AI Summary

xPoster is a free Chrome extension that helps people write long-form articles for X (formerly Twitter) using their preferred Markdown editor. Instead of wrestling with X's built-in editor, users write their content in Markdown first, then import it into X Articles with one click. The extension handles the conversion of headings, paragraphs, images, tables, and tweet embeds. It never auto-publishes—users always review and click X's own Publish button. Everything stays local in your browser with no backend, no analytics, and no account required.

How It Works

1
✍️ You write your article in Markdown

Using your favorite text editor, you write and format your long-form article with headings, images, and links just the way you like it.

2
🛒 You install xPoster from the Chrome Web Store

One click adds the extension to your browser. No account needed, no settings to configure, no keys to copy.

3
📝 You open X Articles and the xPoster side panel

Navigate to X's article composer, then open xPoster's side panel where you can paste your Markdown or load your file.

4
🔄 xPoster converts and imports your work

Your Markdown transforms into X-friendly content. Headings become headings, images upload, tables turn into pictures, and tweet links embed properly.

5
You review what happened
✅
Everything looks great

Your article is ready to go. Click X's own Publish button when you're satisfied.

🔧
Something needs fixing

Replace broken image links, adjust formatting, or retry the import. xPoster never publishes for you.

🎉 Your article is live

You clicked Publish, and your carefully crafted article now reaches your readers on X. The whole process respects your privacy and keeps you in full control.

What is xposter?

xPoster is a Chrome extension that moves Markdown drafts into X Articles. You write in any Markdown editor, paste or load your .md file, preview what xPoster understands, and it fills the X Article editor for you. The final Publish click stays yours. It handles headings, paragraphs, lists, quotes, links, inline formatting, code blocks, dividers, images, tables, and tweet embeds. Built in JavaScript as a Chrome MV3 extension, it runs entirely in your browser with no backend, no account required, and no analytics.

Why is it gaining traction?

The hook is simple: write long posts in your preferred Markdown editor instead of fighting X's web interface. It converts Markdown to X's editor format automatically, including rendering tables as images so they display cleanly. Local images work when you point xPoster at your image folder, and web images download and re-upload through X's own uploader. The side panel gives you a preview and issue checklist before import, and a diagnostics tool helps troubleshoot when X changes its editor. It is free, open source, and privacy-focused.

Who should use this?

Writers and developers who prefer drafting in Obsidian, Typora, or VS Code before publishing on X. Technical writers who need code blocks, tables, and formatting preserved. Anyone who finds X's web editor limiting and wants a repeatable Markdown-first workflow. Not for casual tweeters or those who prefer composing directly in X.

Verdict

xPoster solves a real pain point with a clean, no-nonsense implementation. The 0.9% credibility score reflects its small star count and early-stage maturity, but the code is well-structured with smoke tests, i18n support, and clear documentation. Install from the Chrome Web Store for stability, or load from source if you want to tinker. Worth trying if you write long-form content for X and refuse to draft inside a browser textarea.
