Highlights Wikipedia-sourced AI-writing signals. Educational pattern matcher, not an AI detector. Runs locally. AI Writing Highlighter helps you spot common AI-writing habits tracked by Wikipedia editors while reading the web. It highlights visible article-like text that matches pattern data derived from Wikipedia's public Signs of AI writing page. The extension works locally in your browser: page text is not uploaded for analysis, no account is required, and there are no paid scans. The score is a warning sign, not a verdict. Human writers can trigger these patterns, and AI-written pages can avoid them. Use it as a reading aid when you want to notice over-polished phrasing, vague attribution, stock transitions, chatbot artifacts, formatting tells, and other habits documented by Wikipedia editors. How it works: - Finds readable text on the page - Checks paragraphs, headings, list items, and quotes against the current guide - Underlines matched wording when Chrome can do so without rewriting the page - Lightly shades flagged passages - Shows a score, match count, section count, and top categories in the popup - Refreshes the guide once per day Privacy: - No sign-up - No analytics - No telemetry - No page text uploads - No ChatGPT or model calls - No paid scans AI Writing Highlighter is an educational pattern matcher, not an AI detector. It does not prove who wrote a page.
