Processing: Browser-side text analysis.
Use these before moving pasted copy, lists, or extracted content into docs or CMS fields.
Next: Review output manually when line order carries meaning.
Processing: Browser-side text cleanup.
Use these when the same draft needs to become docs, README content, HTML snippets, or a markdown table.
Next: Preview Markdown before export when headings, tables, or code blocks matter.
Processing: Browser-side text conversion and preview.
Use these when a written draft needs to become an image card or multi-card sequence.
Next: Edit the message first; export images only after the structure is stable.
Processing: Browser-side rendering and export.
Use these for URLs, filenames, headings, labels, and content cleanup before publishing.
Next: Check existing routes before reusing a generated slug.
Processing: Browser-side text transformation.

How does reading time estimation work?
The reading time calculator uses word count and words-per-minute assumptions so you can tune estimates for different audiences.
Can I preview Markdown drafts?
Yes. The Markdown preview tool renders common Markdown syntax locally, the HTML to Markdown converter helps move simple HTML snippets into Markdown, the Markdown to HTML converter creates copy-ready HTML output, and the Markdown to Text converter strips Markdown syntax into readable plain text.
Can I generate Markdown tables?
Yes. The Markdown table generator creates pipe-table syntax with row, column, and alignment controls, while the CSV to Markdown Table converter turns pasted CSV rows into documentation-ready Markdown tables.
Can I check repeated words or keyword density?
Yes. The word frequency counter ranks repeated terms and shows density percentages for SEO drafts, editorial reviews, and content QA.
Can I generate placeholder text for layouts?
Yes. The lorem ipsum generator creates local placeholder paragraphs, sentences, and words for wireframes, mockups, docs, and layout testing.
Can I clean up title or slug text?
Yes. The text cleaner removes whitespace noise, the slug generator creates URL-safe slugs, and the text case converter creates title case, sentence case, camelCase, snake_case, and kebab-case output.
Can I check readability before publishing?
Yes. The readability score calculator estimates Flesch Reading Ease, Flesch-Kincaid grade, sentence length, syllables, word count, and reading time for English drafts.
Can I use it for books and docs?
Yes. It works for any word-count-based content, including articles, books, documentation, scripts, and briefs.
