual Lenses: Analyze text through multiple lenses including sentence length, concrete vs. abstract language, and punctuation density.
• Interactive Overlays: Results are rendered as a heat-map style overlay, making it easy to spot rhythmic issues or overly dense prose.
• Gemini Integration: Utilizes Gemini embedding axes for deeper semantic analysis of text abstractness.
• Dynamic Plugin Architecture: Supports runtime installation of new analysis lenses via TSX compilation.
