Turn one caption into 8 platform-ready versions with limits checked.
Updated October 2026
Private by design: your files are processed on your own device and never uploaded.
How to use
- 1 Paste your full original caption or post.
- 2 Add an optional link, hashtags (most important first) and a call to action.
- 3 Read the eight cards. Grey text is hidden behind each platform's 'more' link.
- 4 Copy or share each version straight into the app.
Why the same caption fails on every platform
X cuts you at 280 characters, Instagram hides everything after 125, LinkedIn after 210, TikTok wants a short caption and Pinterest wants keywords instead of hashtags. Posting the same text everywhere means the hook is buried on some apps and the post is truncated on others. This tool rewrites the length, hashtags and link placement for each platform from one source text.
What changes per platform
Instagram gets the full caption, 'link in bio' and up to 10 hashtags after dot separators. X gets the strongest sentences trimmed to fit with the link and two hashtags. LinkedIn gets one sentence per line for readability. TikTok gets a short caption and four hashtags. Pinterest gets a keyword-rich description. YouTube Shorts gets a title under 100 characters with #Shorts.
Write once, edit lightly
Treat the outputs as strong first drafts. Read each one in the voice of that platform, adjust a word or two, and post. Pair it with the Content Calendar Generator to plan what to repurpose each week.

Questions
Does it rewrite my text with AI?
No. It cuts, formats and rearranges your own words by each platform's rules, so your voice stays intact.
How are links counted on X?
X counts every link as 23 characters; the tool reserves that space.
Why are hashtags different per platform?
Instagram rewards several relevant tags, X and Threads favour one or two, LinkedIn three, and Pinterest favours keywords.
Can I edit the result?
Edit your original and every version updates instantly.
Is anything saved?
No. Everything stays in your browser.
