Frequently Asked Questions
- Does the Word Counter support readability scoring?
- Yes. The Word Counter computes the Flesch Reading Ease score (0–100 scale) and the corresponding Flesch–Kincaid Grade Level in real time. It also shows average sentence length, average syllables per word, reading time (at 200 wpm), speaking time (at 130 wpm), and a keyword density table for the top words by frequency.
- How does the AI Prompt Studio work without an API key?
- AI Prompt Studio is a client-side tool that analyses your prompt text locally against a set of quality rules. It scores clarity, specificity, context, examples, output format, constraints, role definition, and chain-of-thought across 8 dimensions. It does not call any AI API — all scoring and suggestions run in the browser from predefined rule sets.
- What Markdown syntax does the Markdown Editor support?
- The Markdown Editor uses the marked library with GitHub Flavored Markdown extensions. Supported syntax includes headings (H1–H6), bold, italic, strikethrough, inline code, fenced code blocks with language hints, blockquotes, ordered and unordered lists, task lists ([ ] and [x]), tables, links, images, and embedded HTML.
- Can I convert the entire contents of a web page from HTML to Markdown?
- Yes. Paste any HTML — from a browser view-source, CMS export, or email template — into the HTML to Markdown converter. It handles tables, code blocks, lists, links, images, headings, bold, italic, and inline styles. The output is clean Markdown you can copy or download as a .md file.
- What case formats does the Text Case Converter support?
- The Text Case Converter outputs 14 formats at once from a single paste: camelCase, PascalCase, snake_case, kebab-case, SCREAMING_SNAKE_CASE, Title Case, Sentence case, lowercase, UPPERCASE, dot.case, path/case, CONSTANT/PATH, Train-Case, and Swap Case. Each format has its own copy button.
