Questions
- Is this Reddit 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 Reddit actually shows?
- It is the same chrome our studio uses before a post publishes: Reddit's current header layout, action row and media grid, in either of Reddit's themes. Engagement numbers are decorative, as in every scheduler's preview.
- Does Reddit cut the post off in the feed?
- Reddit shows the whole post in the feed - nothing folds, so the 40,000-character limit is the only cut.
- How long can a Reddit post be?
- 40,000 characters. Counted in Unicode code points: one plain character is one, and a link costs its full length.
Where these numbers come from: our sourced Reddit 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.
