Free caption tool
Caption rewriter
Have a caption that is nearly right? Paste it in, tick the styles you want and get a version for each one side by side. The rewriter uses simple, predictable rules such as contractions, word swaps and trimming filler words, so it never invents facts about your post. Everything happens in your browser.

How to use the caption rewriter
- Paste your caption into the box.
- Tick one or more styles. Casual, professional, funny and shorter are selected to start.
- Press rewrite to see one version per style.
- Copy the version you like, or combine lines from several versions.
What each style does
- Casual: uses contractions and friendlier words.
- Professional: expands contractions, removes slang, emojis and hashtags, and tidies capitals and punctuation.
- Funny: keeps your caption and adds a light-hearted closing line.
- Shorter: removes filler words like “really” and “basically” and keeps the first sentences.
- Add emojis: places matching emojis after relevant words.
- Add hashtags: builds a few hashtags from the keywords in your caption.
- Aesthetic: soft lowercase with calm punctuation.
- End with a question: adds a question to invite comments.
- Story format: splits the caption into short paragraphs with a story-style opener.
Rule-based, not AI
This tool does not use AI. Each style is a set of hand-written rules applied to your text, so the result stays close to what you wrote and never adds claims you did not make. That also means it cannot understand context the way a person can, so give each version a quick read before posting.
Because the rules run in your browser, your caption is never uploaded and you can rewrite as many captions as you like.
Frequently asked questions
Is the caption rewriter free?

Does the rewriter use AI?
No. It applies predictable rules, such as swapping words and adjusting punctuation, entirely in your browser.
Why does the funny version change each time?
The funny, question and story styles pick from a small set of hand-written lines, so pressing rewrite again can give a different ending.
Is my text stored or shared?
No. Your caption stays on your device and is not sent to a server.
Can I rewrite captions for any platform?
Yes. The rewrites work for Instagram, TikTok, Facebook, LinkedIn and anywhere else you post text.
