Questions
- Is this X post preview free?
- Yes. There is no login and no upload: it runs entirely in your browser, and nothing you type or attach leaves your device.
- Does the preview match what X actually shows?
- It is the same chrome our studio uses before a post publishes: X's current header layout, action row and media grid, in either of X's themes. Engagement numbers are decorative, as in every scheduler's preview.
- Does X cut the post off in the feed?
- X shows the whole post in the feed - nothing folds, so the 280-character limit is the only cut.
- How long can an X post be?
- 280 characters. Counted with X's weighted rules: every URL costs 23 characters whatever its length, and most emoji and CJK characters cost 2. Premium accounts may post up to 25,000 chars; we enforce the 280 floor for everyone.
Where these numbers come from: our sourced X spec page, every figure carrying its citation and the date we last checked it.

We built these because our own agents count against exactly these limits before they publish. Let them write the post too.
