AI Facebook Caption Rewriter — Free Tool

Features

• Keeps your meaning and rough length, changes the wording
• Written to the platform you pick, not a generic rewrite
• Works on a draft you already have — no brief needed
• Rephrase, shorten, expand and retone in the composer

How it works

1. Paste the caption you already have. These three tools work on your draft rather than on a brief — your wording is the input, not a topic.
2. Press Generate. It runs right here — no account, no card, three times a day.
3. Need more? A free account raises the limit to 50 AI generations a month.
4. It also moves generation into the composer, next to your channels and schedule — several variants per platform, then edit and schedule without leaving the page.

What you get free

Three generations a day on this page, with no account at all. Signing up is free and raises it: the Free plan includes 50 AI generations a month, Pro includes 300 and Business includes 1000 — and you can buy credits on any plan if you run out.

The reason to sign in isn't the limit, it's the workflow: generations happen where your drafts, channels, and schedule already are, so you go from brief to scheduled post without copying text between tabs. This page gives you one variant; the composer gives you several, plus improve, shorten, expand, and tone.

Getting better output

• Paste the whole thing. Half a caption gives it half the context, and it will fill the gap with something you didn't write.
• Use the per-platform page, not the general one. The platform changes the length, the register, and in some cases the rules the result has to obey.
• Run it more than once. Each run is independent, and the second attempt on a sharper brief usually beats editing the first.
• Treat it as a first draft. The fastest workflow is generate, then change one line — not generate and paste.
