How the preview works

Your text is parsed line-by-line in JavaScript: fenced code blocks are extracted first (content is HTML-escaped), then headings, horizontal rules, lists, and blockquotes. Remaining lines form paragraphs. Inline passes turn **…**, *…*, backticks, and Markdown links into safe HTML; link targets are restricted to http:, https:, mailto:, # anchors, and same-site paths starting with /.

Updates are debounced (120ms) so large notes stay responsive. There are no fetch calls for rendering — the converter is bundled inline on this page.

Common use cases

You just previewed Markdown. CloudyBot can help ship it.

Example: “Turn this outline into a customer-facing post, keep my tone, and remind me Friday to publish.” CloudyBot combines chat, memory, optional schedules, and browser tools when research is needed.

FAQ

Is my Markdown sent to your servers?

No. Conversion runs in JavaScript in your tab. No fetch calls are made for preview.

Is this full CommonMark?

No. It is a small subset for quick README and note previews: headings, paragraphs, lists, blockquotes, fenced code blocks, horizontal rules, and common inline syntax.

Is this GitHub-Flavored Markdown?

Only partially. Tables, task lists, and autolink extensions are not implemented. The goal is a fast, trustworthy preview for notes and README-style text.

Does the preview block dangerous links?

Link targets are restricted to http, https, mailto, hash anchors, and same-site paths starting with /. javascript:, data:, vbscript:, and protocol-relative URLs (//…) are dropped. Link labels and inline code are HTML-escaped so angle brackets cannot inject markup.
