  description

  Content Intelligence is a free AI content detection and content quality analyzer for Chrome. It runs 100% locally in your browser with zero API calls. Your content never leaves your machine.
  Analyze any webpage, blog post, or article for AI-written patterns, content predictability, and Google's E-E-A-T quality signals. All in one click.
  Built by Certified Locals (https://certifiedlocals.com/)
  WHY WE BUILT THIS
  Let's be honest. AI content is everywhere now. And Google's Helpful Content Update is actively penalizing thin, generic, machine-written pages.
  But here's the problem. Most AI detectors just give you a percentage and say "AI" or "Human." That's not helpful. You need to know WHY content feels machine-generated and WHAT to fix.
  That's exactly what Content Intelligence does. It breaks down content into 40+ individual signals across 12 predictability checks and 28 E-E-A-T quality checks. You see the full reasoning, not just a number.
  Whether you're a content writer, SEO professional, editor, blogger, marketer, or publisher, this tool shows you exactly what's wrong and how to make it better.
  Here's what you get:
  - Detect AI-generated content on any webpage
  - Analyze content predictability with 12 advanced signals
  - Measure E-E-A-T quality (Experience, Expertise, Authoritativeness, Trust)
  - Get sentence-level analysis with fix suggestions for every sentence
  - Improve content quality for better Google rankings
  - Make sure content passes Google's Helpful Content guidelines
  - Export detailed reports for clients or your team
  WHAT DOES IT ACTUALLY ANALYZE?
  Content Intelligence gives you three powerful analysis layers:
  1. AI PREDICTABILITY SCORE (12 Signals)
  This is the core feature. Instead of a simple "AI or Human" answer, we measure how predictable and machine-like the content actually feels using 12 independent signals:
  Signal 1: Genericness Detection (18% weight)
  We scan for 90+ vague, templated phrases that AI loves to generate. Things like "in today's digital age", "it is important to understand", "helps businesses improve", "plays a crucial role", and "wide range of benefits." We also check if sentences have ANY concrete details like numbers, names, or quotes. If a sentence is completely vague, it gets penalized.
  Signal 2: Repetition Structure (14% weight)
  AI loves templates. Even when the words change, the structure stays the same. Like "This helps businesses grow" followed by "This allows companies to scale" followed by "This enables organizations to thrive." Our engine catches these structural patterns, not just exact word matches.
  Signal 3: Human Signal Absence (12% weight)
  Instead of asking "does this look like AI?", we flip it and ask "does this show ANY sign of a real human?" We look for first-person voice, opinions, experience markers, numbers, named entities, and quoted text. If ALL of these are missing, the AI score goes up significantly.
  Signal 4: Sentence Length Variation (10% weight)
  AI writes sentences of consistent length, usually 15-20 words each. Humans naturally mix short punchy sentences with longer complex ones. We measure this variation. Very uniform sentence lengths = very AI-like.
  Signal 5: Depth Penalty (8% weight)
  AI content often sounds good but keeps saying the same thing in different words. We compare each sentence to its neighbors and flag when there's more than 50% word overlap. This catches the "expanded but not deeper" pattern that AI is famous for.
  Signal 6: Contraction Absence (7% weight)
  This one is surprisingly effective. AI tends to write "do not", "cannot", "it is", "they are." Humans naturally write "don't", "can't", "it's", "they're." We measure the ratio. High formal construction ratio = strong AI signal.
  Signal 7: Transition Overuse (7% weight)
  AI overuses academic transition phrases that real people rarely write in blog posts: "Moreover", "Furthermore", "Additionally", "It is worth noting that", "First and foremost." We measure how often these appear relative to total sentences.
  Signal 8: Paragraph Uniformity (6% weight)
  AI generates paragraphs of remarkably similar length, usually 3-4 sentences each. Humans write one-sentence paragraphs sometimes, then eight-sentence blocks. We measure this variation the same way we measure sentence variation.
  Signal 9: Question Absence (5% weight)
  Humans naturally ask rhetorical questions: "But does this actually work?" or "What happens when traffic drops?" AI almost never generates questions unless specifically prompted. If a 10+ sentence text has zero questions, that's a red flag.
