How I Vibe-Coded a Fast Client-Side N-Gram Analyzer for NLP & SEO

Hey DEV community! 👋

Analyzing N-grams (Unigrams, Bigrams, Trigrams) is essential for spotting natural phrase patterns and evaluating linguistic structure in text. However, pasting long-form drafts into web tools that process data on backend servers often raises privacy concerns.

To fix this, I vibe-coded a lightweight N-gram Analyzer that processes everything 100% in your browser.

🛠️ Key Technical Highlights:

  • Zero Backend Latency: 100% client-side JavaScript execution. Text parsing, tokenization, and phrase extraction run locally with complete privacy.
  • Instant Phrase Breakdown: Seamlessly extracts Unigrams, Bigrams, and Trigrams to audit contextual phrasing and frequency distribution on the fly.
  • Vibe Coding Workflow: Leveraged LLM prompts to rapidly construct sliding-window algorithms and clean UI array renderings for frequency tables.

💡 Vibe Coding Insight:

Implementing sliding window algorithms for Bigram/Trigram extraction in plain JS can get tricky around sentence boundaries and punctuation. Prompting the AI to isolate array transformation logic into pure, testable functions made debugging edge cases effortless while maintaining sub-second performance.
