✦ BROWSER-LOCAL GENERATOR

Make a share card without sharing your document.

Customize a 1200 × 630 PNG for a MarkdownMaster tool or guide. The card preview, export, and optional share action run in this browser. Your Editor content is never read or inserted automatically.

Card message

Write a short, truthful message about a public tool or article. This generator does not post anywhere for you.

Choosing a template replaces only these public card fields; you can edit every field afterward.

PNG renders at 1200 × 630.Generated locally; no card data is uploaded.
Public message only

Inputs start with a public tool description. The editor’s Markdown, local history, and files are not read.

You choose the destination

Download a PNG or copy a message. Native sharing opens the operating system picker only after you click it.

No automatic posting

MarkdownMaster never submits a card to X, LinkedIn, V2EX, GitHub, or any other service on your behalf.

Use cards to share a useful task, not a generic claim.

For example, share the Markdown Formatter & Linter after explaining a real release-note or README review problem, or share the Table & Style Generator when a community discussion needs a clean GFM table. Keep the post in your own voice and link to the exact public tool that completes the task.
