Count text, draft crawler rules, prepare social tags and build campaign links. Inputs stay in your browser; review generated output before publishing.
Word count and keyword density
Counts Unicode letters and numbers separated by punctuation or whitespace. Reading time estimates 200 words per minute; languages and readers vary. Text stays in this browser.
0 words · 0 Unicode characters · 0 minute estimated reading time
Robots.txt generator
Creates a simple rule set for all crawlers. Each line blocks one path. Review rules before publishing; robots.txt controls crawling, not indexing or access security.
Campaign URL builder
Adds standard UTM parameters to your URL. Existing unrelated query parameters and fragments are preserved. No tracking happens here; analytics setup is separate.
Open Graph and X card tags
Generate markup for a page you control. This does not fetch, validate or change live pages. Social platforms may render their own preview.