  Signal 10: Vocabulary Register Mismatch (5% weight)
  AI stays in one consistent tone, usually medium-formal throughout the entire piece. Real humans mix registers. They'll write something casual like "honestly, this sucked" right next to something technical like "the canonical URL returned a 301." We check whether both casual and formal vocabulary exist in the same text. If it's uniformly formal with zero casual language, the AI score goes up.
  Signal 11: Over-Smoothness (4% weight)
  AI content flows too perfectly. Every sentence connects smoothly to the next one. Human writing has natural breaks, jarring shifts, and unexpected structure changes. We measure how consistent the flow is and penalize content that's too smooth.
  Signal 12: Adjective Stacking (4% weight)
  AI loves stacking adjectives before nouns: "comprehensive, robust, and seamless solution" or "innovative, dynamic, and scalable platform." Humans rarely pile up three or more adjectives like this. We specifically detect these patterns.
  How the final score works:
  All 12 signals are weighted and combined. Then we blend that with the average sentence-level score (70/30 split) for better accuracy.
  What the scores mean:
  0-30: Low AI signals based on current heuristics
  30-55: Slightly templated
  55-75: Likely AI-assisted
  75-100: Highly predictable, AI-like
  2. E-E-A-T QUALITY SCORE (28 Signals)
  Google's E-E-A-T framework is critical for search rankings. We measure all four pillars with 28 individual checks. And we show you exactly which signals were found and which are missing.
  Experience (8 checks, scored out of 25)
  Does the author show they've actually done this?
  We check for: first-person voice, experience marker phrases (31 patterns like "when I tried" or "in my experience"), temporal markers ("last year", "in 2023", "after 6 months"), failure and learning language ("I was wrong", "lesson learned"), process descriptions ("here's what I did"), emotional authenticity ("frustrated", "surprised me"), personal outcomes with numbers ("I increased traffic by 40%"), and an absence penalty if none of these exist at all.
  Expertise (8 checks, scored out of 25)
  Does the content show deep knowledge?
  We check for: technical vocabulary density, topic diversity, explanation depth (does it explain WHY and HOW, not just WHAT), qualifying language ("depends on", "edge case", "trade-off"), counterpoint coverage ("however", "the downside"), comparison language ("unlike", "compared to"), a shallow listing penalty for content that just lists benefits without going deep, and an absence penalty.
  Authoritativeness (6 checks, scored out of 25)
  Is this from a credible source?
  We check for: named entities (brands, tools, people), topical consistency, citation language ("according to Google", "a study by Harvard"), framework references (ISO, Agile, KPI, ROI), self-attribution ("our research showed"), and an absence penalty.
  Trust (8 checks, scored out of 25)
  Can readers verify this content?
  We check for: evidence citation phrases, numbers and statistics density, hedging and honesty language ("typically", "in some cases"), balanced perspective (both pros AND cons covered), concrete vs vague examples ("like Ahrefs" vs "like various tools"), source specificity ("a 2023 MIT study" vs just "studies show"), disclosure and transparency language, and an absence penalty for claims made without any evidence.
  Every E-E-A-T sub-score shows you the full list of signals we checked, which ones were detected (green checkmark), and which are missing (circle). Plus detailed findings explaining what we found or what's lacking. Total transparency.
  3. SENTENCE-LEVEL ANALYSIS
  Every single sentence gets individually scored and labeled:
  Red: High AI-like. Heavy generic phrasing, template patterns, no specifics.
  Yellow: Moderate or generic. Some predictable patterns detected.
  Green: Low AI signals. Shows natural writing characteristics.
  Each sentence comes with a mandatory reason explaining why it was flagged and an actionable suggestion for how to improve it. We run 10+ checks per sentence including generic phrase stacking, AI template starters, specificity checks, opinion detection, structural repetition with neighbors, semantic overlap, and more.

  HONEST LIMITATIONS
  We believe in being upfront about what this tool can and can't do.
  This uses heuristic analysis, not true token probability or perplexity measurement. It can't guarantee 100% accuracy because no local tool can. Well-edited AI content may score lower than raw AI output. Very formal human writing like academic papers may score slightly higher than expected. Results are signals, not definitive proof.
  That's why our labels say things like "AI-like signals detected" instead of "this IS AI-written."
  But with 40+ signals across 12 predictability checks and 28 E-E-A-T checks, this is one of the most thorough local AI content analyzers you'll find. And it's completely free.
