Tweet Preview

What the Tweet Preview Does

It draws a mock X post that updates as you type, so you can judge how your name, handle and wording look together before you publish — the line breaks, where a hashtag falls, whether it reads cleanly.

It is a visual aid, not a connection to X. The avatar is a coloured placeholder, and the reply, repost and like figures and the timestamp are fixed decoration to make the card feel real.

How It Works

It takes your three inputs, escapes any HTML so the preview is safe, turns hashtags and mentions blue, keeps your line breaks, and lays it out in a card styled like an X post.

All of it runs in your browser as you type — nothing is posted or sent anywhere.

Generation algorithm

1. Enter your name and handle. Type the display name and the @ handle the post should show.
2. Type your tweet. Write the text; hashtags and mentions are highlighted in blue automatically.
3. Watch the live card. A mock X post updates on every keystroke, keeping your line breaks.
4. Screenshot or refine. Use the card to check how the tweet reads, then screenshot it or adjust the wording.

Privacy

Your name, handle and tweet text are rendered into the preview entirely in your browser. Nothing is posted, uploaded or sent to X or any server.

There is no account or history; closing the tab clears the draft, so an unposted tweet stays private.

Technical Details

Standards & references

• X (Twitter) post layout — the card mirrors X's display name, @handle, timestamp and the reply, repost and like row. Here those counts and the timestamp are fixed decoration, not live data.

Accuracy & Limitations

It is a visual mockup, not connected to X. The reply, repost and like counts (12, 34 and 256) and the timestamp (2m) are fixed, and the avatar is a gradient placeholder — there is no profile photo upload.

It does not post, fetch or validate against X's live rendering: no link-card unfurl, no images or video, no verified badge, and no weighted character count.

It highlights hashtags and mentions in blue and keeps your line breaks, so it reads close to a real post and is fine for a planning screenshot.

For the exact character limit, use the Twitter Character Counter — this tool does not count characters.

Real-World Use Cases

When to use it — and when not to

To check length use the Twitter Character Counter; to break a long post into a numbered thread use the Twitter Thread Splitter; to post or schedule, use X itself or a social scheduler.
