π€ AI INSIGHTS β 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 β 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 β meta tags, headings, links, images, structured data, and audit results β 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:
β’ SEO Strategy Brief β prioritized action plan with critical issues, quick wins, strategic opportunities, and competitive edge tactics
β’ Generate Schema Markup β complete, ready-to-paste JSON-LD generated from your page content
β’ Technical Fixes β exact HTML code fixes for every audit issue, ready to drop into your <head>
β’ Content Gap Analysis β identifies missing sections and topics that top-ranking pages cover
β’ Competitor Insights β 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:
β’ Page classification β what the page is about and its search intent
β’ Meta description assessment β evaluates quality and suggests improvements
β’ Content quality β 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):
β’ Rewrite meta description (optimized 140-155 chars with CTA)
β’ Improve title tag (keyword-front-loaded, 50-60 chars)
β’ Generate FAQ schema questions and answers
β’ Recommend Schema.org types for your page
π 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 β dismissible and never shown again.
β‘ BUILT FOR SPEED
β’ Side panel UI β stays open as you browse, auto-refreshes on tab switch
β’ Dark theme optimized for inspector workflows
β’ 288 KB total β lightweight, no bloat
β’ No external fonts or CDN dependencies
Built by Pixelesq β the AI-native WebOps platform (AI-native Website Builder)
