Post Rewriter
Paste something that worked and get native versions for the other networks — the idea survives, the shape changes. Which is the difference between repurposing and cross-posting.

Example outputSample
- X — thread opener
We were binning 40,000 bottles a year. Nobody in the building had noticed. Here is what we did about it 🧵
- Instagram — caption
40,000 bottles a year. That was us, before the refill pouch. Same formula, 80% less plastic, and your bottle stays where it is. 🌱
- LinkedIn — post
A packaging audit turned up something uncomfortable: 40,000 bottles a year, none of them necessary after the first. The refill pouch took three months to get right — mostly the seal.
What changes between networks
| Network | Becomes | What survives |
|---|---|---|
| X | A thread with a one-line opener | The single most surprising fact, first |
| A considered post with a stake | The reasoning and what it cost | |
| A caption under 125 before the fold | The number and the benefit | |
| TikTok | A spoken hook plus on-screen text | The tension, said out loud |
| Threads | A short conversational take | The opinion, minus the build-up |
| YouTube | A description with the hook up top | Search terms and the promise |
Rewriting well
- 1
Rewrite your winners, not your backlog
The best candidate is something that already worked. Reach was limited by who happened to be online that day, not by the idea — and a rewrite gives the same idea a second audience.
- 2
Let the structure change, not just the length
A good LinkedIn post and a good X thread are different objects. If the rewrite is the same shape with fewer words, it will read as a truncation, because it is one.
- 3
Keep the specifics, cut the connective tissue
Numbers, names and concrete details survive every format. The transitions and throat-clearing around them are what should go when the limit tightens.
- 4
Read it before it publishes
Rewrites drift furthest on claims — a hedge becomes a promise, an 'up to' quietly disappears. It takes ten seconds to check and it is the one thing worth checking.
Questions
- How is this different from copy-pasting?
- A rewrite changes the shape, not just the length. A LinkedIn post becomes a thread with a different structure on X, and a hook plus on-screen text for TikTok. Pasting the same words into five boxes is what makes cross-posting obvious.
- Is it free?
- Yes, on the free plan — 10 AI generations a month, no card. One rewrite run counts as one generation.
- Can I rewrite from a blog URL?
- Inside Mediux, yes — paste a URL and it pulls the article to work from. On this page, paste the text you want reworked.
- Will it keep my meaning?
- That is the constraint it works under: same argument, same claims, different shape. It is worth reading before publishing anyway — nothing should go out unread, whoever wrote it.
- Does it keep my brand voice?
- With a saved voice, yes — the rewrite inherits your tone the same way a fresh generation does. Without one, you get a competent neutral register.
- Can I rewrite an old post to run again?
- That is the most valuable use of it. A post that did well a year ago has a new audience now, and a genuine rewrite is not a repost — it reads as new because it is.
