Measure word/character/sentence counts, reading & speaking times, 5 readability indices (Flesch, FK Grade, Gunning Fog, SMOG, Coleman-Liau), 1–3 word n-grams, and social character limits.

Convert 12 identifier/prose cases, transliterate URL slugs, sort/dedupe/wrap/regex-filter multi-line lists, normalize CRLF/smart quotes, and convert Morse/NATO/ROT13.

Compare revisions with Myers line, word, or character diffing in split or unified views, compute order-independent structural JSON object diffs, and export unified .diff patches.

Convert GitHub Flavored Markdown ↔ DOMPurify-sanitized HTML, edit GFM tables in a visual spreadsheet builder, extract anchor TOCs, and export standalone HTML5 documents.

Preview Google SERP pixel widths & social cards, export HTML/Next.js metadata, build 6 Schema.org JSON-LD types, simulate RFC 9309 robots.txt rules, and generate sitemaps, hreflang & UTM links.

Convert curl commands to fetch(), axios, Python requests, and Go net/http, build Content-Security-Policy (CSP) & CORS headers, generate nginx/Vercel/Next.js redirect rules, and browse HTTP status codes.
