ZeRegLens: read DORA, NIS2 and CSSF texts with local AI

Description

Sovereign reading assistant for EU financial and cyber regulation: outline, cross-references, glossary, export. AI stays local. ZeRegLens is a reading assistant for EU regulatory texts. It adds a side panel to your browser that parses the regulation you are reading and gives you a navigable outline, bidirectional cross-references, a glossary of legal terms, AI-powered summaries, and structured export. No data is sent to any server. No account is needed. HOW IT WORKS Open a regulation on one of the six supported publishing platforms, then click the toolbar icon. A side panel appears with the full reading toolkit. The extension detects the document structure automatically. DOCUMENT OUTLINE The extension parses the page and builds a hierarchical outline of the regulation: titles, chapters, sections, articles, and recitals. Click any heading to scroll the page to that section. A marker shows which section is currently visible. CROSS-REFERENCES Regulatory articles constantly reference other articles. ZeRegLens detects these references in both English and French and builds a two-way graph. For each article, you see which articles it cites and which articles cite it. Clickable links are injected into the page text so you can jump to any referenced article. GLOSSARY The extension ships with a built-in glossary of 68 legal terms drawn from EU financial and cybersecurity acts. When you open a regulation, every glossary term found in the text is highlighted. Click to see the definition and its legal source. Matching is precise: longest match wins, acronyms are case-sensitive, and matches respect word boundaries. The glossary is available in English, French, and German. AI SUMMARIES ZeRegLens can generate a plain-language summary of any article. By default, summaries are produced locally using Chrome Built-in AI (Gemini Nano), meaning the text never leaves your computer and no API key is needed. The AI also performs modal verb analysis: it distinguishes binding obligations ("shall"), permissions ("may"), and recommendations ("should"), which carry distinct legal weight in regulatory texts. An optional remote mode lets you connect your own AI endpoint. Remote AI requires explicit consent on a screen that names the exact server and model. Only the article text is sent; the page URL, browsing history, and identity are never transmitted. Summaries are cached locally under SHA-256 hashed keys. You can clear the cache at any time. EXPORT You can export the panel data in four formats: CSV, TSV, Markdown, and JSON. Exports include the outline, article text, cross-references, and glossary matches. Cell values are escaped to prevent formula injection when opening files in a spreadsheet. PRIVACY All processing runs in your browser. The extension makes zero network requests in its default configuration. It collects no personal data, no usage data, and sends no analytics or telemetry. The only possible network call is the optional remote AI endpoint that you configure yourself. Permissions are minimal: sidePanel (reading panel), storage (local settings and cache), scripting (content script on supported pages when you click the icon). The extension cannot see your other tabs. Open source under the MIT license. The full source code is published on GitHub.
