Write captions with AI

Rewrite a caption in the client’s brand voice, or turn one caption into captions for every platform in a cross post.

AI writing tools start from the caption you already have and follow the workspace’s brand voice, the post language and each platform’s rules. You always see the result first; nothing replaces your caption until you apply it.

Rewrite a caption (Content write)

Use Content write on a single post, or on one platform of a cross post.

  1. Open the post and write a first version of the caption, or apply an AI idea. Content write is greyed out while the caption is empty, because AI needs something to start from.
  2. Under Write platform content with AI (in a cross post: Write with AI), click Content write.
  3. Choose a Rewrite action (see the table below). For Change the tone, also type the Target tone, for example “bold and playful”.
  4. Optionally add an Additional instruction, such as “keep the call to action and use fewer emojis”.
    Choose how to rewrite the caption, then click Generate content.
  5. Click Generate content. The right side shows the Source caption, the Suggested caption and What changed.
  6. Click Approve & apply to replace the caption, or change the settings and generate again. Close the window to keep your own caption.
    Compare the suggestion with your caption, then Approve & apply or close the window.
Rewrite actionWhat AI does
Improve writingFixes grammar and flow and brings the caption in line with the brand voice, keeping its meaning.
Make it shorterCuts the caption down while keeping the key message and call to action.
Add more detailExpands the caption with more context and detail.
Change the toneRewrites the caption in the tone you type in Target tone.

Applying a rewrite changes the caption like any other edit: it autosaves and is kept in the post’s version history, so you can restore the earlier text.

Captions for all platforms

In a cross post with two or more platforms, AI can adapt the caption you’re editing into a caption for every platform in the group.

  1. Open the cross post, write the caption on one platform tab, and click Captions for all platforms.
  2. Check the platform chips at the top, and optionally add an instruction such as “highlight the launch offer”.
  3. Click Generate captions. Each platform gets its own caption, hashtags and a character count.
  4. Click Apply to … on the captions you want, or Apply all. Applied captions show Applied.
One caption per platform, each with its own length and hashtags. Apply them one by one or with Apply all.

The button is greyed out when the cross post has only one platform. Add another platform first.

Tips for better captions

  • Choose the post language before you generate. In bilingual workspaces AI writes in the language set on the post.
  • Keep facts in your source caption. Prices, dates, offers and names come from what you wrote; AI doesn’t check them.
  • If results keep missing the tone, improve the brand voice and Instructions for AI writing tools in Workspaces.
