Argus by Pixelesq

All-seeing SEO inspector. Extract meta tags, audit SEO health, get AI-powered insights.

Argus is the all-seeing SEO inspector — named after the hundred-eyed giant of Greek mythology. Open the side panel on any page to instantly extract every meta tag, audit SEO health with 40+ checks, and get AI-powered recommendations using Chrome's built-in Gemini Nano. 🔍 EXTRACT — See everything search engines see • Title tag with character count (green = optimal, amber = outside range) • Meta description with length indicator • Full Open Graph tags with a live social share preview card • Twitter Card tags with a live Twitter preview • JSON-LD structured data with syntax highlighting, type badges, and validation • Heading hierarchy visualized as an indented tree • Link summary — internal, external, nofollow counts • Image audit — missing alt text, missing dimensions, lazy loading • One-click copy for every field. Export as JSON or formatted text table. 📊 AUDIT — Know your score in seconds Argus runs 40+ rule-based SEO checks across 10 categories and generates a weighted score from 0 to 100: • Title — existence, length, OG consistency • Description — existence, length, OG consistency • Headings — H1 presence, single H1, hierarchy, empty headings • Images — alt text, dimensions (CLS), lazy loading, modern formats • Links — anchor text quality, empty hrefs, internal link density • Technical — canonical, robots/noindex, HTTPS, viewport, lang, hreflang • Structured Data — JSON-LD presence, validity, schema types, breadcrumbs • Social — Open Graph, Twitter Card, image sizes • Content — word count, thin content detection, reading time • Performance — LCP, INP, CLS, TTFB via Web Vitals Every issue is labeled critical, warning, or info with a clear explanation. 🤖 AI INSIGHTS — Three-Tier AI System Argus offers three levels of AI analysis that activate automatically based on what's available: Tier 1: Claude Opus 4.6 (BYOK — Bring Your Own Key) Add your Anthropic API key in Settings to unlock the most powerful analysis. Opus 4.6 receives the full page extraction — meta tags, headings, links, images, structured data, and audit results — for deep, nuanced recommendations. Streaming responses appear in real time. Your key is stored locally in chrome.storage.local, never synced, and calls go direct from your browser to api.anthropic.com. Claude-exclusive features: • SEO Strategy Brief — prioritized action plan with critical issues, quick wins, strategic opportunities, and competitive edge tactics • Generate Schema Markup — complete, ready-to-paste JSON-LD generated from your page content • Technical Fixes — exact HTML code fixes for every audit issue, ready to drop into your <head> • Content Gap Analysis — identifies missing sections and topics that top-ranking pages cover • Competitor Insights — what top pages in your space do differently (content depth, E-E-A-T, schema, internal linking) Tier 2: Gemini Nano (on-device, no API key needed) When Chrome's built-in model is available, Argus automatically runs: • Page classification — what the page is about and its search intent • Meta description assessment — evaluates quality and suggests improvements • Content quality — identifies thin content signals and opportunities Tier 3: Static Analysis (always available, no AI required) Content assessment, missing meta tag checklist, and rule-based schema recommendations. Works offline, on any Chrome version. Shared AI actions (available with both Claude and Gemini): • Rewrite meta description (optimized 140-155 chars with CTA) • Improve title tag (keyword-front-loaded, 50-60 chars) • Generate FAQ schema questions and answers • Recommend Schema.org types for your page 🔒 PRIVACY Argus works entirely client-side. No analytics, no tracking, no data collection, no external API calls. Your browsing data never leaves your browser. The only external link is a single optional CTA to pixelesq.com — dismissible and never shown again. ⚡ BUILT FOR SPEED • Side panel UI — stays open as you browse, auto-refreshes on tab switch • Dark theme optimized for inspector workflows • 288 KB total — lightweight, no bloat • No external fonts or CDN dependencies Built by Pixelesq — the AI-native WebOps platform (AI-native Website Builder)
