About This Site

This site hosts seven free, browser-based writing tools for SEO and GEO — Generative Engine Optimisation. Each tool helps you measure and improve a specific dimension of how your content is read by AI systems and search engines. All processing runs locally in your browser — your text is never sent to any server.

The Tools

Evidence Density Score — measures how much evidence-rich, structurally complete content a document contains. Scores across four dimensions: evidence richness, content signals, structural richness, and readability proxy. Returns a composite 0–100 score with a visual breakdown.

AI Snippet Extractor — scores every sentence in your text on five extractability criteria and highlights the sentences most likely to be cited verbatim by AI systems like ChatGPT and Perplexity.

Entity Prominence Map — finds your key named entities and shows which paragraphs they appear in, as a heat map and bar chart. Identifies where important entities go missing mid-document.

Question Coverage — detects the questions your content implicitly answers (definitional, procedural, comparative, explicit) and groups them by type with a coverage score.

Heading Visualiser — parses Markdown or HTML headings and renders your document hierarchy as a visual tree, flagging structural issues like missing H1, multiple H1s, and skipped heading levels.

Readability Analyser — measures Flesch-Kincaid grade level, passive voice percentage, sentence length distribution, and transition word density. All four metrics directly affect AI extraction reliability.

Word Frequency Counter — displays every word in your text ranked by frequency, with percentage bars and a stop-word filter. The fastest way to check keyword density and identify overused terms.

About The MicroEntrepreneur

This tool suite was built as part of a documented experiment in the "boring website" passive income model — small, focused utility sites that solve real problems, earn AdSense revenue, and require minimal ongoing maintenance. The experiment is being run in public by The MicroEntrepreneur, a site that follows one person's attempt to build real online income streams and documents what actually works.

To follow the experiment — what the site earns, how it ranks, and what gets built next — the full story is at themicroentrepreneur.com.
